Multiple WAN on same interface in ASA

[Rawit2015]

Since I have never worked with ASA having a multiple WAN on same interface, how this can be achieved? My ISP has given me /29 IP address, and I assigned xxx.xxx.xxx.xxx/29 to one physical interface, set gw, route for gw, nat, access lists, etc. My question is, how can I use other WAN addresses from same scope and make forward each one of them for each internal subnet. For example: xxx.xxx.xxx.xxx/29 to 192.168.1.0/24, xxx.xxx.xxx.xxy/29 to 172.16.1.0/23, xxx.xxx.xxx.xxz/29 to 10.0.0.0/24...

Can someone provide an example?

Also how can this be achieved if each WAN is assigned with physical interface on ASA (if it is possible)?

Hello, 

This can be achived by configuring NAT rules.

For example, 

object network host_01
 host 192.168.1.100
 nat (inside_01, outside) static xxx.xxx.xxx.xxx
object network host_02
 host 172.16.1.100
 nat (inside_02, outside) static xxx.xxx.xxx.xxy
object network host_03
 host 10.0.0.100
 nat (inside_03, outside) static xxx.xxx.xxx.xxz

If you have dedicated physical interfaces for different WAN, the configuration is pretty similar:

object network host_01
 host 192.168.1.100
 nat (inside_01, outside_01) static xxx.xxx.xxx.xxx
object network host_02
 host 172.16.1.100
 nat (inside_02, outside_02) static yyy.yyy.yyy.yyy
object network host_03
 host 10.0.0.100
 nat (inside_03, outside_03) static zzz.zzz.zzz.zzz

Hi Boris,

I am having multiple results now. At the customers site I've got reply from ASA about overlapping and when I came into our office and try to test once again, it was successfully added... One thing I noticed, when I set command (please check the host IP): (instead of two different hosts, I tried to set 2 WANs on same IP address)

I noticed that only last NAT was added xxx.xxx.xxx.xyy, but not xxx.xxx.xxx.xxx.

Also I have assigned one public WAN into phisical interface, as it has to be dynamic NAT. Does this somehow affect why it didn't accept the last static NAT?

object network host_01
 host 192.168.1.100
 nat (inside_01, outside) static xxx.xxx.xxx.xxx

object network host_01
 host 192.168.1.100
 nat (inside_01, outside) static xxx.xxx.xxx.xyy

Hi,

Very easy, just create two objects with different names (host_01 and host_02) but with the same host IP:

object network host_01
 host 192.168.1.100
 nat (inside_01, outside) static xxx.xxx.xxx.xxx

object network host_02
 host 192.168.1.100
 nat (inside_01, outside) static xxx.xxx.xxx.xyy

[Rawit2015]

Yes, of course. Sorry mate. I've been running constantly 3 days for approx 10h per day, so I missed one small thing which is quite logical, and that is object name. When I set object, and set new IP it only overwrote the the current object. Naming it differently it is creating new separate entity.... Of course.

What about assigning 1 WAN on physical interface. Will this affect somehow NAT rule that you set or I need to remove IP address from interface and set each IP as object and manipulate traffic with them? Can I use "IP assigned" WAN interface and get traffic for other WANs as well? Will router/firewall accept the packets even though on WAN interface is xxx.xxx.xxx.xxx, but traffic is sent for xxx.xxx.xxx.xxy?

Since I have never before set multiple WAN on same interface, what is happening in the background? ISP sends traffic for subnet xxx.xxx.xxx.xxx/29, two addresses are for network and broadcast, one is ISP gateway, and you have 5 left to use. Usually if there is /30, it would be 1:1 communication (ISP GW to your router/firewall) which is quite clear to me, but what is happening with 5 WANs? As I can see from command that you've set, "virtually assigned" as network objects, and NAT-ed to specific network or machine static 1:1, correct? Does this mean that traffic from ISP is sent via GW to firewall for all 5 WANs, and in the header of the packet, there is IP which declares which WAN it is? When firewall/router gets the packet, it interprets and forwards per rule that you've set or?

I assume that port forwarding is the same thing, you use interface which is assigned with IP address or?

I'll try to answer the questions :)

What about assigning 1 WAN on physical interface. Will this affect somehow NAT rule that you set or I need to remove IP address from interface and set each IP as object and manipulate traffic with them?

No, you don't have to remove IP-address from interface. Moreover, you have to configure IP-address on interface to make routing work.

Can I use "IP assigned" WAN interface and get traffic for other WANs as well? Will router/firewall accept the packets even though on WAN interface is xxx.xxx.xxx.xxx, but traffic is sent for xxx.xxx.xxx.xxy?

Sure you can. The magic is with ARP protocol. When you don't have any NAT rule configured, ASA answers only to ARP requests for IP address, assigned on the interface. When you configure NAT rule, ASA begins to answer to ARP requests for both IP addresses (assigned to interface and configured in NAT rute.

Since I have never before set multiple WAN on same interface, what is happening in the background? ISP sends traffic for subnet xxx.xxx.xxx.xxx/29, two addresses are for network and broadcast, one is ISP gateway, and you have 5 left to use. Usually if there is /30, it would be 1:1 communication (ISP GW to your router/firewall) which is quite clear to me, but what is happening with 5 WANs?

Again, magic is with ARP. ARP works fine in the background.

As I can see from command that you've set, "virtually assigned" as network objects, and NAT-ed to specific network or machine static 1:1, correct? Does this mean that traffic from ISP is sent via GW to firewall for all 5 WANs, and in the header of the packet, there is IP which declares which WAN it is? When firewall/router gets the packet, it interprets and forwards per rule that you've set or?

Absolutely correct. When ISP receives the packet from somewhere outside with destination address xxx.xxx.xxx.xyy (virtually assigned) Provider's equipment already knows the route to xxx.xxx.xxx.xyy as directy connected network (xxx.xxx.xxx.xxx/29). The only information it needs to send the packet is the MAC-address. So it makes an ARP request. ASA with NAT rule configured to virtually assigned address xxx.xxx.xxx.xyy answers the ARP request with its MAC-address. So ISP's router can now successfully send the packet with destination address xxx.xxx.xxx.xyy. When ASA receives this packet, it matches IP-addess xxx.xxx.xxx.xyy with configured NAT rute, performs the untranslation to 192.168.1.100 and send the packet further.

I assume that port forwarding is the same thing, you use interface which is assigned with IP address or?

Yes. correct. With port forwarding you can use IP address of WAN interface in your NAT rule (PAT rule to be precise).

Thank you mate for clarifying things. Tomorrow I will configure ASA. The only thing what is left is ASA is somehow blocking Meraki cloud communication with switches. I noticed that Meraki is set quite long list of IPs and 4 ports for outbound traffic. By outbound, I presume they need permit rule on access list from those IPs to internal network for specific port. The only thing I am not sure if port fwd is needed, because by some logic, interface is set to be static so no IP assignment to Meraki sw, which again means you cannot point traffic as you don't know "where"... I am quite disappointed with Cisco Meraki documentation as it doesn't explain what is happening in the background. Does switches contact cloud service or (traffic should be state full inspected), and/or is the cloud service also sending traffic from the cloud towards switches which means you need to set access control rules for outside interface -> "in"...

Ah yes, one more thing. Do you have any experience with direct link ASA - HP MSM720 controller? On controller there is port that is set as VLAN 10. On other side is interface of ASA. Previous versions of IOS/5505 would allow to create interface VLAN 10, now I see that they've changed the logic and you need to create sub-interface and then assign IP and VLAN. The confusion starts in this area. By mistake I configured physical interface with native VLAN (by definition it is considered as VLAN 1), on other side is MSM720 with VLAN10. How is possible that I could ping ASA and vice versa if controller has VLAN 10, and ASA native VLAN? Moreover when I configured sub-interface with VLAN 10, and tried to ping controller (opened Wireshark) I didn't get any traffic?

Command that I used is:

#conf t

#interface GigabitEthernet 1/5.10

#vlan 10

#ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx

#no shut

(Also on main interface I set no shutdown)...

[Boris Uskov]

Hello, Unfortunately I don't have any experience with Meraki, so not able to comment.

HP MSM720 - also never used. But I'll try to share my thoughts...

What does it mean "on other side is MSM720 with VLAN10"? It seems, that MSM has an access port with vlan 10. No trunk port (no 802.1q tagging). 

ASA with native vlan 1 also does not perform any 802.1q tagging. So from VLAN perspective it absolutely does not matter, what vlan number is configured on access ports from both sides. That is why MSM is pingable when you made your first configuration.

ASA does not support Cisco Discovery Protocol (CDP), so, there is no way to get "Native vlan mistmatch" error. 

When you changed your configuration on ASA to vlan 10, ASA starts to tag L2 frames on that interface with tag vlan 10 (802.1q trunk). The frame goes to MSM, but it is configured to accept only untagged frames. In this situation you have to change the port configuration on MSM to accept tagged frames in vlan 10.

When you used to have ASA5505, I suspect you had something like this:

interface Ethernet0/0
 switchport access vlan 10
interface vlan 10
 ip address xxx.xxx.xxx.xxx 255.255.255.0

Is this case Ethernet 0/0 is configured also as Access port (unless switchport mode trunk is configured), and it also does not tag frames.

[Rawit2015]

Hi Boris,

to explain bit further. ASA is configured as native VLAN but no possibility to set VLAN ID as it is physical port that is configured (at least not on 5508X that I use and IOS 9.6.2). When you configure subinterface then you have possibility to set VLAN ID. Yes the MSM720 has untagged port, but again, if there is VLAN 10 untagged on controllers side, and NATIVE vlan (which I presume is VLAN 1) also access or untagged port.

Quote:

"ASA with native vlan 1 also does not perform any 802.1q tagging. So from VLAN perspective it absolutely does not matter, what vlan number is configured on access ports from both sides. That is why MSM is pingable when you made your first configuration."

How come that ID doesn't matter? This is "separation" of the network on the L2...

[Boris Uskov]

Hello, the separation on the L2 can be achived by 802.1q tagging. So, what is the problem? You have vlan 1 on ASA which is untagged and vlan 10 on MSM, which is also untagged. Yes, we have vlan id mistmatch, but everything works fine, isn't is?

Or. maybe, you want to have one IP subnet on vlan 1 and the other IP subnet on vlan 10? In this case you can simply use another physical interface on ASA (without creating any subinterfaces) and connect it dirrecty to MSM.

[Rawit2015]

yeah, you are right. 11 years ago I was doing CCNA and I forgot some basic things as last 5 years I was a developer. In this case I was confusing things with something else...

Thank you once again mate.

Cheers :) 

[Boris Uskov]

You are welcome! Good luck! :)

[Rawit2015]

Hi Boris,

I have set everything and it works (at least regarding port forwarding). The thing that I am missing is internet connection from inside to outside. Static NAT is set and I can get from outside (multiple WAN) to that server per specific ports, but I don't have ability to go from server to "cloud/internet"

Can you please help me with this also?

(Here is the config - I know there is a lot of things that needs to be cleaned afterwards as I was trying to set, and failed miserably :) )

Hello, try to use packet-tracer utility to verify packet flow. It will show you the reason, why the traffic is droped.

For example, let's emulate http-request from 192.168.96.2 Server to google.com (IP address 74.125.232.238). To emulate this transaction issue:

packet-tracer input ServerTV tcp 192.168.96.2 56123 74.125.232.238 80

Hi Boris,

since nothing is currently connected to this server (there isn't device attached on that IP address on that port, is it possible to simulate that?). 

I have set two different subnets (WAN). WAN1 for guestWiFi and default route metric 1 (dynamic NAT), WAN2 should be for TV server, and for that I have set default route of WAN2 with metric 2 (static NAT). Access lists for both networks are set to allow from inside to outside without any restrictions, so permit any any... There must be something with NAT that is blocking, as I can get access from outside to inside, but from inside to outside I cannot. Reading the configuration, I cannot find why...
