No Internet access

macboy276 — Tue, 12 Mar 2019 02:54:49 GMT

Hi everybody,

I am unable to access internet with one of the vlan. i have two vlans

VLAN 2 192.168.1.0

VLAN 8 172.168.1.0

When i am on vlan 2 i can access to internet. when i work with vlan 8, i cannot access to internet. As a matter of fact VLAN 8 (172.168.1.0) is new. I need to know what else i need to configure to get access. the following is the configuration of my cisco ASA firewall. Any help will be apprieciated.

Thanks

Hi,

I dont see any "nat" statement for interface "Internal_LAN"

nat (Internal_LAN) 172.168.1.0 255.255.255.0

The ID number mentioned you can choose yourself since you seem to use multiple different public IP addresses for Dynamic PAT configurations.

The above would enable Dynamic PAT for the users behind "Internal_LAN" interface and therefore enable Internet connectivity.

It seems to me that this network is actually a public network and not one belonging to the private network range.

Hope this helps

Does this nat command will have any issues with vlan 2. There is also no nat for vlan 2 available, how it is getting internet access.

Hi,

The above command doesnt really refer to the interface "inside" at all so it doesnt really have effect on it.

The Internet works from behind "inside" interface even with the NAT0 configuration because the NAT0 is not configured for every destination address. The NAT0 applies only when the destination networks are those configured in the ACL below

access-list inside_nat0_outbound extended permit ip Inside_Subnet 255.255.255.0 host Email_Gateway

access-list inside_nat0_outbound remark SharePoint

access-list inside_nat0_outbound extended permit ip Inside_Subnet 255.255.255.0 host SharePoint

access-list inside_nat0_outbound extended permit ip Inside_Subnet 255.255.255.0 NEW_VPN_POOL 255.255.255.0

I have used the following command

nat (Internal_LAN) 8 172.168.1.0 255.255.255.0

the above command is giving me the following error and no internet.

305006|Email_DNS|53|||portmap translation creation failed for udp src Internal_LAN:172.168.1.72/55035 dst inside:Email_DNS/53

When i use

no nat (Internal_LAN) 8 172.168.1.0 255.255.255.0

the following error appears in log

Teardown TCP connection 1307075 for outside:108.59.5.130/443 to Internal_LAN:172.168.1.72/2273 duration 0:00:00 bytes 0 TCP Reset-O

Hi,

To have a complete Dynamic PAT configuration you would need a "global" command with ID 8 also.

Or you can replace the ID 8 in the above command with something that already has a "global" command

Like these

global (outside) 1 12.18.13.21 netmask 255.255.255.255

global (outside) 2 12.18.13.22 netmask 255.255.255.255

global (outside) 3 12.18.13.23 netmask 255.255.255.255

global (outside) 4 12.18.13.24 netmask 255.255.255.255

global (outside) 5 12.18.13.25 netmask 255.255.255.255

The first log message you post is a problem between "Internal_LAN" and "inside". That might probably be corrected by adding

static (inside,Internal_LAN) 192.168.1.0 192.168.1.0 netmask 255.255.255.0

Hello,

So I was checking your configuration, I understand the security levels are set to 100 on both inside and Internal_LAN, if you change the security level on Internal_LAN to something lower than 100 you should be able to access everything as you were and also add the PAT configuration that your previous collaborator indicated.

Configuration:

enable

config t

interface Vlan8

security-level 90

nat (Internal_LAN) 8 172.168.1.0 255.255.255.0

Try it out, that way you don't need to add additional NAT configuration.

No Internet access

macboy276 — Tue, 22 Oct 2013 22:03:12 GMT

I try using the following config but it is still not working.

interface Vlan8

security-level 90

nat (Internal_LAN) 8 172.168.1.0 255.255.255.0

No Internet access

jumora — Tue, 22 Oct 2013 22:04:18 GMT

I forgot to indicate, you have a static NAT configuration that maps the inside network to the internal_LAN

static (inside,Internal_LAN) Inside_Subnet Inside_Subnet netmask 255.255.255.0

name 192.168.1.0 Inside_Subnet

If you need the Internal_LAN network to be able to access anything on the inside I would rather configure the NAT exemption that states that you will not require NAT from the inside interface network to the internal_LAN network but that is all up to you if you want to configure it or not.

access-list inside_nat0_outbound permit ip any 172.168.1.0 255.255.255.0

NOTE: The line above is part of the next configuration that applies the NAT exemption on the inside interface:

nat (inside) 0 access-list inside_nat0_outbound

So the configuration would like this:

enable

config t

interface Vlan8

security-level 90

nat (Internal_LAN) 8 172.168.1.0 255.255.255.0

global (outside) 8 12.18.13.X

No Internet access

macboy276 — Tue, 22 Oct 2013 22:04:43 GMT

follwing error is logged

305006

portmap translation creation failed for tcp src Internal_LAN:172.168.1.72/1807 dst outside:95.211.37.197/80

No Internet access

macboy276 — Tue, 22 Oct 2013 22:12:41 GMT

that means with this new config i will still be able to connect to inside network and have internet access.

global (outside) 8 12.18.13.X

With what X has to be replaced

No Internet access

jumora — Tue, 22 Oct 2013 22:17:48 GMT

I put an X meaning an IP of your choice if you still have available IP addresses but if you do not and you do not care if it goes out with the same global IP address as the people on the inside then you can just add the next line but remember to change the security levels.

nat (Internal_LAN) 1 172.168.1.0 255.255.255.0

Jouni Forss — Wed, 23 Oct 2013 14:58:42 GMT

Hi,

Could you let me know if you have tried the configuration I originally suggested. I mean creating a "nat" statement for the "Internal_LAN" thats ID number matches one of the existing "global" or make a new "global" for it. And also if the "Internal_LAN" needs to access "inside" you could have added the "static" command suggested.

It seems there has been some other suggestions in between that have again suggested completely different things. I would have been interested to know what the situation is after the suggested changes before going and doing something completely different.

If you are changing a lot of NAT configurations for the new "Internal_LAN" interface I would suggest checking the output of

show xlate | inc 172.168.1

To see if you need to use some variant of the "clear xlate" command to clear old translations still active on the firewall. You should not use the "clear xlate" without additional parameters as otherwise it clears all translations on the firewall in the mentioned form of the command

You can use

clear xlate ?

To view the different optional parameters for the command

Did you remove the "nat (Internal_LAN) 8 172.168.1.0 255.255.255.0", you need to remove it before adding "nat (Internal_LAN) 1 172.168.1.0 255.255.255.0"

No Internet access

macboy276 — Wed, 23 Oct 2013 19:31:49 GMT

I removed the old nat and add

nat (Internal_LAN) 1 172.168.1.0 255.255.255.0

interface vlan8

security-level 90

It worked. Now i have internet access.
