Cisco ASA 5505 site to site Multiple subnet.

osolbakken
Level 1
Level 1

Hi. I need some help configuring my cisco asa 5505.

I've set up a VPN tunnel between two ASA 5505

Site 1:

Subnet 192.168.77.0

Site 2:

Have multiple vlans and now the tunnel goes to vlan400 - 192.168.1.0

What I need help with:

From site 1 i need to be able to reach another vlan on site 2. vlan480 - 192.168.20.0

And from site 1 I need to reach 192.168.77.0 subnet from vlan480 - 192.168.20.0

Vlan480 is used for phones. In vlan480 we have a PABX central.

Is this possible to do?

Any help would be greatfully appreciated!

Hi,

The addition of a new network to the existing L2L VPN should be a pretty simple process.

Essentially you will have to add the network to the Crypto ACL present in the "crypto map" configurations. You will also have to configure the NAT0 configuration for it in the proper interfaces of the ASA. These configurations are all done on both ends of the L2L VPN connection.

Looking at your above configurations it would seem that you will need the following configurations

SITE 1

  • We add the new network to both the crypto ACL and the NAT0 ACL

access-list outside_1_cryptomap extended permit ip 192.168.77.0 255.255.255.0 192.168.20.0 255.255.255.0

access-list inside_nat0_outbound extended permit ip 192.168.77.0 255.255.255.0 192.168.20.0 255.255.255.0

SITE 2

  • We add the new network to the crypto ACL
  • We create a new NAT0 configuration for the Vlan480 interface as it has no previous NAT0 configuration

access-list outside_20_cryptomap_1 extended permit ip 192.168.20.0 255.255.255.0 192.168.77.0 255.255.255.0

access-list VLAN480-NAT0 remark NAT0 for VPN

access-list VLAN480-NAT0 permit ip 192.168.20.0 255.255.255.0 192.168.77.0 255.255.255.0

nat (vlan480-Telefoni) 0 access-list VLAN480-NAT0

These configurations should pretty much do the trick.

Let me know if it worked

nat (vlan480-Telefoni) 0 access-list VLAN480-NAT0

Hi,

Thanks again for the quick response!

Should ping work? Could not get echo reply

Hi again.

Tried ping from the asa on site 1. That did not work.

But for a pc in 192.168.77.0 network it worked great! Thanks!

Hi,

From the perspective of the ASA configurations it should work

You can always test the rules from each direction

For example

Site 1

packet-tracer input inside icmp 192.168.77.100 8 0 192.168.20.100

Site 2

packet-tracer input vlan480-Telefoni icmp 192.168.20.100 8 0 192.168.77.100

If the actual ICMP doesnt work I would also consider the possibility that software firewall on the actual hosts might cause problems.

By the way, your Site 2 ASAs "outside" interface ACL is pretty unsecure as its allowing ALL traffic

access-list outside_access_in extended permit ip any any

access-group outside_access_in in interface outside

You do seem to have hosts/servers that have Static NAT to a public IP address so you probably need to allow some traffic. I would suggest you determine the services that need to be allowed and block rest of the traffic. Its a considerable security risk to have everything allowed from the public network.

- Jouni

Hi.

Thanks for the tip.

would the servers that have static nat be affected if i "close" down the outside interface.

If so should I then just create an any-any rule based on the service.

example:

RDP (3389) need to be open for several servers. should i then create as I said an any-any rule for that service?

--

Orjan

Hi,

Removing the current "permit ip any any" rule would affect the servers IF they need to be reached from the Internet which I suspect they need.

You could allow only the needed ports for each server.

And ofcourse if you can limit the source addresses for these rules then the more secure it will be. Naturally some traffic needs to be allowed from all source addresses, HTTP/HTTPS for example.
