ASA VPN Help

DOUGLAS DRURY
Level 1
Level 1

Hi,

ASA's are not my strongest point.  I had to make some changes to my clients ASA when the changed provider.  The ASA used to be NAT'd to an NTU the old provider gave us, the new Provider the ASA is NAT'd to a modem.  The only thing that doesn't work right is the VPN.

When the IPSec VPN connects we can't ping, telnet/ssh or RDP to any of the devises.  My guess is the ACL's aren't quite right.  Could somebody have a look at the config and suggest anything?

WAN---ASA---LAN(192.168.20.x)

I've removed usernames/passwords and changed the public IP address around for security.

Doug,

The nat is going to work from inside to outside so if the LAN is 192.168.20.0 the nat should be like this:

access-list NONAT extended permit ip 192.168.20.0 255.255.255.0 172.16.0.129 255.255.255.128 

Just to get this clear you are using Remote VPN you should add the 192.168.20.0 to the split tunnel ACL:

access-list SPLIT_TUNNEL standard permit 192.168.20.0 255.255.255.0

Try this:

access-list NONAT extended permit ip 10.71.79.0 255.255.255.0 172.16.0.129 255.255.255.128

-JP-

Thanks for the reply.

Just to clarify even though the production LAN is 192.168.20.0 I should still try access-list NONAT extended permit ip 10.71.79.0 255.255.255.0 172.16.0.129 255.255.255.128 or should i swap 10.71.79.0 for 192.168.20.0?

Thanks

Doug

Are you trying to do Ipsec Remote access or site to site?

It looks like you also have some extra no-nats:

access-list NONAT extended permit ip 192.168.20.0 255.255.255.0 172.16.0.0 255.255.255.0
access-list NONAT extended permit ip 192.168.20.0 255.255.255.0 172.16.0.0 255.255.255.128

The second rule is covered by the first one.  I would take out the second one to make sure it doesn't get confused.

Also, you mentioned this worked before the provider change?  Is phase 1 coming up for sure?
