Cisco ASA 5505 Security Plus - Routing problems

[Slamjam99]

Hi there,

I'm a bit new to this so I'll try to be as clear as I can.

We have just purchased a Cisco ASA 5505 Security Plus firewall. I have gone through the default settings foe setting up teh firewall with a default route of 0.0.0.0 going out of the Outside interface.

My problems comes when I enable WebVPN on the ouside interface I try to connect and get an error saying no route to the host.

I have setup two interfaces - Inside and Outside. The Inside int has NAT configured with some ACL's.

Any ideas ?

Can you get out to the internet through the ASA? Is it the VPN you are having trouble with? Do you have "reverse route" configured?

Hi Burt,

Yes I can get to the internet and yes its the VPN I'm having trouble with.

A reverse route ??? I have only a Inside to Outside route.

How should I configure a reverse route ?

Many thanks.

Are you doing the config via command line or GUI? If you can get to the command line, do a show run and post that. I specified a dynamic map, which is mapped to my outside interface. It is under this dynamic map configuration where you name the map and use the reverse-route command. If you need a sample config, let me know.
