I am trying to create a site to site VPN using Cisco ASA and ISR:
As HQ site, I have an ASA 5505 connected to an 1801 ADSL router. Internet access out from the site is OK, and I can http onto the 1801 router from outside. I cannot seem to get to the ASA at all, the logging in the ASA seems to indicate that traffic is being denied by something.
The test site that I am trying to connect also has an 1801 router with the VPN IOS. When trying to create the tunnel, it gives error messages relating to visibility of the ASA peer. (I read this to be much the same as the above issue)
I have a running config of the ASA if it helps - I would appreciate any pointers in this area as this quite urgent for me.
