ASA5505 telnet from across Site to Site VPN tunnel doesn't prompt for password


I have a site to site VPN tunnel between cisco ASA5525 and ASA5505.  I allow telnet from my network 10.x.x.x inside and I get a blank black screen from telnet but if I change it to inside it brings up password prompt.

My IP is 10.x.x.x

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This could be a routing/RPF issue. When the allow statement is a specific subnet, RPF expects traffic to come from a certain interface. VPN traffic is kind of odd in that it is treated like inside traffic because it is trusted, but when it comes to certain rules the physical interfaces must be referenced - NAT would be one of those rules. When you use a default for telnet access, the ASA doesn't need to worry about the source interface anymore which could be why that works.

If you are running 8.3+ code, find the nat exemption rule for this traffic and add the "route-lookup" keyword to the end of the statement. This might allow you to specific the subnet for telnet and get a proper response.
