I have an ASA 5505 with an inside network configured normally plus another security level 100 network we call 'transit'. Data flow is enabled across the interfaces, and it does work, but in order to get communications between hosts on each side, I have to add routing statements manually on the host systems. For example, a Windows host on the 'transit' network has to have a 'Route Add' statement run on it in order to respond to traffic from the 'inside' network, and vice-versa. Once the statements are added on both sides, the traffic works fine. I'm not able to add a static route on the ASA to the 'transit' network, for example, if I try I get an error in the GUI client that it is a connected network and can't have a static route to it.
Is there some way to configure the ASA to move the traffic between the two segments without having to use the route add statements on the hosts?
