Description (partial)


Traffic destined TO the ASA fails with a route lookup problem. Traffic THROUGH the ASA works fine. The diagnostics is:

%ASA-6-110003: Routing failed to locate next hop for TCP from out2: to out2:


%ASA-6-110003: Routing failed to locate next hop for udp from NP Identity Ifc: to out2:

depending on the ASA version, configuration and protocol being used.


Configured a default gateway on one interface and a second default gateway on another interface with a higher metric. A client connects to the ASA second interface via ssh, telnet, VPN, etc. Depending on ASA software version and other conditions some of the protocols may work and some of them do not work, but this is not a supported configuration anyway.

This problem did not happen in PIX 6.3. It was first noticed on ASA 7.x.
