Routing question

Do all of the routers on the LANs that you are attached to know how to get
to BOTH of the CIDR blocks that you are part of? If not, then you could
say that the LAN routing is broken, or you could say that you need to
insure that when a packet leaves one of your interfaces that it has that
interfaces IP address in the source. I bet tcpdump (or equiv) will reveal
your issue(s) pretty quickly.
