currently we have an environment where all our hosts are connected to an adtran 1638 stack. our network is 172.16.X.X/16 . hosts on this network cannot reach a remote host of 172.16.34.X/24 they can reach host at 172.16.32.X/24. We believe the routing table on these adtrans is causing traffic meant for the 172.16.34 network to hit a router where it is being dropped instead of going to a firewall address of 172.16.1.252. routes are: 172.16.0.0/ 16 next hop 0.0.0.0. Connected and 0.0.0.0 / 0.0.0.0 next hop 10.10.0.1 Connected. I think what is happening is the 172.16.0.0 route is sending traffic for 172.16.34.0 to a router instead of to our firewall where it should go. how do I correct this? i've tried a static route but this connected route seems to override it.
i should note that the 172.16.34.X/24 network is accessed via our firewall because it is a site to site VPN connection that is the first we are setting up on this network.
all the other 172.16.X.X / 24 remote networks are behind a router attached to an MPLS network.
