The problem is of rou= ting entries. =A0 Just add default route at your=A0node 10.225.162.28, and make the default G= W for this route as =A0192.168.28.0/24 or the connected interface. Your SRV= node should pass it to its default gw 192.168.28.1 which should take care = of forwarding it to the destination RN. If your SRV node could forward the = ping reply then add a specific route there like - "pkt comes from=A010.225.= 162.0 then forward it to 192.168.28.1.

I don't think, because your SRV is looking for its gateway, but never get a= n answer from it. It's subnetmask is to small to reach another subnet. Put another network card in it with an ip of 192.168.28 and all will workin= g.
