can you make sure on server B you don't have any static routes for 192.168.3.0/24? The LTM should forward everything; do you have a virtual forwarding server defined (we have one for all addresses and ports, I think by default one is defined). You could also try running some tcpdumps to see if you can determine where the issue is.

 

 

couple of questions:

 

- what are the default gateways for servers b and c?

 

- do you have any SNATs configured (or are using automap)?

 

- are there any switches in your env that are plugged into all VLANs as well?

 

 

 

The last one could cause you an issue. For instance, let's says that Server C's default Gateway is Switch1. However, Switch1 has interfaces on both 192.168.3.0/24 (call it int1) and 192.168.2.0/24 (call it int2). This would lead to asynchronous routing...
