Problem talking to VIP from Internal Node

Are your VLAN101 nodes able to talk directly to each other? Do you see any traffic coming into the destination VIP?

 

 

While not as complex as your setup (i don't use route domains), if my nodes are on the same internal vlan and need to access each other thru their vitrual server, i use an irule on the virtual server to snat automap only if they are both on the same network. This fixes the problem of an asynchronous route where the return traffic is not sent back up to the F5 but to the requesting node directly, which is then dropped.
