Hi Brad,

 

 

I would have guessed that you don't have SNAT enabled and the server's default gateway is pointing to something other than LTM. But apparently you have SNAT enabled. Can you use tcpdump to check what's happening on the client and serverside connections? You can check SOL411 for details on tcpdump. If you need help analyzing the output you can open a case with F5 Support.

 

 

sol411: Overview of packet tracing with the tcpdump utility

tcpdump -ni 0.0 -s0 host 1.1.1.1 or host 2.2.2.2

 

(where 1.1.1.1 and 2.2.2.2 are the client and server addresses)
