Performance layer 4 VIP for SMTP not balancing
Hi all, I'm really stuck on an VIP that's not balancing at all. We have performance layer 4 VIP 10.x.103.49 with a SNAT of 10.x.104.49
It has 2 pool members that are up using a SMTP monitor and the VIP is up. However when I do a TCPdump I see the client trying to connect and the traffic just disappearing. No balancing, no traffic from the SNAT address to the servers.
I can telnet to the servers from the F5 on port 25 and get a response. It just seems like the F5 isn't trying to forward the traffic at all.
To muddy the waters there is an identical (at least I think it is) VIP that is working fine.
Any advice would be greatly appreciated.
Thanks
