Hi

 

Pool member is always ip:port combo, so whether you change the ip, or the port should make no difference, each one is a unique instance. Since you are using SNAT automap ( I assume your monitor is showing the members as UP -use at least a TCP monitor to be sure-), does the F5 have an IP address in the same broadcast domain as the pool members' IP address? - Please ensure no firewall issues if not...

 

Make sure that your virtual server has BOTH IP and port translation enabled as well (since you are running the same application in multiple ports on the node, this is almost certainly necessary).

 

Lastly, if all else fails, disable ALL but one member in the gui, and then run a to see the traffic going through in a shell on the F5.

 

Good luck.
