Nimbostratusspecific source port translation
Hi,
I am trying to do SNAT while selecting a specific port for that but for some reason when the F5 receive the response it is sending a RST to the WS and not retranslating it to the original IP...

EmployeeI didn't exactly understood how you can determine which TMM will handle the traffic when the traffic return to the F5 and not leaving it.. it is source port XOR destination port MOD total number of tmm instances.
for the irule, i think TCP::unused_port may be useful (because you have to select correct snat port and it must be available to use).
