Port redirect on return traffic
I have a situation where the client network will only allow port UDP9010 through the firewall.
The scenario is a device connects to a VIP on the F5 using UDP 9010 and needs to have the response directed back to them on port UDP 9010. Since the F5 will try and send it back based on the clients source port (random ephemeral port), I need to find a way to change that port to 9010. Since this is UDP and therefore connectionless, as long as the response is going to the correct IP, I don't need to maintain any kind of state.
I posted this in the iRules forum as well, but thought this may be a design question.
Not sure if an iRule or possibly using a L4 forwarding scenario for outbound traffic would work, but I haven't been able to find a good solution.
Any help is appreciated.
Thanks,
Mike
