- Sat Apr 11, 2015 9:58 am #14184 This would seem to be an issue for anyprotocol carried over UDP, where the ESP would send from a port, then interpret a response delivered to the same port.

I've documented this issue (regardless of localport specified, the outgoing traffic goes out a dynamic port) on the git repo, it is easy to confirm with a network sniffer.
