Hi all, appreciate some help on a one way audio issue.

Have port mirror on and using wireshark on WAN and LAN port.

SIP is establishing and ending fine, the issue is with RTP coming in WAN side.

Can see the RTP packets coming in on the WAN interface but they aren't leaving the LAN interface. The other direction for RTP packets is fine.

We currently have udp ports open for 6000 to 40000.
