      Hi All,

      I have a Video/Voice server sitting in my environment, I can make outgoing calls and UDP connections are fine (Voice/Video from my units are reaching remote destination) but the traffic from the remote destinations are being dropped.

      I setup my server to have a virtual IP that was provided from my ISP, created a 1:1 NAT Rule and opened the following ports:

      • 5060

      • 5061

      • and the Media Port range the server is using

      First 2 are TCP and the last is UDP.

      Initially, looking at the logs in the firewall rules, outgoing UDP ports were being blocked, but I enabled that. But I can't seem to figure out why incoming UDP ports from my WAN interface is being dropped.
      I even did a packet capture on the interfaces. I see the UDP traffic hitting my WAN interface, but when I run the PCAP on my Internal Interface, I don't see them.

      Oh, I forgot to mention, I also created an outbound rule for traffic to from that server to only go though my public IP. So not sure what is going on. I've seen a bunch of forums but none are really helping.

      Any ideas are welcome :D

      Regards!
