GREETINGS:
I have an extension that registers when connected to my LAN, but not from the WAN side. I initiated a debug by IP. I get the following results with an authentication failure resulting in the registration attempt being torn down.

On my firewall I have opened ports 5060,5061 for sip and rtp ports 10000 to 20000, but none of these entries are being used because I do not see any hit counters are incrementing.
The remote device I am using is a linksys PAP2T ATA
