Progress.

For your reference, Verizon 888-553-1555 is supposedly Tier III suport for the Actiontec M1424WR router on my FIOS system.

Their first response to why PP and Tracert work on RoadRunner and not FIOS is "Its a firewall issue." After a little pushing they decided it was THEIR firewall, the one built into the Actiontec M1424WR router.

They suggested I contact you and find out if your program uses PCP or UDP and get back with them to have them help me setup the router to use Port 40.

This is a little over my head, but i'm hoping the Verizon FIOS market for Pingplotter is big enough you can afford to help me <img src="/forums/images/graemlins/smile.gif" alt="" />
