you know I thought I had this cracked when I finally figure out how to turn on the UPnP on my router and re-checked to make sure its still active which it wasnt before.

I changed the setting back to UPnP in LM the port says 62000 not sure if thats still good.

Still LM says im stuck behind a firewall..

you mentioned "even though you only use it as a modem ... I have a suspicion it may well have an internal NAT firewall."

how do I check this out to be true and how can this be true if its never been an issue when I had LM in the past?
