I really didn't have a clue, but I'd heard that it was BPL.

I had assumed it's hardwired into the modem, but if it's 3G Cellular, I have no idea where the dhcp server is. > Bottom line, from a purely networking perspective, you can't have a > default gateway that a) is not on your local subnet or b) you don't have > a static route to --- and b is really uncommon. yes, I understand this :-) > So uncommon that in my 8 years in the ISP industry, I've never seen it > done. it may be mathematically impossible > So let's hazard a guess that your default gateway really is accessible > on the other side of that connection, and you can send it traffic > directly.

I did have something else planned this evening, but if I don't get this running this afternoon, I'll gladly come along. Will you be wearing a red rose in your lapel and hopping up and down on one foot? I'll bring my nextel modem, and plug it into your machine if that's OK.
