Okay, first, to clear up a few misconceptions. The Nextel service is not BPL based. It's a 3G (3rd Generation) Cellular Network, in other words it operates in similar spectrum and off the same towers, as the regular Nextel Cellular service does. So don't worry, your 10m band will be fine. :)I've got this modem working with the CD provided for windows and am now trying to get it run under Linux.
You are precisely correct in that the "broadband modem" you have is just a bridge. Also, if you're using the Static IP based service, you *probably* shouldn't be getting your address via DHCP. You'll need to get a gateway address from Nextel that corresponds to your Static IP subnet - if I had to hazard a guess I'd bet on 65.76.244.254 or 65.76.244.1 Try setting your gateway to one of those addresses, and see what you get.
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. So uncommon that in my 8 years in the ISP industry, I've never seen it done. 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. What you'd need to setup in Linux is something like this:
# route add -host 172.29.251.133 dev eth0
...Which would give you something like this...
# route
Destination Gateway Genmask Flags Metric Ref Use Iface
172.29.251.133 * 255.255.255.255 UH 0 0 0 eth0
At which point you'd be able to add 172.29.251.133 as your default gateway.
Other, sneaky yet valid, options - try nmap'ing your entire subnet. See what IPs respond, and try setting your default gateway to that IP address and pinging out. :) Check out "arp -a" - see what addresses end up in your arp traffic because they happened to be on the other end of the bridge. Try setting your gw to those.
Above all, let us know what you come up with - I'd really like to hear. Also, if you want further help, I'll be at the meeting tonight w/ my working Nextel broadband connection. :) The only difference being that I don't have the static IP based service.
