[TriLUG] help setting up Nextel BPL modem under Linux

[Aaron Joyner]

Well we did some further testing on my laptop last night at the TriLUG 
meeting, and the setup really is quite odd.  It seems that his static 
IP gets assigned to the local interface, and a static route to a MAC 
address gets assigned to the ethernet card - although I don't quite 
know how DHCP is setting that up.  Unfortunately, time and reception 
didn't allow us to slap tcpdump on the interface and log the DHCP 
traffic, but perhaps someone can reason out how DHCP would define that. 
  I'm including a copy of the routing table that was on my Mac while it 
was connected via DHCP, for reference purposes.
