Oh, so you are routing from one netrom port to the next ? No network cable on your
computer ? Doesn't really matter, I am just wondering and trying to understand the
structure of all this. Oh, read that on4ufa is indeed on the Net (dah, that's where
I sent this mail too... Reading really helps...).

My fault. Didn't notice the different call, meaning hardware-address in this case.
I am too used to 12:34:45:78:90:12 Ethernet MACs...

Ok, looks good. Sorry about the confusion. So netrom is point-to-point in this
case ? Man, maybe more complicated than I thought. Hope I don't confuse more then
I help...

Ah, so that net is 44.144.9.0 ? Netmask looks ok to me, I hope I remembered right...

Can you do a "arp -an" and mail the results ? Since the 44.144.9.13 can reach
44.144.0.2 but not 44.144.0.1 (right ?) can you also mail a "route -n" from
44.144.0.2 ? I still suspect a TCP packet pile up somewhere. Hm.
