Hi all,

We at on4ufa.ampr.org [44.144.0.2] have the following situation:
We are using ip over netrom to route a part of belgian ampr.org ip
We are using 2.0.33 + ax25-utils-2.1.42a + ax25-module14e +
net-tools-1.32alpha

following lines in rc.local:
/sbin/arp -H netrom -s 44.144.90.5 ON4AAK -i nr0
/sbin/route add -host 44.144.90.5 dev nr0
/sbin/route add -net 44.144.9.0 netmask 255.255.255.0 gw 44.144.90.5

44.144.9.13 can ping, telnet,ftp,... to 44.144.0.2
but as soons as 44.144.9.13 goes to for example 44.144.0.1 .... on4ufa
crashes complete!!
a ping to 44.144.0.1 works but as soons as there is a bit of data.... all
locks up.
The only thing you can do at that moment is switch off the computer...!!!

So the crashes only occur when there is data comming in/out via netrom and
going out via encap on the ethernet!!

Has anyone seen something like this?
Could the mss value play any part in this??

btw. optimize as router is switched on in the kernel. and always defragment
is switched on.

I already tried 2.0.31/32 but they had the same problem...

Any assistance would be much appreciated !!!!
