Hello Guy !
Hold on a second. on4ufa.ampr.org is 44.144.0.2 on Ethernet, right ?

> /sbin/arp -H netrom -s 44.144.90.5 ON4AAK -i nr0
This assigns 44.144.90.5 to the netrom port, meaning you are 44.144.0.2 on Ethernet
and 44.144.90.5 on Netrom.

> /sbin/route add -host 44.144.90.5 dev nr0
This means that you can reach 44.144.90.5 via nr0. But 44.144.90.5 is 44.144.0.2 is
the same machine ? I am not into Netrom but in Ethernet this would mean that I
send stuff for myself in the Ethernet, where the router sends it right back to me,
then I sent it back in the Ethernet etc. Sounds like a loopback to me...

> /sbin/route add -net 44.144.9.0 netmask 255.255.255.0 gw 44.144.90.5
This means that I can reach the 44.144.9.0 net via 44.144.90.5 which is on4ufa !

I would guess that we have a pile up of packets somewhere. Could you elaborate what
IP-addresses on4ufa has, whether there is one station or more station on the other
side of the Netrom connection and from where packets should go where ?

I am not much into ham but I have messed with routing quite a bit so we should be
able to figure this out. Either the ARP entry or the first route is wrong.

Jochen
