On my system i use axip and axudp. I start ax25ipd twice with different configuration files.
Example for a axip port
Start
ax25ipd -c /etc/ax25/ax25ipd-axip.conf
# ax25ipd configuration file Axip # socket ip mode tnc mycall pi1lap-9 device /dev/ttyq3 speed 19200 # # loglevel 0 - no output # loglevel 1 - config info only # loglevel 2 - major events and errors # loglevel 3 - major events, errors, and AX25 frame trace # loglevel 4 - all events # log 0 for the moment, syslog not working yet ... # loglevel 2 broadcast NODES route n1uro 44.x.x.x b route pi1bdg 44.x.x.x b
