Hello John,
I am by no means an expert on this ax25ip, but I did set it up here to
learn and test it, and found during testing, that some rules weren't so
apparent. I found the file, README.ax25ipd to be most informative. It
is in the source files, /usr/src/ax25-utils.../ax25ipd/ dir. The text
also contains some typical setup configs. I have included here, a brief
snip of one of the eye-openers that may be overlooked when testing and
configuring.
...from README.ax25ipd:
Modes and Routing
-----------------
There are two interfaces into and out of ax25ipd. The KISS interface
is a standard serial port, running speeds up to 38400 baud. The IP
interface reads and writes packets to an IP network in accordance with
the specifications in RFC1226. Several factors determine how AX.25
frames route within ax25ipd and through the IP network, although some
basic rules always apply:
A frame will never leave ax25ipd on the same interface it came in on.
This fundamental rule eliminates much complexity and much confusion on
how to set up ax25ipd.
----------
Thus, if a frame is received on your pi port, it must leave on a
different port.

In axports, you need to declare the axip port itself, and probably waste
another ssid. Or, you may be able to assign it something like ax8apr-7,
with periodic legal ID in the beacon text.

See the above reference to in and out ports...
