[44net] ax25 stack on Debian 11.5, kernel 5.10.0-18

Greetings. Lately upgraded my Debian server in two steps: 9.13 to 10.4 then to 11.5 ax25 stack seem to be running locally O.K. "ip route show table 1" command prints bunch of routes. JNOS2, URONode and FBB BBS communicate locally with each other O.K. But there is no data flow with outer 44 world, unfortunately. Suggestions and help to resolve this issue will be very much appreciated. Best regards. https://www.sp2l.ampr.org/ -- Tom - SP2L ------------------------------------ It is nice to be important.
