    I've been attempting to implement SDLC STUN with limited success. With
    local acknowledgement turned on I get an SDLC error in the debig and
    it doesn't work, turn off local ack and it bursts into life.

    Can anyone shed some light on this?

    stun peer-name 10.4.201.10
    stun protocol-group 1 sdlc
    stun remote-peer-keepalive

    interface Serial0/1
    mtu 2104
    no ip address
    encapsulation stun
    serial restart-delay 0
    nrzi-encoding
    clockrate 19200
    stun group 1
    stun sdlc-role primary
    sdlc N1 521
    sdlc address 40
    sdlc simultaneous full-datmode
    stun route address 40 tcp 10.2.226.20 local-ack
    stun route address FF tcp 10.2.226.20
    end

    I then removed local acknowledgement and all started working ok
