Silly (semi-related) question, but I (hope) you are not installing a default to ppp0 on your *nix box when the session comes up, or if you are, you have a static via your main nic to the l2tp endpoint address, else you will cause the tunnel to fall down due to recursion. Dave.

Dave, Negative - the ppp doesn't even get to IPCP stage and defaultroute is not turned on. On another note, I tested a cisco and the LAC and it's working fine with the same config so must be something with pppd/xl2tpd. I've used this config before with l2tpns but never tried with IOS before.

Chris, Thanks for your suggestion but I originally had ppp mtu adaptive on. The PPP negotiation does not even seem to get to the MRU negotiation phase at all. The cisco seems to send an AuthAck but then a TermAck straight after it. Pat Tue, Oct 13, 2009 at 03:04:48PM +0200, Christophe Lucas
