This is a mystery to me too :)

I have found the problem. I can't say for 100% that everything is OK,
because I must do some more testing (over ADSL, cabel, GPRS, ...), but
now I can use a roadwarrior client AND the static tunnel - so far
withtout problems.

The problem was in the MTU and MRU setting in options.l2tpd. First my
settings were :

[root at rikom ppp]# cat /etc/ppp/options.l2tpd
+mschap-v2
ipcp-accept-local
ipcp-accept-remote
ms-dns  192.168.15.1
auth
idle 1800
mtu 1410	*
mru 1410	*
nodefaultroute
debug
lock
connect-delay 5000
[root at rikom ppp]#


Now they are :

[root at rikom ppp]# cat /etc/ppp/options.l2tpd
+mschap-v2
ipcp-accept-local
ipcp-accept-remote
ms-dns  192.168.15.1
auth
idle 1800
mtu 1300	*
mru 1300	*
nodefaultroute
debug
lock
connect-delay 5000
[root at rikom ppp]#


I have NO idea why the roadwarrior setup was working OK before I have
added the static tunnel and why it stoped then... But, for now
everything is working as it should with the new MTU and MRU settings.

Many thanks to John and others,
