Hello,
i try to connect via L2TP a Win xp Pro client with a linux server (ipsec
disabled, no authentication). Very often i get the "loopback error" message
on the xp client (but i have already "connect-delay 5000" in the ppp option
file).
Now i have logged the telegrams at the xp client and i have seen, that
really during connection startup all send packes are echoed (see log
file)...
I this correct? I think not...
What could be the reason for this?
XP client: 192.168.229.1
Linux server: 192.168.229.10
No. Time Source Destination Protocol
