Yeah, the situation here is similar. But... my primary connection is the 
LAN one. So.. I have internet connection through the LAN interface.
And this way, "all other traffic" is wrong. Because it applies not only 
to the tunneled packets but for the normal web request as well. I hope 
it's clear now.
So again, it's obvious.
Defaultroute from tunnel overlaps the one from the LAN interface which 
is wrong for the routing of normal web packets.

Well, tunnel terminator on the remote side you mean? Well, from what 
I've read on google, Framed-Route applies to the client requesting the 
address alongside with the Framed-IP and so on...
So it'd be weird what you say, but that can be an issue.

So, is there any method for adding a static route on the XP side after 
setting up the tunnel?
