[pptp-server] Can't Ping a Thing

[Angilberto Muniz Sb]

I would guess that you have created a win98 dialup entry end let win98
adjust it by itself -- as default, win98 sets up a default gateway directed
to the link.
Try 'unclick' the "use the remote gateway" options on the Propriety section
of the VPN dialup entry...
