[pptp-server] Special routing requirement for pptp?

[G. Georgiev]

	Hello,

	Sometimes I am unable to establish the pptp link for hours and I
wonder if the problem is not with my ISP provider - it looks as if the
remote end does not reply to the LCP ConfReq. If I forwad the connection
over another line (modem) it will work. On top of all most of the time it
works over the cable (my regular internet conection), but it happens to
fail for many hours.

	Is there any special requierement from my ISP for the pptp link to
work? I remeber that there was some particularity, byt forgot what / where
I read that.

	And how I may check exactly on which router the link is broken?

	Thank, George.
