Re: [suse-security] PPTP VPN Connection Windows XP client - Linux Server

This is _not_ a good idea. All professional VPN software I know prohibits

client for linux does that! Most VPN clients also contain a small personal

the VPN, tell them to use the proxy in your company.
Well, I don't think, this might cause any problems.
First, the clients are behind a router and
second, Windows does no forwarding by default.
When talking about the classical roadwarrior scenario, where a single
remote client dials into the internet and then starts the VPN, I would
agree that this might include some potential danger.
We are talking about a rather complex scenario where different clients
at different locations behind (almost NAT-) routers with ADSL
connections need a permanent VPN link to a central system mainly for
voice over IP purposes. If the complete internet traffic of the remote
clients would be routed through the ADSL connection, the bandwidth for
VoIP would not be satisfactory. Besides the additional traffic cost... I
myself would prefer to just replace the consumer style routers by
professional VPN routers, put a static route to the remote LAN and a
don't-forward-rule on and there we go. But the customer is not willing
to pay e.g. a bulk of PIX 501 for the employees' home offices... So I
have the fun to construct a working, secure (kinda) and
