outbound VPN's fail (pptp/l2tp/ipsec)
Hi there.
Fist of all, I did google for it, but I only get results that don't match my config.
My situation is as follows:
1.1.1.1 <----------> 2.2.2.2 / 172.0.0.5 <---> 172.0.0.6
Pub. VPN Server [FC6 Firewall/Router] WinXP SP2 Client
The FC6 router does the NAT etc. with IPTables for the internal 172-LAN.
The problem is that I can't connect to the public VPN server from my WinXP Client. For now I tried around 20 combo's of IPTables rules to get the VPN working but I failed in all ways.
On the client I tried it with the default windows VPN client and also with a third-party IPSEC-VPN client, but just no go.
I hope someone is willing to help me out with this?!
All the result I did find on the internet are based on the situation that the VPN-Server is behind an IPTables firewall. Which is not the case with me.
TIA.
Onno.

are you connecting from the inside or the outside ? Your diagram seems to indicate that your winxp client is on the lan.

Hi datopdog,
I'm connecting from the inside (172.0.0.6), the XP-Client is indeed the connecting client.
Hope you can help me!
Thanks!

Look at your system logs on both sides.
Use a tool like ethereal to monitor the traffic. Although you can't read it, you can see who's talking to whom.
