My restrictions are the following: 1- I need to set the vpn server on windows XP (not windows 2000 server, nor 2003, nor ISA server, etc.) 2- I need to use tunnel mode ipsec 3- The vpn server should accept MULTIPLE vpn tunnels. The first problem I faced is that windows xp does not support ipsec tunnel mode between 2 xp machines. It only supports transport mode which is not what I want. To overcome this lack of IP tunneling I tried to use the built-in tunneling capabilities such as PPTP and L2TP/ipsec, and it worked. But the problem here is that a windows xp can not accept more than ONE SINGLE incoming connection at a time, and I need multiple connections. I think the solution could be one of the following: 1-Installing a third party FREE vpn server (or L2TP server) on windows XP. If you know one please tell me. 2-Importing some features from windows 2000 server or 2003 server (some executables or services or plugins that enable xp to run as a vpn server and accept multiple connections). If you know what to import please tell me. 3- Installing a pure IP tunneling solution on windows xp so that it can be combined with ipsec encryption to yield tunnel mode encryption. I appreciate any help, Alaadin _________________________________________________________________ Express yourself instantly with MSN Messenger!
