I have a costumer that is using a Windows 2003 Server behind a firewall running PPTP and L2TP for the costumers branch officess to connect via Lan to Lan VPN using Windows servers, now the costumer is setting up 2 new sites and we convised the costumer to go for Cisco 831 instead of using the server as the VPN server on theese sites, however we can't replace the Windows VPN server at the head office yet and we need to set up an Lan to Lan VPN using L2TP or PPTP from the Cisco 831 to the Windows 2003 server, in one site the Cisco will be placed behind a NAT device from the ISP so this will mean NAT-T.
Any ideas if this will work and how?, any examples ?
Thank's Yes i have already read that one that one however describes Client to Server VPN not Site to Site, so the question remains can the Cisco 831 acts as a L2TP or PPTP VPN server for site to site VPN tunneling with a MS Server ?
