We currently have 5 sites using hardware VPN equipment (Nortel & Lucent). We have some remote users that need to be able to attach to our VPN via the Internet because they do not have permanent locations for us to drop lines to.
For the most part, our company is 95% Windows 2000 including the servers and workstations. We have a handful of Windows 98 machines. The VPN hardware translates our private 10 dot network between the sites over the net. Our firewall is also configured for many-internal to one-external IP, FYI.
The problem I have is I was trying to use the built-in PPTP/VPN solution in Windows 2000 Server for my remote travelling users. This require port 1723/ip and port 47/udp. 1723 is not a big deal, but our VPN equipment basically reformats anything coming in port 47 for it's own use so software PPTP dies after authentication from an outside PPTP session.
My question is if anyone knows of any other software VPN solution that I can use to get around this. I desperately need to get remote users in and can open up ports on our firewall if needed. The software needs to be able to support NAT'ing. Thank you -very- much!
