I have a client with a Linksys router befsr81, port 1723 forward to static IP with Windows 7 VPN Server setup. VPN Pass-through is enabled.VPN Client is Windows 7. From inside the network everthing connects fine (same 192.168.1 network). When I try to connect via my cell phone over the internet I get "verifing User and password" and it stops. When I look at the Router logs I see my clients IP address going to the server static IP port 1723. i.e. TCP from 99.99.99.99:3137 to 192.168.1.50:1723 where 99 is my IP and 192.168.1.50 it the static IP of the VPN server. The Server PC has Mcfee but I did not need to make any changes when I connected internally.

First, a Linksys BEFSR81 is an ancient consumer router. It is not a viable business router. So it may be at the root of your issues.

Second, connecting via cell phone introduces a double NAT arrangement (at least probably does) and I do not know if built-in Microsoft VPN can navigate that setup. NCP Secure entry IPSec can navigate it, but that requires different equipment.

I would start with a much more modern router and go from there.  ... Thinkpads_User

This is a residential client not business, I did test an Linksys e2000 with the same results.

Thanks. You are probably grappling with the cell phone issue I described above. I would try a new newer router and a wired external connection (not cell phone) and see if you can make it work. Windows 7 is vastly different than earlier systems and may still give you some issues. ... Thinkpads_User
