We have a WinNT server running WinProxy 3.0 with a DSL router at our office. It's a small TCP/IP network. I would like to set up remote access between the office and the employees' home computers, and set up an FTP and web site from our server.
The DSL router unfortunately doesn't accept PPTP protocol, and we don't have a static net IP address. I can ping the work server from home, but can't get a response from it or log on. The same from work to home. Since we're a small branch office,our budget for that kind of thing is pretty limited for now. I haven't been able to get remote access to work so far, and am wondering if there is an economical workaround for these problems (and if so, what it is), or if remote access will have to wait?

Thanks,
Harriet

It would be helpful to know the make and model of your DSL router because that might be part of the problem and part of the solution.

If the DSL router has firewall capabilities, you'll need to open a couple ports to accomplish what you want to do. To support an NT logon, you'll need to enable traffic on ports 137-139.

Your DSL router really doesn't have to support PPTP as long as you can open the proper ports to allow it to operate. The tunnel is from the server to the client and to intermediate devices along the way (like the router), it's just a stream of TCP packets.

For further information, you might want to start on TechNet at article Q179442 and go from there.

regards!

Thanks for your help --
The router is a Flow Point SDSL router, 2200-12.
It's configured for IP w/NAT, static, DHCP not enabled.
I can set up proxy plugs at for those ports. Would that do it? I also have the password for the router. I don't know how to change the router config, but no doubt it can be figured out.

Most routers do not support PPTP. Fortunately for you, PPTP is not secure (well, the protocol itself is secure, but not Microsoft's implementation of it. Besides, Microsoft is replacing PPTP with L2TP). You should look into SOCK v5. It is an IETF standard (rfc 1928) and is gaining popularity because it supports both private and dynamic IP addressing schemes. I believe Microsoft supports this. You can check this site as well:

http://www.hummingbird.com/products/evals/index.html

They offer SOCKS v5 server/client software (the SOCKS v5 client for Windows 95/NT is FREE).

And since SOCKS operate at the session layer (vs data link layer for PPTP/L2TP or network layer for IPSec), it is more secure. Of course, since it operates at layer 5, it is interoperable with other lower level VPN protocols, i.e. PPTP and IPSec. More info can be found at:

Good luck!

Thanks for the suggestions. I'll check out those sites and get SOCKS v5. It sounds good!
