Hi,
I'm running microsoft proxy 2.0... On a winnt4.0 server.
Is there a way to see a listing of what ports are open and what is assigned to them. Also I have to open ports tcp 50,51 also port tcp 500.. As I understand I have to check "Enable Packet Filtering on external interface" and also Enable Dynamic Packet Filtering of Microsoft Proxy Server Packets". As of now neither one of them are checked, and right now our internet access is working fine. If I do check the above and add the ports above will that effect the current status of the internet for the users.I hope I explained this right. Any help with either question would be appreciated.

I do not believe that you need to check those option, but I coul dbe worng.

To open a port in proxy you simply need to go to Internet Infomation Manager snap-in and right click on socks proxy and click properties. Next go to the tab for permissions and you should be able to add protocols (and ports.

For example if you need to add FTP (21) you would create a new protocol named FTP and assign port 21 TCP inbound to it. You then can go to security and then in the drop down box select FTP andassign Access rights.

I hope I remembered this right and I hope it helps!

Based off port numbering, it seems to me that you are trying to setup some sort of VPN. Am I correct? If I am, I don't understand what the proxy server has to do with it. Are you trying to proxy VPN clients?

More specifically, why do you need these ports open? What is it you are trying to accomplish? If it is for a VPN, what VPN client/server are you using, and what problems are you having?
