Microsoft Proxy/NT Configuration

By keatingj ·
i would like to have a really good example of configuring a NT Server Box with two NIC cards to be a proxy server. Issue 1: The real IP address 198.x.x.x assigned to NIC 1 must be able to communitcate with three servers and a WAN that does not reside behind the proxy. The second NIC with the IP range of 10.x.x.x will be used for client machines. The clients must be capable of logging into an Exchange server residing above the proxy as well as receiving the login information from a PDC. Problems: Not sure if WINS is an issue here. NIC 1 has the real IP address and the gateway. NIC 2 uses 10.x.x.1 and has no default gateway. When I install the proxy client on a client machine I do not get NT login validation. I am able to surf the web so proxy appears to be routing web pages but not network browse functions. If anyone has some advice on directions or needs further information to provide an accurate response please let me know.

Thanks in advance.

Not sure what your getting at, but i have this set up.

Proxy with 2 nics

nic a has IP for the external network
nic b has a 168.23.x.x which is a subnet off a router

the whole wan/lan uses the router to feed the proxy requests to nic b.

this way, its nearly impossible for a Internet user to route back to our wan/lan via the nic a.

I don't think you have a problem with your Proxy. I guess it's only the workstation's problem. Logging on to the domain, if you are using Win95/98, needs to be configured right. Right click network neighborhood, add Client for Microsoft networks.Double-click Client for Microsoft network, it says there Logon to Windows NT Domain, type the name of the domain name of the PDC. This will let your clients be authenticated by the PDC. Make sure client computers are on thesame subnet. Use thesame gateway for all the clients, this is important.

Also make sure that you have put a workgroup on the Identification tab, making it a member of a certain group. If everything's setup, i don't think you'd have problems browsing your network.

Aboutyour Exchange server, for the workstation to be able to relay mails to it outside of Proxy, on the configuration of your client make sure you put the IP address of the Proxy on the "Outgoing mail or SMTP".

Good luck....

You might want to check your permission's on Web Proxy and WinSock Proxy and if your using Socks proxy. Start the Proxy MMC and right click on Web proxy then select properties after the properties screen comes up go to the permission tab, see if youhave checked the enable acess control box if this is checked you won't be able to get a NT logon validation until you set your permissions. Hope this helps

check the LAT ( LOCAL ADDRESS TABLE ) IN THE PROXY SERVER CONFIGURATION . Check whether u have given all internal ip address range that you are using and no external ip address range exists if it exists then remove them .
second to use the security feature for the proxy u have to enable the Access Control from the winsocks configuration and the socks configuration and then u have to give rights to the users whom u want to allow access and it will ask for the NT password as soon as the client machines opens the Internet explorer

hope this helps

(I think) you're clients should be using your Proxy server as their default gateway.

The rest of it sounds ok.
