winnt 4 box w sp2 and ms proxy server 2.0

fresh install on both , 2 nics both able to c respective networks, internal and external. MS Proxy server wont route across box however. when I go into the internet services manager under web proxy andsocks proxy the security button informs me that routing is not ppossible becasue there is no external nic available.

i have populated the LAT with the internal addx and ip forwarding is turned off 4 both. default gateway is on extrenal NIC only not internal

and still cant route across box. I have a working proxy server and have compared all settings and all r same

this is really got me stumped

Try changing your http port designation on IE LAN connections, proxy server from port 80 to port 8080. If you can connect to the internet via IE throught proxy server on port 8080 then port 80 is being used by IIS service. That is usually the case when using proxy server for internet access.

Another problem you might have whereas NT doesn't see the second NIC as an external interface is that it's range IP address is listed in the LAT. Try removing that range of IP address for your WAN NIC.

here i am using isa server .it need internal external card to be assigned via firewall properties.check wether the external ip address included in the LAT table.
or
you can add routing via route ADD dos command

There is a rare bug in NT where you may have problems if the external TCP/IP settings are bound to the second nic card. If you go to Network Properties -> TCP/IP -> Properties, in the dropdown menu for the NICs you will see them numbered (1) and (2). The 1st nic should be configured as the external card, and the 2nd as the LAN card.

Hope that helps.
