I've got an NT server (v4.0 sp4) with Netscape proxy 3.5 installed. I have 2 NICs. NIC 1 has a public IP address, ie 188.8.131.52 and connects to our ISP's router, while the NIC 2 network is using a private, class C address scheme, ie 192.168.x.x
The proxy server is quite happily proxying HTTP and FTP, but some of the clients on NIC 2 need to use telnet and pop3 email. I've tried enabling SOCKS5.0 on the proxy server, but it still doesn't let me telnet etc or even ping.
I can ping NIC1 from a client on the NIC2 network, but not any other address on that network.
