I'm new to this forum, so please be gentle !

I need to get my IBM RS running AIX4.3 onto the internet to a particular ftp server, through a NT server running proxy services.
This NT server is directly connected to our internet router vis a secondary NIC on the NT server.
When I add the route to the destination ftp server via gateway ip of the NT server, I get destination unreachable.
Is the fault with AIX, or is it NT. Iread somewhere about SOCKs not being compatible, but not sure if it means SOCKs on NT.

Hope that's enough info for you gurus ?
