netscape win behind firewall/dns problem

[bertrandt france]

        here we are:

                             |---- SOLARIS server/internal DNS
                             |
       LINUX(RH 6.0/socks5)  |
INET-----FW/external DNS-----|
          /proxy server      |---- 'n' SOLARIS netscape clients
                             |
                             |---- 'n' IRIX netscape clients
                             |
                             |---- 'n' LINUX netscape clients
                             |
                             |---- 'n' WIN netscape clients

- I need my external DNS for my internet server.
- I need my internal DNS for my intranet server and my LAN admin.
- I dont want my internal DNS to resolve external adresses.
- I dont want my clients to use external DNS.
- I dont need my clients to resolve external addresses.

      But netscape seems to talk only in socks V4 mode (socks5
can also, but then it need resolved adresses, and dont talk
to the external DNS). No problem with unix clients : I just set
SOCKS_NS variable to the IP address of my external DNS, netscape
only then uses the external DNS,and all works fine.

.............. what about Windows clients ???????

PS : I already suggested to throw windows away, but my boss .....
PPS: I said netscape doesn't talk with socks5, is that true ???


        Thanks for any help.
