You can do this one of two ways:

        - run a SOCKS proxy on the Linux firewall and then
          install and configure all the client software to
          use the proxy

        - enable MASQ on the Linux firewall.

Hi all,
  
I have been using with success masquerade in the "correct way" ... i mean 
  
    no official ip ------- Masquerade Box ------- Internet
  
But this time the problem is different, i have this situation
  
---- 172.x.x.x network----| Cisco Router |--isdn--| Cisco Router |----
193.x.x.x network ----| Linux Firewall |---- 173.x.x.x network ----| Cisco
Internet Router |---- ?? Internet ??
  
I wanna user of the 172 network to be able to reach the Net. The Cisco IOS is
not IP+ so i couldn't do NAT with the Router.
The address between our Firewall and the Internet Cisco Router ar unofficial
... so this time i try to masquerade using the internal address of our Linux
Firewall (wich is official) but without succes.
Is there a way to force the masquerading using the IP address of the internal
NIC ? 
  
Thx,
  
Olivier
