config: 1 linux 7.3 server with Elsa MicroLink ISDN 5 win nt 1 linux server for test and development i want to permi the users of the intrant to: - navigate in inernet with squid as proxy (works just) - use their windows mail-client (pop (110) and smtp (25) via the linux server having all the same provider (the ippp-connection has the same provider like the user mail-accounts - activate a fax-server for all users (hylkafax?) - avtivate a dial-in server questions: - it's neccessary to use send/fetchmail for a mail-forwarding or can i open with iptables these ports for unfiltered input/output/forward? - how i must set the routing on the linux servers, that all users use this gateway? it's impossible to make a static gateway, because the provider gives always a dynamic ip address i'm a very beginner in routing, and all my tests changing the routing table make deasaters - just more than one time i must re-install all for make the server workig in the last state .... thanks in advance roland
