HI, MY win95 clients access a samba server, that connects them to the internet via dialup, too. The linux-box is dialing unnecessarily when win95 is trying to get information about servers around. Which port do i have to forbid??? More important (because I can find out the TCP/IP port): How can i forbid forwarding/masquerading for a specific TCP/IP port (kernel 2.0.35) thanx florian attenberger
