Ipfwadm is the tool for IP FireWall ADMinistration. With it you can tell it not to accept certain IP packets, and to block forwarding. It's possible that forwarding (i.e. passing packets from one interface through to another) is turned on by default, so that if your win95 system does a broadcast for netbios, that gets sent to the isdn interface, which triggers a dialout. Try "ipfwadm -F -p deny". That tells the kernel not to allow any forwarding (forwarding default policy is deny). For more info, look at www.xos.nl/linux/ipfwadm/ . You can also check what IP packet is causing the dialout; debian isdn config by default logs the first outgoing packet which triggers the dialout, look in /var/log/kern.log for lines like: Sep 2 19:39:39 janux kernel: OPEN: 194.109.102.29 -> 194.229.27.42 TCP, port: 15907 -> 21 This shows that the packet originating from IP 194.109.102.29 going to 194.229.27.42 on tcp port 21 is causing the dialout. Port 21/tcp is ftp according to /etc/services, so here someone typed "ftp ftp.nluug.nl" (194.229.27.42 is ftp.nluug.nl). This information can help to track down what the problem is. > is doing it. I've also heard that turning DNS lookups on or off on the win95 system can help...
