Easy, several of us here are using it for a CM firewall now. Just put two NICs in and connect one to the CM and the other to a hub so you can NATd and such. As one guy puts it: "Let's go see what's interesting on Cable tonight". tcpdump and connect logs will quickly demo why you want some kind of firewall. Most of the cable subnets use DHCP, but rarely change addresses so you can either use the DHCP w/FBSD3.3-R or get the DHCP port or just fix the address in /etc/hosts and /etc/rc.conf, depending on your time. Subnet masks have either been 256 addresses or 1024 addresses per subnet here. If you use ipfw to block 'ping's, you will see many fewer attacks. Works great with ADSL as well - Jy@ On Mon, 18 Oct 1999, Daniel O'Callaghan wrote: > How hard is it to connect to a cable modem service with FreeBSD? > I'm thinking of getting a Foxtel connection, which uses the Motorola > 10Mbps/768kbps system. > > Danny To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
