Something like: ifconfig_dc1="inet 10.0.0.1 netmask 255.0.0.0" That gives you a "slash 8" network starting at 10.0.0.1. The /8 means that you only use 8 bits for the netmask, so only the first byte is 255. What netmask 255.0.0.0, or /8 means, is that you have the other three bytes of the reserved /8 10.net for your network, so your Win2k box could have most IP addresses between 10.0.0.2 and 10.255.255.254. > the freebsd bot is online but i have no idea how to connect my win2k pc to > the net using the freebsd as gateway. > > i'd appreciate it if someone can help me. Please, to RTFM. Once you think you've gotten most of the way there, and you still can't figure out what's broken, ping us again. The NAT setup can be tricky, even when you think you understand what you're doing. As you debug things here, use ping. You'll have weird combinations of firewall rules, NAT, and plain old TCP/IP configuration to figure out here. :) Good luck! -danny To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
