First, here's the relevant section in the handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/config-network-setup.html Now, for network connectivity to work properly, you need three things: The interface must have an IP assigned to it, you need routing information (usually that means that you need to set a default route yourself, routing for your subnet is configured automatically when you set an IP), and last you'll probably want to have a DNS server set. If you are using DHCP, you need this entry in /etc/rc.conf: ifconfig_rl0="DHCP" and everything should work. If you don't have DHCP, or you wish to check the settings you got through DHCP, do this: * You can see your current IP by typing "ifconfig". You can assign a new IP with "ifconfig rl0 18.104.22.168". You can automatically assign an IP on startup by adding the following line to your /etc/rc.conf: ifconfig_rl0="inet 22.214.171.124 netmask 0xffffff00" * You can see the current default route (also referred to as default gateway) by typing "netstat -rn". The line starting with "default" (or 0.0.0.0 on Non-FreeBSD systems) is your default route. If you don't have one, you can set one with "route add default 126.96.36.199". The IP you specify there should be the IP of your firewall or router. To make this setting apply on startup, add this line to your /etc/rc.conf: defaultrouter="188.8.131.52" Again, the IP there is your router's IP. * You can see the currently set DNS server by looking at /etc/resolv.conf. You can add DNS servers my modifying that file. A correct entry looks like this: nameserver 184.108.40.206 If these settings are all correct, and you still don't have connectivity, the cause is one of the following: * Your networking card is broken. Your Realtek card is of extremely low quality, and they break frequently in unexpected ways. I know, I've had it happen to me too. * You have a firewall active on your FreeBSD system. FreeBSD ships with three different firewalls. The simplest thing is to disable them for now. PF you can disable with the "pfctl -d" command. IPFW you can disable with "ipfw disable firewall". And last, ipf you can disable with "ipf -D". * Your IP settings are simply incorrect, but you don't recognize that. If you still haven't solved the problem by now, post some more details, like the output of the "ifconfig" and "netstat -rn" commands as well as the general layout of your LAN. Hope this helps!
