Static IP on a Bridge
Hey everyone. I've successfully setup a network bridge in /etc/rc.conf. However, I am only able to access the network if I dhcp on bridge0 *after* the bridge is configured. If I try to set a static IP on the bridge, things don't work. Here's my /etc/rc.conf: cloned_interfaces=bridge0 tap0 tap1 ifconfig_bridge0=addm re0 addm tap0 addm tap1 up inet 192.168.1.6 netmask 255.255.255.0 ifconfig_re0=up ifconfig_tap0=up ifconfig_tap1=up defaultrouter=192.168.1.1 bridge0 is configured with the IP 192.168.1.6, but I can't ping out. However, once I run dhclient in bridge0, things magically work. Does anyone know why the above won't work? Thanks!
