 |
|
I'm using a Sun QFE card, with the four ports bridged into one interface, configured as following in /etc/conf.d/net:
| Code: | config_lan0=( "null" )
config_lan1=( "null" )
config_lan2=( "null" )
config_lan3=( "null" )
bridge_lan=( "lan0" "lan1" "lan2" "lan3" )
config_lan=( "192.168.17.1/24" ) |
It works quite well for the most part but for two oddities:
- I had to add a routing rule routing from lan, back to lan, to let traffic pass between the bridged ports. How come -- isn't a bridge supposed to...bridge?
- Every once in a while, almost always at midnight sharp, the bridge device stops responding, refusing to communicate to any devices on it. Nothing special shows up in the system logs, and nothing but a reboot fixes it. Why does it do this and how can I stop it?
