thank you jimp, I googled the wrong ifconfig manpage ;-)
a question on creating the bridge from a newbie like me:
I currently have a vlan interface, lets call it vlanForMonitoring. There's always only one client connected to it, this client shall be used for analyzing traffic from and to the wan interface.
Can I do something like the following?
How about Firewall rules? Is the bridge enough to pass traffic from WAN to vlanForMonitoring or do I still have to create firewall rules? How would they have to look like? Thanks for any hint :-)
