I have actually set a bridge up before but i rebooted the box from some reason, i'll try that again. These are the options for me i think:
1. Bridge the connections and some how get some traffic shaping on that for certain traffic. I'm going to set the bridge back up and test it again.
2. Or set the ip and subnet on the other side of my lan to a different one that i have for say the other interface and route between them two and use some sort of traffic shaping on that.
I'm still playing about with this all, i really need to limit incoming traffic and outgoing because of high bandwidth usage. I'm going to google and play about with this
Anyhow its all a good learning curve, thanks.
