Re: [LUG] FW: What would you use for this?

["Neil Stone" <Neil@xxxxxxxxxxxxxxx>]

I think you're looking at "Source based routing" it has been ages since I did it, 
but with iptables you can tag packets based upon their source, dest, type etc..etc.. 
Then these tagged packets can be sent out via one route or another based upon your 
rules...

make sence ?
