Hi Sorry relpying without looking at diagram (can't access).
This should not be a problem, connect the 4 adsls to 4 ethernet ports (bridged mode and run pppoe), then use iproute and iptables iptables -t mangle to mark the packets eg mark 1 for smtp mark 2 for ftp etc Then use iproute to do the routing based on the marking and then bos your uncle. This would work similiarly if you had a mini switch and the 4 adsl modems and you did not use pppoe. again mark and use iproute to route via the adsl modems Alex On Mon, Jul 26, 2004 at 03:41:08PM +1000, Terry Denovan wrote: > > > > > > > Hi SLUG, > I am wanting to know if its possible to setup a Linux Box that will allow me to > connect 4 ADSL Connections to my Internal Network, and use only 1 internal > gateway.
