can a cisco router do this and which ones

Are you saying you can static all 4 external IP addresses using 1 router and 1 wan ethernet interface and then create 4 networks each having its own external IP address. I take it by virtual interface you can configure that one wan interface to actually get multiple static IP addreses in this case it would be 4 ?

Sorry but gonna let Dove carry on this one as i am still learning myself

HI

can u explain what r u trying to configure and what shud b the end result ?

What im trying to do is see if 1 router and 1 ethernet wan interface on a cisco router and which one can actually use four static external IP addresses and then create 4 subnets and each subnet have their own External wan IP address. If what it will requrire is multiple virtial wan interfaces in its firmware please explain what models can do this.
