Working with pseudo-ethernet on WAN

I'd like to conduct an experiment in working with virtual interfaces and tweaking the NAT rules so that I can  separate my home internet traffic from my web server for better security logs.

When adding a peth0 interface to my eth0-wan connection, will this pseudo do DHCP?

If that does indeed work and then tweaking NAT, it would look like this right?

eth0 - 1.1.1.1
peth0 - 2.2.2.2

Lan1 - 10.0.0.1 - NAT 1.1.1.1

Lan2 - 10.20.20.1 - NAT 2.2.2.2
