Without knowing what you refer to as 'The Old Way' Vs 'The New Way', or how 
your 'main rig', Vs your 'old rig' may have been configured, I'll try to make 
a guess, or two:

1. Old Way = netifrc

You configure /etc/conf.d/net using the well commented example provided in:

/usr/share/doc/netifrc-*/net.example.bz2

You symlink your interface enp3s0 to the net.lo netifrc init script and add it 
to the default runlevel:

ln -s /etc/init.d/net.lo /etc/init.d/net.enp3s0
rc-update add net.enp3s0 default

then (re)start, check the status, or stop your newly configured interface, 
e.g.:

rc-service -v net.enp3s0 status
rc-service -v net.enp3s0 restart

More detailed info than you should ever need and all on one page, is provided 
here:

https://wiki.gentoo.org/wiki/Netifrc


2. New Way = DHCP (?)

Although dhcp can be configured as a fallback option within /etc/conf.d/net in 
addition to static addresses, gateways, etc., it can also be set up as a 
standalone service without netifrc.  Emerge dhcpcd and add it to the default 
runlevel.

If you have set static IP address(es) at your home router for the old box and 
its MAC address, then that's all you need to do before you run:

rc-service -v dhcpcd restart

If you prefer to not set up a configuration for your old rig on the router, 
then you can add a static IP address in your /etc/dhcpcd.conf.

Again, more  info than you should need is provided here:

https://wiki.gentoo.org/wiki/Dhcpcd

HTH, otherwise ask if you get stuck.
