PPPoE is documented in the handbook, I'd suggest you set that up first
together with a simple pf firewall to secure the system. There are
plenty of howtos for PF+NAT+DHCP. 

I would suggest you also run a DNS cache so dhcp clients can be given a
fixed private IP address instead of the ISP servers. 

FWIW you may not actually need two NICs, if you have a modem/router
with multiple ports you may be able to get away with PPPoE and your lan
sharing the same NIC (your wan interface being tun0).
