Hi, I'm pretty sure I'm over-thinking this, so I thought I'd step back and see if I can get some hints as how this sort of a set-up is done "properly" by pros.
Say, existing set up: [internet] -- [pf] -- [ public-ip-net/24 ] Want to add/connect a private 192.168.0/24 to existing [ public-ip-net/24]: ... [ public-ip-net/24] -?- [ obsd box ] -- [ 192.168.0/24 ] Goals: 1. Hosts in both networks "talk" with one another freely. e.g., hosts in existing network see hosts in to-be-added 192 network, as they are; i.e., not NAT-ed. And vice versa. 2. Hosts in 192.168.0/24 have access to the internet through the same/existing gateway. I lack some knowledge wrt to the subject, where I think, I am filling the "holes" with, possibly, far too complicated ideas. Appreciate any and all help offered. Thanks, --patrick
