I see.
Only problem is I want (well, need) local PC's (on local LAN) to be able to access remote LAN with NAT address of server there.
I do have full access to that machine.
So, if I understand correctly, I should make route on remote server for local IP's with iroute, and push "route" commands, while setting NAT on remote server, where OpenVPN server is located?
Well, will try to fiddle with this later tonight.
Edit
Well, found temporary workaround in other post that makes it work:
Adding in /tmp/rules.debug line:
nat on tun0 from 192.168.0.0/24 to any -> (tun0)
.. and doing:
/sbin/pfctl -f /tmp/rules.debug
But, AFAIK, this won't work after reboots.. any way to automatize this?
