Re: Transparent network.

Fredrik,

I'm new to OpenBSD too. I just built my Firewall/NAT yesterday. I'd 
worked on it before, but had some problems. I fixed it when I combined 
both the NAT section of the Networking part of the FAQ, and the similar 
section from the FreeBSD (freebsd.org) faq.

With mine, only my Mac and OpenBSD box have public numbers. My printer 
and my Windoze machines have public numbers, and everything seems to work 
out well. Just don't forget to edit the hosts files on all of the 
computers correctly.
