Hi everybody,

I have a web server behind a firewall. I want to replace it with a new one,
without lost time in serving web pages. So I want to run two servers in parallel:
the old one, still fully functional, and the new one (on a different machine) under
construction, but somehow accessible to limited number of people who will work on it.

My firewall is running OpenBSD and packet filtering is is done with PF but
I can switch to IPtables if that's what it takes.

Please give me both conceptual advice (for example, is the best way to achieve this
by serving pages thru two different ports? Or is there more convenient way?)
and technical help (how to actually set up PF configuration or IP tables).

I am fairly experienced with Linux/Unix in general but my background is more
in scientific computation - not much experience with running web servers and
IPtables.

hello frank.

i suggest you using <apache rewrite code> , mean u can run many server in
LAN which only one port 80 open from outside access , all server can be run
at the same time with diffrent domain at diifrent server
