I'm trying to host a few services under a few different domain names and 
need to be running multiple webservers to do it (apache 1.3x and 2.x).

If I have a single IP, will nat with FreeBSD 4.9 allow me to separate 
requests by domain name even if they share an IP?

Synopsis:

Apache 1.3 - bound to 192.168.5.1
Apache 2.x - bound to 192.168.5.2

natd entries:

redirect_port	tcp	192.168.5.1:80	www.foobar.com:80
redirect_port	tcp	192.168.5.2:80	www.otherfoo.com:80


I've noticed with older versions of FreeBSD that natd will simply 
resolve the names to the IP and as such it sees the natd entries as follows:

redirect_port	tcp	192.168.5.1:80	123.123.123.123:80
redirect_port	tcp	192.168.5.2:80	123.123.123.123:80

...it will then use the last entry for a given IP (the 192.168.5.2 entry 
in this case) which effectively breaks this setup.

Is there any way to work around this? Does IPFW2 allow for redirection 
by name?

Thanks!
