Ok, I am pretty inexperienced with IP addressing, particularly when it comes to
configuring firewalls with multiple public IPs, but at my small business I'm
the most experienced with IT stuff in general so I get to be the one who deals
with all this stuff. We have Comcast as our internet provider with a range of
public IPs of which we are currently only using one. I'd like to be able to
use another public IP in order to expose more services, such as a separate mail
or web server.Comcast provided public IPs: *.*.0.206/28Current WAN IP:
*.*.0.193/28Current WAN Gateway: *.*.0.206This was setup with a different
firewall (a crappy consumer box) before I got here, so after I started I
switched over to pfSense and just used the settings that were in the old box.
Currently, everything is working fine with this setup but now I am trying to
set things up so I can use another public IP (ie *.*.0.175) to expose different
web and mail services hosted on a different internal server and I can't get it
to work.What I have tried is to add a virtual IP (I've tried both Proxy ARP and
Other) with the following settings:Interface: WANIP Address: *.*.0.175/32And I
then setup 1:1 NAT mapping *.*.0.175/32 to 192.168.100.10.Lastly, I create a
firewall rule on the WAN interface to allow port 80 where the destination is
192.168.100.10.However, this does not seem to work...what am I missing?
