Assuming Comcast gave you a contiguous netblock, your netblock would be
*.*.0.192-207 (192 being the network address and 207 being the
broadcast) leaving 193-206 as usable IP addresses. *.*.0.175 isn't in
that net block and so its not likely that its available for you to use.

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: *.*.0.206/28
Current WAN IP: *.*.0.193/28
Current WAN Gateway: *.*.0.206
This 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: WAN
IP Address: *.*.0.175/32
And 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?
