Is it possible to use NAT (or some combination of NAT and other trickery)
to redirect an address on your WAN interface to another external IP address
(not on the WAN interface, but at some other site).
e.g. Site A has Public IP address 184.108.40.206
Site B has Public IP 220.127.116.11
I would like to redirect any requests that come in to 18.104.22.168 on port 80 to
go to 22.214.171.124 (also on port 80).
The goal is to be able to redirect HTTPS requests to a block of IP
addresses to a single IP address (but on different ports) to avoid needing
a different public IP address for each SSL encrypted site.
I already know about wildcard certs and certs with multiple host names on
them and also SNI, all of these are problematic for one reason or another.
If there were someway to redirect requests as mentioned above, I could
colocate a monowall box somewhere where I can get the IPs I need and
redirect them to the primary webserver, which unfortunately has a pretty
limited number IPs available.
