Setup using DST NAT on fw to local IP's
Wanted to setup up a network using ISPconfig 3 multiservers on a local 10.0.0.x network and my fw would have a Destination NAT so all Internet IP's in a class C would have a 1:1 correlation for the last octet:
18.104.22.168 -> 10.0.0.12
22.214.171.124 -> 10.0.0.45
Anyone doing this? Not sure if Linux DNS servers can handle internal and external IP's. I have a Windows DNS server (SimpleDNS) that can. The ultimate goal is to setup a clustered remote system and in the event of a failed host have a script change the IP on the DNS and the actual server would be 100% the same. Also, if I had to renumber my network because of a move, etc I would not have to change the IP of each VM, just make a script to change the fw rules.
Any pitfalls trying to do this?
