I have a system that we NAT through a firewall. A partner whom we are setting up a VPN connection with only will accept registered IP addresses. The way our network is setup, I will have to NAT this address again to a public IP. So I am wondering what are the pro's/con's of doing this. If it is not a good idea, then I will engineer another way to set this up. Thanks!
There will not be any issue in converting the private addresses into a public IP address. the below document explains with an example in which the network manager has two ranges of IP addresses that are registered on the Internet. The network manager must convert all of the internal addresses, which are in the 10.0.0.0/8 range, into registered addresses. The ranges of IP addresses that the network manager must use are 172.16.1.1 through 172.16.1.62 and 172.20.1.1 through 172.20.1.254 .
