I have a client who wants to set up a site-to-site VPN for a new office, Sonicwalls on both side. The issue is this -
The ISP for the new office only offers a private IP for the outside interface of the firewall. The private IP will be statically NATed to a public IP by the ISP.
Can I just point the main office Sonicwall VPN configuration to that public IP and trust that things will work?
I've not seen this setup before, and there are some logistics involved. I'd like to have a clue before I agree to give it a shot.
