Site-to_site VPN with NAT's hosts - 9.Sep.2004 8:13:00 AM

One of our business partners needs us to configure an IPSec site-to-site VPN with them where they can FTP files to an FTP Server at our site with special file encryption.

The strange thing about it is that our FTP server must respond to an IP address that they assign us. In essence thew want us to NAT an internal addressed FTP Server to (their public address) However our public address to the internet for this FTP Server is

This seems rather odd to us, but they say all their other partners do it. They have said only CheckPoint NG will support this.

Any help would be appreciated.

Hi W,

If you have a site to site VPN, then *they* can publish the site to the IP address they require. This is what I do with ISA firewalls on each site. I publish the server on the remote network to the local network, or vice versa, and than it exposes the required address.

BTW -- ask their security experts what security they get by limiting access by IP address! That's nuts! They should require authentication, IP addresses are rediculously easy to spoof.
