Would a plain unencrypted GRE tunnel between the TS and the file server alleviate the problem? Or if data security is a concern, set up a proper VPN between them. And use iptables (and other firewalls as necessary) to limit traffic as desired whether it's a simple tunnel or a VPN. (You don't want the tunnel to be an easy bypass around the firewall.)
