Hi Everyone, this should be an easy question - perhaps I'm a bit slow today! I have a client with a LAN behind a NAT firewall, so thay have 1 Public IP address. They are using CA's Arcserve Backup for laptops and desktops which connects to a service on one of their internal servers. It connectes via Ip, a specific port, using the server name. This is no problem and I have an entry in the workstations hosts file so it can find the server. The problem is that all these machines are notebooks, and are often outside of the LAN, on the internet. When on the internet they cannot (of course) find the server as it is on a private IP address, behind the firewall. Is there an entry I can use in the workstations hosts file that will try one IP first, then another if that is not successful? Or a better way?
