We have a Watchguard Firebox II that was setup and configured by our previous IT person. He did not document the network properly and we are playing catchup. Of course, we need to login to the firewall to change some settings and we can not login using the System Manager. Some details on the config:
Firewall internal IP: 10.0.0.1
System Manager version: 7.00-B2448
Firewall Model: Firebox II
The trusted network cable is connected to the network switch. The port shows the link light is ok, and when trying to access the firewall through the System Manager, network activity is happening on both the Firebox trusted network port and the network switch port.
The problem is this: System Manager asks for an IP and Passpharase. I enter 10.0.0.1 for the IP, and the passphrase, but it immediately kicks me out saying: 'A connection could not be established. Check the IP address and your passphrase and try again'.
Now it seems that the utility is not finding the firewall as the error message comes back immediately. Any insight into this issue will be greatly appreciated. We can not reset the firewall back to factory settings because it is configured with a bunch of port forwarding information that has not been documented.
