Watchguard x750e Configuration Issues

Hi,

We've inhireted a network which uses the IP range 137.121.82.0 /24, we're trying to configure a new x750e using this range as the Trusted network. On the External, we have a /29 subnet of IPs to use.

The current configuration is as follows :

Eth 1 Trusted Interface : 137.121.82.230 /24
Eth 0 External Interface : This is using the PPPOE client and obtaining details via DHCP.

The problem is that traffic is not being routed externally. When configured as follows :

Eth 1 Trusted Interface : 192.168.2.1 /24
Eth 0 External Interface as above, PPPOE with IP via DHCP, traffic is being routed fine.

What could be the issue here?

By default the dynamic NAT is only allowed from the private IP ranges, viz.:
10.0.0.0/8; 172.16.0.0/12; 192.168.0.0/16

As you have 137.121.82.0 /24 on trusted; you need to go to Policy Manager; Network->NAT; and add 137.121.82.0 /24 to be allowed as:
In Policy Manager; go to Network->NAT; click Dynamic NAT tab; click Add; add entry as:
From: 137.121.82.0 /24; to Any-External

Move up if you wish [doesn't matter]; save settings to firebox. I would like to point out to you a potential problem with this configuration, if on internet there exists some server(s) which is/are running on same IP subnet 137.121.82.0 /24; then you would not be able to access that server when behind firebox.

Please implement and update.

Thank you.
