DHCP server isn't serving as a gateway

If you provision an Airwall Gateway, but don't set the DHCP gateway or IP, the DHCP server won't serve as a Default gateway.

Not specifying a gateway in the DHCP server configuration causes the Airwall DHCP server not to include the DHCP Router option, so the DHCP client does not configure a default gateway.

Solution

Configure the gateway or IP in the DHCP server configuration.:

Note: Not specifying a gateway is a possible, but unusual configuration, and should only be used when you want to configure a single isolated subnet. For example, a subnet for networked PDUs that should not have any outside connectivity aside from remote access through an Airwall Gateway used in conjunction with SNAT over the Overlay port group.
