Symptom: I Want to Assign a Unique Public IP Address to the Resource on the OPT
Interface
Verify that the OPT interface is in NAT mode, then navigate to the
Network > One to One NAT
page,
check the box next to
Enable One to One NAT
, and create an entry that associates the public WAN IP
address with the private (remapped) internal IP address of the resource on the WAN. For example, in
the public IP address 204.180.153.201 is associated with the internal IP of 192.168.200.100.

on this page to save and activate the change. Create a firewall policy to allow access to the
server. Enabling NAT only associates the IP addresses; it does not enable connectivity.
Symptom: Internal Users Are Having Problems Accessing the Server on the OPT Port
Create a loopback rule to allow internal users on the LAN interface to access the server on the OPT
interface using its WAN IP address. The easiest way to do this is to use the Public Server Wizard.
Symptom: Users Across a Site-to-Site VPN Tunnel Unable to Access a Server on the
OPT Interface
Select the radio button on the VPN policy’s
Advanced
tab to allow the tunnel to terminate at the
LAN/OPT interface; by default, it only attaches to the LAN interface. Enter the OPT interface subnet into
the remote side’s VPN
Destination Networks
policy.
Global VPN Client Troubleshooting
Symptom: GlobalVPN Clients Are Unable to Access the Server on the OPT Interface
Select the radio button on the GroupVPN policy’s
Advanced
tab to allow the tunnel to terminate at the
LAN/OPT interface; by default, it only attaches to the LAN interface. Verify that the GroupVPN policy is
enabled.
