Bridging 1 lan port on 1570 to the WAN port

[scotdesort]

Is it possible to take one of my available LAN ports and bridge it directly to the WAN port, leaving the other LAN ports configured as-is?

The goal is to have a LAN port that is not NAT'ed or even filtered/secured in any way, directly to the outside. The port would then in essence have the same public IP address as the WAN port does. All traffic passes in and out with no filtering necessary.

We will be connecting a separate managed Meraki security appliance to this port, which will handle all security and PCI compliance from our POS software vendor. They want the Meraki to be connected directly to the "ISP modem", but we only have single WAN connection from Verizon FIOS. So it has to be fed off of the Checkpoint appliance somehow.

Thanks

You can bridge the WAN port directly to a LAN port - but the other LAN ports then have no more internet and need an own ISP connection (eg over DMZ).

Ehhh, no good. I’m going to go for double NAT and hope for the best. Thanks!
