Diffrent Public IP range for WAN and LAN

[sangram palande]

I have to configure a firewall on a network where we have received diffrent Public IP range for the WAN and LAN.

I need to make sure that all internal servers are accessable from internet with public LAN ip address. The firewall has default route configured going to the ISP WAN router.

Do I need to configure anything diffrent for the servers to be accessed from the internet(apart from Access rules and NAT) with public LAN ip or will it work normally?

If yes, please specify the config.

Hi Sangram,

Only Access Rules, NAT rules, and routes would be required. Take a look at these videos for some config examples:

Hope that helps.
