Route add’l IP assigned by ISP to internal web server

Locked

I need to configure my network such that an additional public IP assigned by my isp can route to my internally hosted web server.

Network equipment involved in this discussion:

Cable modem with 2 IPs on the account.
One is assigned to the modem one is for use elsewhere (web server).
-connected to —->
Sonicwall firewall
-connected to—->
Layer 3 switch stack ( Netgear FSM series )
-connected to—->
Internally Hosted Web server

I’ve got the public IP from the isp assigned to the NIC of the web server and to the web site in IIS.

I need to know if I need to configure a vlan on the switch stack in order for the traffic to traverse the network from the firewall to the web server, or if there is something else I should be doing.

Thanks,
Justin

Not sure you can do that with your router/firewall

You need to be able to do port address translation (PAT) since the NAT rules overlap.

What you’re attempting is ‘Many to One NAT’

If your device can do it, this link may help:
