Public IP Subnets and multiple wan ip addresses

Hello!

I have a public ip subnet allocated by the internet provider on the main internet ip and also a secondary internet ip (that uses the same gateway as the main ip address)

I have 2 questions:
- how can I configure the public ip subnet in the policies (without nat) so all the internet requests will be forwarded directly to the servers behind the firewall disregarding the port used?
- how can I specify that certain types of traffic must exit to the internet only on the wan secondary ip? (the secondary ip is defined as an alias on the wan port)

Hi Liviu,

I am unable to understand your requirements.

- how can I configure the public ip subnet in the policies (without nat) so all the internet requests will be forwarded directly to the servers behind the firewall disregarding the port used?

Are you trying to map the internal requests directly on the Servers ? OR

Do you want to host your Server resources through the Public IP, in technical term "Virtual Host"?

Next, how can I specify that certain types of traffic must exit to the internet only on the wan secondary ip? (the secondary ip is defined as an alias on the wan port.

To achieve this you can simply create a Firewall Rule and create a MASQ to NAT traffic to WAN's secondary IP. PFA screenshot:
