Configuring the router for my IPS in my pfSense 2.3

[_neok]

Hello! I need your help, my ISP does not provide the router configured, so they give me the data so I can configure my own.

They give me a public IP for my router and another IP that is theirs, both on the same subnet, which is / 30 prefix.

On the other hand they give me a range of public IPs (5 IPs) with their respective subnet mask (prefix / 29), gateway and DNS's.

Here comes my question, how should I make the interconnection between these two networks to be able to go to the internet from my LAN? Do I need to set up a Bridge between them?

I hope I made myself clear.

Thank you very much to all!
