Public IP to Local Client

Good day,

I have the following setup

WAN- 88.X.X.194/30
LAN- 10.10.10.1/24

I have several High Sites in the 10.10.10.0/24 field and on one specific one(WAN- 10.10.10.17 Lan - 172.18.0.254/24) there is a client (172.18.0.77) who needs a Public IP.

2 questions. Firstly, would I be able to forward the Public IP to the client and still be able to share internet access to the rest of the 10.10.10.0/24 High Sites and secondly, could you please advise on how to do this. I normally work with wireless and have no knowledge on advanced routing :S

Thanks in advance.

Your WAN address is a /30, which is only one address for your upstream gateway and one address for your router. You have no other free addresses to allocate to a “client”. You could dst-nat all inbound connections to that IP out to the “client” so that they could run a server, but all of your other masqueraded clients/devices will still appear to come from that same IP when they are accessing the internet.

Hi and thanks for the reply.

Is it possible if you could help me on some configs for this? Routing is not my strong suite and I don’t have another connection to test on and the risk of downing my entire client base is not one I am willing to take :slight_smile:
