Hello,
Even if this is one of the most easy tasks to be done, I can’t seem to figure this one out.
My scenario:
Main router with external IPs and several internal networks. One of the internal networks has it’s own router after a 5GHz ptp link and I want to handle the NAT for that network in that router. I don’t have enough external addresses to route to the second router so that options is a no go.
My first thought was to just have a double NAT and redirect all the traffic from main router to the second router but after some reading I got the picture that double NAT can have some issues with VPN and other stuff.
So what do you all think? All answers are welcome!
Best regards,
Mattias
It really depends on what service you want to be available to clients behind that second router.
e.g. you could have basic NAT for the R2’s traffic on R1 and have NAT/PAT for the R2 clients on R2 if that allowed all required services to run.
Many permutations - more info required to filter out possible options.
Thank you for your answer!
Port forwarding, DHCP, VPN, simple internet usage and quite a lot of different services is the things we need today, maybe more in the future. My first thought was, as you say, to have a NAT @ R1 and NAT/PAT @ R2 but after some reading it made me unsure if it’s the best way to do it.
Please tell me if you need to know anything else to make it easier to find the best solution.
Best regards,
Mattias
Note that we want to manage it all from R2 as it is the end users private router while R1 is a company router that no one gets access to.
