My ISP provides me a single public IP to my PPPoE link and today I do the usual that is to Nat that address to my internal network and just provide the traditional routing functions.
Now I want to use a new router/security device that doesn't support PPPoE for their WAN link so I need to find a workaround.
I see couple of options.
- A 1:1 Mapping between the public IP and a Private IP
I think I can achieve that, but I am interested in a more transparent solution.
- A way to put the public IP address on my new router/security (non mikrotik) device. (Desired)
So the Mikrotik device does the PPPoE authentication but the IP address gets assigned to my NonMikrotik device. I do have fixed IP, so I only need to solve the PPPoE part on the Mikrotik and doing some translation (At L3?) between the PPPoE session and my device.
Some hints will be appreciated. I have some networking background so just a general direction will be great.
