Hi, not very good at explaining, hopefully someone is able to help.
I have a range of IP addresses available from my ISP. Of which I used with a Mikrotic, it had PPPOE bridge, which allowed me to connect equipment on specific external IP addresses. My trusty old Mikrotik is really end of life, and my new fibre connection is just too fast for it.
Can I use Opnsense to do the PPPOE connection? And share / support the external wan addresses with the other devices? Whiles still using the Opnsense as my own firewall router for my local lan?
Hope that makes sense, but this is all a grey area for me.

Do you statically configure these addresses directly on the hosts that use them? Or do you want to (S)NAT them?

Yes, that is exactly what we have been doing. Each has its own IP wan address. (All from the same range)
Thanks for the reply.

Then I see no reason why this shouldn't work. It's just basic routing.

Could you elaborate? Or point to some info how it might be done? Very much a novice here, so any help welcome.

Can't provide step-by-step instructions, sorry. Set up PPPoE as usual, see the docs. Then you could e. g. configure the public subnet on a dedicated interface which the hosts using these addresses are connected to. And make sure not to NAT these addresses. You may have to manually configure outbound NAT.
There are other ways to do it, really depends on your specific needs.

Thank you for taking the time, will go have a play, see how far I get.
