Routing for clients assigned public IP via pppoe

[miastudio]

Thank you for your replies

do not use public IP for local-address=1.2.3.2

I also tried with a dummy 10.10.10.1 IP. But that did not make any difference. Ultimately, I followed this post: Give out Public IPs Using PPPoE Server

create one pool of useless IP, just used for pppoe local-address: 100.64.0.1-100.64.0.254

I'm not sure I understand what you're saying. Isn't that what i did with

/ip pool add name=pool-pppoe-public ranges=1.2.3.3-1.2.3.20

or is like you use twice (multiple time) the 1.2.3.2 for each connected users

I use 1.2.3.2 in 2 places:

/ip address add address=1.2.3.2/24 interface=ether1-isp network=1.2.3.0
/ppp profile add local-address=1.2.3.2 name=pppoe-public remote-address=pool-pppoe-public

But I do not use it for the clients / pool. That starts at 1.2.3.3:

/ip pool add name=pool-pppoe-public ranges=1.2.3.3-1.2.3.200

Nothing obvious, the default route is sufficient for all traffic which arrives at the Mikrotik. Are there any firewall rules which you have omitted to show?

No, that's it. I set up a bare system to test this

Whilst you need proxy-arp on ether1 for the WAN IP range, it would not be necessary on ether2 if the LAN IP range did not overlap with the private PPPoE pool.

I tried enabling it just on one interface and I was not able to ping out. That's why I enable it on both. It was also suggested in PPPoE with Public IP
