I guess you're not being clear enough.
You are connected to the same router as the PPPoE clients?
Why are you trying to masquerade your traffic when it can simply just be routed?
Do the PPPoE clients have any firewall? Are the IP addresses of PPPoE clients properly visible in the status of PPPoE connections?
If I'm being wrong anywhere, please attach a schematic of the network connections.
Hi.
Yes, I am connected to the same router as the PPPoE clients, it's a CRS125-24G.
I wasn't trying to masquerade the traffic, not at first. But for some reason, if I don't add that rule on NAT, my PC won't get routed to any other network. My PC is connected to a port that is part of a switch configuration, porta 7-24 are switched, isolated, and I added cpu port also, so the switch traffic can be processed by RouterOS. PPPoE clientes are on port 20, and my PC on port 24. My PC have no direct access to port 20 as the switch are configured with ports isolated, so it must be routed by RouterOS.
The PPPoE clientes have no firewall, I can ping them from inside winbox or terminal, they respond normaly. But my PC can't ping them, even tho it can ping other devices connected to the same ports in the switch.
The PPPoE clientes have their IP visible on routeros (PPP -> Active Connections).
I drew a simples schematic on Paint. On the schematic, my PC gets routed to the "Test notebook" that is on another network, and to the "Other device", that is also on a different network.
