Following basic config, the RB750 (running v6.34.6) can connect via a PPPoE connection on fibre and appears to correctly assume the connection’s fixed IP and pick up the DNS servers.
Via tools on the router, using WinBox, I can ping google.com and perform traceroutes, no problem.
On the client, via DHCP on the LAN port, a LAN IP (17.16.10.200) is assigned, with 255.255.255.0 subnet and router at 172.16.10.1 (DNS is same IP).
However, the client has no internet. From a terminal I can nslookup OK (e.g. google.com → IP#) but nothing else.
I feel like I’m missing something pretty basic, but can’t figure out what it is!
Any help much appreciated. I have attached a few screenshots.
Thank you for the prompt and super-helpful reply. You were correct! I’m up and running now.
So the NAT rules (and I guess, the filters) need to be applied to the (virtual) interface itself, being the last “link” (I could be guilty of mixing terminology here that has special meaning elsewhere)?
Glad to hear it works.
Yes, you need to adjust your fw rules to the corresponding interfaces.
For your follow up question:
There’s no need to rename interfaces - you can also name them “Harry” or “Garage”.
Correct with the vlan and the assignment of the PPPoE client to it.
And of course with the rules. But in case you just move your PPPoE client from ether1 to vlan10, there’s no need to adjust any rules because the referenced interface is still the same.
