Hi,

Using RouterOs with both Hotspot and am adding PPPoE service. Have PPPoE configured and working,
just that certain websites are not working.

If I switch the same PC to hotspot works fine. The websites on port 80 do not show up, but able to access SMTP on the same server on port. Traceroute will get me to the host.

I checked the PPPoE server settings and do not find and web proxy or other setting that would effect web traffic in any way. Firewall rules are fine because most site are accessible.

Using version 2.9.50 of router OS on RB525 board.

Anyone have any ideas?

Are you running PPPoE and Hotspot on the same interface? According to Mikrotik staff, that's not a supported configuration and will not work. Also, 2.9.50 is really, really old.
