Hi, I purchased routerOS v. 5.16 a few days ago for a client I wanted to setup. There’s whats happening:
They are using two links so I used PCC. But the problem is that one link is using an ADSL router, so the gateway becomes the modem. So the check gateway does not work.
I then tried Advanced Routing Failover without Scripting but the results not as expected; now I am off internet unless I disable one of the two links. If both are enabled, then I cannot browse.

Any help???
Put the módem in bridge mode and make mikrotik dial pppoe connection

I am guessing you have something in your config that is causing the issue. If the DSL router is doing NAT, you need to specify it as your default gateway and not the ISPs public default gateway for your DSL line.
Open new terminal and do a /export compact and post the results, it will be easier to address your issue with that information.
