My other Linux server that is 2x2.5G bonded on Linux side and is connected to Layer3 TP-link switch. I didn't have to do any config changes on switch to make this bond work.

I bought this thing. It has 25G interfaces to be a typical bridge, but there is no way to transfer even 10G in bridge mode. Is this some kind of joke?

So nothing to be done on Linux itself ? Of course there is, bonds have to be configured on both sides of logical link.

Are ether1 and wlan2 members of same bridge? Broadcast packets are in principle not routed, only switched/bridged.

And possible misconception: if only traffic flowing is broadcast, then it'll only affect Tx counters not Rx (only port connecting to broadcast source(s) will show Rx activity).

mkx

Bridge is only necessary if one wants to switch between bridge member ports. If device is used as pure router (strictly routing between ports), then bridge is not needed (and if it's used then one has to take extra steps to block L2 communication between different ports).

Post textual export of configuration of your RB960PGS. I suspect that the problem is in routing indeed.

By disabling fasttrack, processing gets much more CPU-intensive. Depending on router model used it often means that router is no more capable of routing at high speeds.

Basic thing is DNS ... and if you want to use domain name globaly, then you need to register your domain and name servers for it globally (through one of domain registrars). Your cloud provider can probably help you with it. This process is not RouterOS specific in any way.

You can't block specific URLs (chosen between different URLs targeting same FQDN host or IP address). Generic reason is that there's no guarantee that whole URL will fit single IP packet.

The problem with communication pausing and/or packets being dropped when there's speed change (most notably from faster to slower, e.g. ingress port is 10Gbps and egress port is 2.5Gbps) is buffering.
