I've recently purchased a rb433 and configured it to masquerade to ether2 (WAN). I have a PC on ether1 (192.168.1.0/24). Everything is basically working, but my dl speed dropped from 20 mbit to ~1 mbit. When I connect my PC directly to the modem it's back to normal.
My firewall settings are very simple:
RouterOS version 4.14.
Code: Select all
0 chain=input action=accept connection-state=established in-interface=ether2 1 chain=input action=accept connection-state=related in-interface=ether2 2 chain=input action=drop in-interface=ether2
Where the problem lies? How can I debug it?
I checked link quality with pingtest.com and got grade A, no packet loss.
