I have to change a TP-Link router that is configured with a PPPoE user.
I was told that putting the MikroTik on PPPoE with the same user and password, the router on the same network (192.168.8.0/24, with .1 as gateway) and no DHCP (all the PCs have static IP on Windows) it will work.
But it doesn't.
When I change the TP-Link for the MikroTik, not even one PC gets connection to internet (I just unplug the WAN cable from the TP-Link and plug it on the MikroTik, port 1, and another ethernet cable that goes to a switch, port 2).
BUT, if I connect a PC into another port or using WiFi, that PC (with static IP on the 192.168.8.0/24 network) gets internet.
Edit to explain better the situation. Read from here.
There is a network using static IP on all of its devices. I need to change the router of that network for a MikroTik.
I configure PPPoE on the router MikroTik 941-2nD.Then I put the router on the 192.168.8.0/24 subnet, with 192.168.8.1 as gateway.
Deactivated DHCP, leave NAT checked (using Quick Set). Wireless disabled.
After that, I used some rules to block sites:
/ip firewall layer7-protocol
add name=facebook regexp="^.+(facebook).*\$" comment=FBK
/ip firewall mangle
add action=mark-connection chain=prerouting protocol=udp dst-port=53 connection-mark=no-mark layer7-protocol=facebook new-connection-mark=facebook_conn passthrough=yes comment=FBK
add action=mark-packet chain=prerouting connection-mark=facebook_conn new-packet-mark=facebook_packet comment=FBK
/ip firewall filter
add action=drop chain=forward packet-mark=facebook_packet comment=FBK
add action=drop chain=input packet-mark=facebook_packet comment=FBK
The same with Messenger, Twitter and Instagram (You just change the site name on the command for the one that you want to block. All the "facebook" for "twitter" to block twitter).
After that, I made the change of routers.
I plug in the Internet cable on the Eth1 port. I plug in an Eth cable that goes to a switch on the Port 2.
Aaaand, the network doesn't have connection to Internet. Funny thing is, if I connect another PC on other port (3 or 4 of the MikroTik). That PC gets connection (previously configured with an static IP on the 192.168.8.0/24 subnet).
