Hi - Just completed installing a brand new RB2011 (non-wireless) router. I went with the default config and everything seems to be working except for this one issue. I have a hardware switch connected to the ether3 port (which is switched to master ether2 internally, as per default). I have computers connected to the hardware switch that cannot see each other. I am not able to ping any of them from any other one. However, I am able to ping another computer that is directly connected to ether5 port on the router. I suspect something in the router is blocking the traffic from one computer to another on the hardware switch. The reason I say this is all of this used to work fine before I switched the router to RB2011. Can any of you gurus help with guiding me on what needs to be corrected in the default config?
Appreciate your reply. Nothing has changed on the computers from before, when I was able to see the computers connected to the switch. The only change in the scenario is this new router that is connected to a hardware switch. I actually turned off the windows and the third party firewall on both computers and still have the same issue. This is why I suspect the firewall rules that came set up preconfigured with the Routeros or something else in the router. Don’t know what and I am afraid to touch anything.
When you connected the computers to the new Router, they will see that they have a new connection and set the connection to Public. This will re-enable the firewall.
Traffic from a computer to another computer connected to the same switch will not reach the router for it to have an influence.
Just wanted to post back to let you know that your suggestion helped. I changed the network to Private and I was able to connect to my other computers on LAN,
