Hi, I have a such a network:
ISP modem <-------> (WAN public IP ) router Netgear (LAN) <-------------> router Mikrotik RB760IGS <------------> switch Cisco <--------> end devices
When I log on the Mikrotik router I can ping DNS 8.8.8.8 or 1.1.1.1 without any issues. I can’t however ping DNS or open a website from any of end devices. Also, when I connect to Netgear router I can ping DNS or open websites too. Mikrotik’s website is locally accessible. It seems that something is misconfigured on the Mikrotik router. I’ve checked Mikrotik firewall, relevant ports are open such as 53 UDP or 80 TCP. It looks like some option either hasn’t been checked or a service hasn’t been turned on, probably a small issue unless the device is damaged.
I’d appreciete any help with explaining what might be a cause for this problem.
Regards
