First hello everyone!
I have been using mikrotik for a while now, the Rb952ui-5ac2nd-tc Hap Ac Lite 2.4 / 5ghz Towercase. With RouterOS 6.40.8. My public ip is almost static since every so often it changes, but the ip is assigned directly to the router by my cable company. The problem is when there is no internet, I stop having internal connectivity from one pc to another on my local network. My Plex movie server does not work from any television or even the play station.
In my DNS server I have as static 192.168.88.1 and Then in DNS servers the typical 1.1.1.1, 8.8.8.8 / 4.4.
I am missing something in the configuration?
Thanks in advance.
Hello @hfsotous
if I understand you correctly your connections should look something like this:
PC ----> Mikrotik ----> ISP Modem ----> Internet
First some cable company’s offer to set the Modem/Router(ISP Specific) to Bridge mode. Like this it should not get Double NATed.
The other Part is maybe that the wrong Gateway is assigned?! Instead of the Mikrotik Router were your devices (LAN) are connected they point to the Gateway of the ISP Modem/Router.
If both are not the case maybe a Routing Table issue or if you try to reach the devices over the DNS address the local DNS Server is not the first source.

Nowadays many applications don’t work without Internet connection.
Having a local DNS server is good for caching, but it can’t solve the problem since it too needs Internet connection to its uplink servers (ie. 8.8.8.8 etc. are in Internet).
