Hi! I recently changed internet provider, and had to factory reset my MikroTik. Made just basic configuration for small office and vpn.
One thing that stopped working after that - Team Viewer. Everything work well, except this one. It says - “Not ready. Please check your connection”
At first, I thought about DNS (manual 8.8.8.8 and 8.8.4.4), then added ports to firewall, then I tried UPnP and nothing helped.
And one more. I have static IP address, and router receives it automatically (maybe something there?)
Can somebody point me what can it cause? I have the same provider in next building where TP Link installed - everything works well.
If any additional informational needed - just let me know. Thanks!
All done except 2 - it does not allow me to use ‘network’ parameter. There is no such thing
I’m not strong at firewall rules. I was recommended to use what I had to stop all external connections.
I did not update to v7 firmware as this version shown as unstable
Still - no team viewer. I don’t know why

Since you have no firewall rules and all is allowed, yikes, would never connect this to the internet…
No nothing should block it. ( did you try disabling upnp ).
Suspect something on the PC, firewall, new OS, something ???
Yeah, we’re using it now. But some users still asking for TeamViever…
I was trying on different computers, and the same result every time. I even connected PC without router and everything working fine. One thing I noticed.
It all happened after internet provider was changed. Router was factory reset, and new configuration was created. I remember that old configuration had different NAT rule. This one has:
add action=masquerade chain=srcnat out-interface-list=WAN and old one had something with external IP. I’ll try to upload old configuration and export settings when I’ll be there
—update. found some info. I was talking about using action scr-nat + external IP instead of masquerade. I don’t know if it can help)
