Everything was working fine during months. I had a new box from my internet provider and now. Monflo is not working. Firewall nat dmz upnp all is the same as the old one. But I can't connect correctly from any other device pc/mobil wifi android when they are not in my home network. Please help.

A friend of mine had the same problem, but I work in a hospital and it had spread across the network, so no one could connect and the images were freezing. So when I was seeing a patient, the esophagus images, the previous patient on my computer would freeze and I had to wait maybe 10 minutes for the images to be fixed. This problem, as far as I know, was solved as follows: the hospital installed a new firewall and changed the Internet provider. I hope this information will help you.

Switching to a new router can disrupt Monflo's remote access. Here's how to fix it:

Check your router settings: Ensure firewall rules allow Monflo traffic, NAT settings permit external connections, and UPnP is enabled for automatic port opening.

Verify Monflo configuration: Double-check port forwarding for Monflo's internal IP and ensure it uses the correct DNS servers (try Google's public ones).

If the issue persists, contact your internet provider or consider resetting your router (last resort, back up settings first).

Hi Shakachezwam,

It sounds like the new router may be blocking some of the ports that Monflo uses, even if firewall, NAT, DMZ, and UPnP settings look correct. I’d suggest:

Check port forwarding: Make sure Monflo’s required ports are correctly forwarded on the new router.

Test with a direct connection: Try connecting one device via Ethernet to see if Wi-Fi might be causing issues.

Double-check external access: Some ISPs block certain ports by default; contacting them to ensure nothing is filtered could help.

Update Monflo & firmware: Ensure both Monflo and your router firmware are up-to-date.

Often, switching to the new ISP box requires re-verifying port forwarding and UPnP rules. Hope this helps get your remote access back!

If it worked before, the new router is likely the problem. Check if you’re behind CGNAT, and make sure port forwarding is correctly set, as some ISP routers block external access by default. You may need to contact your ISP to confirm.

It sounds like the new router might be causing the issue with port forwarding. Double-checking with your ISP about CGNAT and port settings is a good idea. Sometimes, those default settings can be tricky to navigate, but getting clarity from your ISP should help resolve the problem.
