Hello
Opening a global topic about firewall options that I don’t completely understand even looking in forums and manuals:
Context : using RUT 95[01] vai 4G. On local network behind the RUT, there are Windows or linux PC accessible via Teamviewer, VNC, etc …, Lan Cameras
to access them, I’m using port forwarding rules set in the RUT95X (explicite for VNC like 5900 to 5900, or redirecting like 9876 to 443 of the camera).
But in our experience, removing Software flow offloading resolved our VNC access issues, and improved (a bit) access to the cameras.
Obviously test were made in the best 4G conditions to avoid this variable.
- software flow offloading :
- we don’t understand clearly the relation between VNC and this option ?
- can someone expain us (we want to know just to be in confortable conditions with what we set!)
- Automatic helper assignment :
- if I understand well help to automatically create rules depending on trafic? From what I read on internet, some linux kernels stop using this since a while : Automatic Helper Assignment | firewalld
- So is this option still relevant?
- Note : yes I red the topics related to people deactivating this option due to passive FTP issues
- note 2 : we didn’t notice big changes with the option kept or disabled …
thanks and BR
