Hi,
on openpli image is there a way to block ALL Internet traffic when VPN connection goes down?

Thanks in advance

Hi,

 

If you drop ALL internet traffic this means that you will NEVER be able again to connect to your VPN, since ALL traffic will be blocked!

So the VPN port must remain open, and you only need to open this one on your ISP router/firewall to your STB, and use a strong authentication mecanism.

Can you try to post a configuration for Openpli with OpenVPN (default configuration and port 1194 I suppose)?

You could set a hardcoded set of routes, that routes everything to the VPN next hop, except the public IP of the VPN endpoint? And maybe to local LAN so the default gateway can still be found?

Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.

I understand but I'm not able to do that (I'm a newbie in Linux world)...Could you post a working configuration or simply indicate which commands should be used?

 

Thanks

I'll try, thanks...Maybe it shouldn't be the right way...With ip tables support it should be easier or not?

 

Please, if somebody has new ideas, post something for the community ;)

 

Thanks

iptables could be an option to, but afaik it isn't (fully) implemented in the image. An STB isn't supposed to be connected to the outside world...

This is the OpenPLi forum, not the XTA forum.

Here you see a very nice example why we don't like people to edit their posts.
The edit time is rather limited already, but apparently still too long.
So for anyone who is wondering "why can't I edit my post", well, this is why.
