DNS poisoning?

[airvpnclient 13]

Starting this morning, my RPI servers started experiencing disconnects.

 

I have to run tcp client, since UDP on 443 seems to get messed with somehow.  Is there a fix?

 

Everything has been working with TCP

 

But suddenly,  began disconnecting and reconnecting almost immediately again and again.

 

Thankfully, I am sorted now.

 

Based on info in the forums about possible DNS hijacking, I changed my openvpn config to Canada from all North America and for greater certainty reset my iptables rules from the latest client.

 

Best way to do this, I found is by running the latest client on my linux laptop, exporting the rules using (as root)

 

>iptables-save > iptables_2016-03-12.saved

 

That generates a file that can be loaded on any linux box using:

 

>iptables-restore <iptables_2016-03-12.saved

 

then remembering to do:

 

> sudo netfilter-persistent save

 

This guarantees the network lock persists across reboots.

 

My connections have been up 40 minutes and an hour plus since then.

 

Anybody else notice anything?

You posted this in "Troubleshooting and Problems" but it doesn't seem like there is anything to troubleshoot,

nor it seems like there is a problem, according to your statement:
