I was on some Kong build for 2 years (I guess). 4 days ago Cyberghost made a huge change in their vpn servers and I couldn't make it work with that old build. Can someone point me to a recent good build with OpenVPN working fine on R7800 ? Thanks | |

In my previous build, when something was wrong with vpn client configuration, we could see the status in this page. Now it disappears after trying to connect  I managed to connect to the VPN server (CyberGhost), I got a "Client : CONNECTED SUCCES", a "Local Address : X.X.X.X", no "Remote Address" (but I guess it's ok, as far as I remember it worked without one) But I can't browse anything and "TUN/TAP write bytes" is stuck at 0.

That instructions are not up to date, as I said they messed everything 4 days ago. The ovpn file in my previous post is the new one I got from them, and it works fine with openVPN GUI on my computer. | |

I found last night what was blocking writing through the tunnel : "Compression : No". I switched it to Disabled and it worked. Today I followed your instructions and removed everything from additional config. Seems smoother, thanks. Added some tuning I had with previous build for better download speeds, seems to works as before : | Code: | | fast-io # (Experimental) Optimize TUN/TAP/UDP I/O writes by avoiding a call to poll/epoll/select #prior to the write operation. nice -20 # Set highest possible nice priority auth-nocache # Don't cache username/passwords in virtual memory |
In previous build I had that : | Code: | | status /tmp/vpn-status status-version 2 |
Maybe for a watchdog but I can't figure how or if I was using it. I have a script on my NAS that pings google dns each minute, and if doesn't get a response it ssh in the router and restarts openvpn client. I have to look into it | |

Do not know if setting nice will get you any extra performance, doubt it will Indeed a "normal" watchdog script just pings and if unsuccessful restarts Openvpn (or reboots the router) See fourth post in this thread: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=321686_________________Routers:Netgear R7000, R6400v1, R6400v2, EA6900 (XvortexCFE), E2000, E1200v1, WRT54GS v1.
