OpenVPN causing internet connectivity issues on end users.

ithelpdesk

We have a OpenVPN server on premises that has been working normally. However over the last couple days, today especially users have started losing connections to the internet while connected/connecting to or after connecting to our VPN.

For some reason (randomly, it appears) when a user connects to the VPN the internet will stop working. And then after that the internet stays not connecting, even after disconnecting from the VPN. The connection still says that it is connected and has internet access but almost no programs or browsers can access the internet. Unless it was already connected and being utilized. I've had it where I've remoted into a PC, then all the internet access goes away from all the different programs, and it still says connected and internet access. But somehow I am still connected to the PC via Teamviewer. But nothing else works.

The only way to get the PC to reconnect is to go through and restart the PC or in most cases do a Network Reset in Windows 10 settings and restart. The PC I have on me is doing it aswell. I've connected via Wi-Fi and Ethernet and connected to the VPN. It works and I disconnect, and repeat. Until I try to access the internet while using the VPN, then the connection breaks. If I exit the connection stays broken and I can no longer even reach the VPN host.

Any idea how to troubleshoot this further or see what is causing the issue? I cannot find any differences or changes in the network settings on the PC after it does this. Everything acts like it should be working and connected, but doesnt. Appreciate any help!

Thanks for the response. I apologize, I missed the initial how-to post. Have added verb 4 to the server config and restarted.

Here are some of the things needed. This system is sort of a relic and has basically just been maintained since I took over. So I'm not great with linux or too familiar with server or the openvpn setup. Do you know where the server log file is located? var/log has some files but there are several different log files. I thought it would be the syslog, but this has a lot of usernames, and doesnt seem to match the how-to example.

See --log in the manual.

If you need help doing your job then I am available for hire.

I've added the server log to my second post.

And I wasn't asking for you to do my job. I was just telling you that to inform you I wasn't the one that initially set this server up. I apologize if I've done something to make it seem like I'm not trying to do my research. But I came here to learn from people who clearly know more about OpenVPN then I do.

eurephia is a separate product with it's own support.

built on Dec 1 2014 is Old indeed .. and probably vulnerable to some nasty CVEs

ithelpdesk wrote I'm not great with linux

Seems like that would be a crucial skill ..

ithelpdesk wrote or too familiar with server or the openvpn setup

Start with the howto .. like we all do.

It is your server in your environment, all we can help with is openvpn and according to your logs the only issue I can see is:

ithelpdesk wrote Options error: --dhcp-option: unknown option type 'SEARCH' or missing parameter

See --dhcp-option in the manual. This may be a eurephia option ..

Also, your client is on the rusty edge of a blunt knife:

Lots of work ahead, my offer still stands.

300000

a sort of not register dns on windows so windows doesn't update its ip that is connection lost .there is two way to do it one from server and one from client

on the server config add

push "register-dns"

on client config just add

register-dns

when you make connection to server window will renew its dns server so it should work for you.

Ok I will try this. thank you for trying to help!
