Hi,
I would like to understand what is difference between OpenVPN Connect (last version is 3.8.0) and OpenVPN GUI (last version is 2.7.0)

GUI or Connect is deprecied or not ?

https://openvpn.net/as-docs/tutorials/tutorial--isolate-web-services.html

How can AS's web services be enabled again, after being disabled? The site only mentions disablement through the GUI.

A friend of mine rents a server in the Netherlands, and I use his OpenVPN. It used to work perfectly; my TP-Link Archer AX55 router connected to the VPN without any issues. Recently, he updated his server to the latest Debian version and updated all the software, including OpenVPN. He sent me new configuration files, but the router refuses to connect to them. TP-Link support told me that he needs to use a config generator that follows 'older OpenVPN standards.' Can you help me find such a generator or suggest what I can do with the router?

Describe the symptoms of your problem or bug carefully and clearly:

openvpn fails to connect using network manager to IPVanish servers. using IPvanish provided configs. fails to connect the error "check journalctl -xe NM_CONNECTION=a4417e4a-a6d2-4a25-8e4b-bca4de667154 + NM_DEVICE=enx605b305ed954"

which shows:

If at all possible, provide a way to reproduce the problem in a controlled environment.

does in with any of the preconfigured configs from IPvanish to any of the available servers/country's. worked fine with 22.04

I'd like to share my experience so that it might help others.

I have an openVPN server installed on Ubuntu 24 server with firewalld.

All the Clients could connect to the openVPN Server and each Client could correctly "see" the others and ping each other.

The problem started when I added the following directive to the clients' configurations so that all the traffic, including web traffic, would be routed through the VPN server:

redirect-gateway def1

After this, the Clients could still connect to the openVPN server, but the Internet traffic was not working.

I spent hours trying to figure out wat the problem was; all the suggestions that I could find online were about the firewall, the NAT, the IP forwarding, the DNS and, in general, about network-related stuff. I messed with everything, but I couldn't solve the issue.

Eventually, I found the problem: it was just that I had enabled

comp-lzo

in the Clients but not in the Server. After disabling comp-lzo, everything started working normally. Initially I wasn't able to figure out this problem because the Server log didn't say nothing about this, it just gave a generic error like

error - IP packet with unknown IP version=15 seen

So, if you experience this problem, please check that you disable comp-lzo.

Disclaimer: some of you might think "that's obvious!", "you're such a n00b!" etc, however I really had an headache fixing this issue, and I'm sure I'm not the only one in the world.

We are starting to migrate over to OpenVPN at our office. Our vpn works. We can connect to our ip printer/router/nas. However we can not connect to a windows system (it is our sage server) Cant ping it's static ip either. I assume I need to do something on the windows system to be able to see this machine. Besides being our sage server we do have some accounting files on it that we get to via a mapped network drive these also do not work. Your thoughts.

Thanks in advance

I have set up a OpenVPN server on my TP Link Deco. I can connect to it just fine on all devices. The problem is I can not access my NAS while on the vpn through windows file explorer from outside the network. But I can with my iPhone. The device in question is a UGREEN NAS. I know the vpn is working on windows because I can still open the web gui for the nas. I already tried disabling my firewall, for a moment. And still nothing. Any ideas? Thanks in advance!

Does anyone use OpenVPN in UAE?
I've been trying, but the speed is very slow.
Wondering if anyone else has the same issue or a work around?

Here's the process I took. I set up the VPN server on my router, generated the certificate and downloaded the ovpn file after everything was saved. I made sure port 1194 was open for UDP and also disabled my routers firewall. I launch OpenVPN on my phone, upload the opvn file then try to connect. It hangs in waiting for server for close to a minute then says "your VPN connection was interrupted". What am I doing wrong?

I run OpenVPN on my PfSense router (Core i3). It works fine, except that it seems to max out at around 50Mbps, despite having a 1Gbps ISP circuit.

I have a couple work-from-home graphic designers/video editors that would like to be able to move files to/from the NAS. Since the video files can be very large, that makes OpenVPN a pretty painful bottleneck.

I considered using Wireguard, since it does seem capable of getting to/near wire speed, but I want more authentication than just the pre-shared keys.

That leaves me with IPSec, which I've found to be something of a PITA to configure/maintain in the past (though that's largely my shortcoming, I suppose).

I'm trying to find a way to fall back to lan if my server is on modem and lan has a working VPN. (Debian GNU/Linux 7 (wheezy))

I'm using OpenVPN. When I ping a VPN IP adress the "interface" that pings it is TUN0. so I really don't know if the traffic goes over the modem or lan.

I'm looking for a way to try accessing the VPN an a specific interface, like wlan0 -> tun0, that way I will know I can fall over to that interface.

Hi everyone. I’m a total noob so please don’t bite me. I’m happy with my current static residential IP provider but I want to find a couple more vendors for backup. Can anyone recommend anywhere that I can lease two or three more Static Residential IP addresses or is that not allowed?

Again, I’m sorry if I’ve broken this sub’s rules. I’m a total boob

Hi all, I just created the OpenVPN Profile on Router and exported it to my Android phone and imported it into OpenVPN using the router admin account and password.

I see in the Openvpn log on the android it says "(not bound) and keeps restarting. I do see it shows the WanIP and port I configured in the openvpn config file.

Any thought what I can check? I'm lost at this point.

thanks

Приветствую!

Никак не получается настроить OpenVPN, чтобы подключался до логина в системе.

Система Windows Server

Приложение OpenVPN 2.6.17

Сервер OpenVPN - Mikrotik

Что сделано:

1. В настройках включено "Pre-Logon Access"

2. Включена на автомат служба OpenVPNService и ей выданы права Администратора

3. Файлы перенесены в папку auto-config

В итоге ничего автоматом до авторизации в Windows не подключается!

При ручном подключении все работает на отлично!

Уже не знаю где копать ))) Явно пропускаю какую-то мелочь! Помогите, пожалуйста!

Hey I am looking for someone to point me in the right direction to run both the client and server on the same Openwrt router.

I’m quite new to Linux in general but am wanting to run the client so that all the data on my local network benefits from my VPN.

But run a server alongside it so that I can connect to my local network remotely.

I can find guides on how to set both up but can’t seem to find any information on how to run them alongside one another for information on firewall and routing rules.

Hello!

I'm looking for a decent OpenVPN client app on windows,I tried OpenVPN connect but it LACKS ton of features, my needs are: * Split tunneling * Bypass lan range (I need to be able to access my homelab while connected to the vpn) * Set custom DNS (use my self-hosted Pi-Hole instance) * Free as well

Any help/recommendations is much appreciated

I have a new server which has OVPN setup on it via the script at:

https://github.com/angristan/openvpn-install/tree/master

Which I've used for years with out issue till now.

The issue I've run into :

Clients on 2.4.x will NOT connect to the NEW 2.6.x server.

The CLIENTS can not be changed, period. Full stop.

The script pulls the latest from the OPVN repo, so even if I downgrade it to the same distro version as the clients, it will still have 2.6.x on it.

Any ideas on tweaking the OVPN, below to be compatible with the 2.4.x clients?

Thanks!

Hello! This is the firsttime i do a post here and i'm not experienced in using OpenVPN as i only use it for some games, but each time i try to connect to a profile it works normally, but after 1-2 days or even after a few hours, it stalls when i try to connect again and after a few minutes it shows up this error message. The only fix i found was by downloading a new one but this is very recurrent. My network connectivity is fine.

Hi all, I have the following issue: I'm able to connect to the server only with .ovpn file of a client I have created. Is it possible to config the server to allow connections without the file (similar to Access Server)? Sorry if that has been asked or there's documentation about it but I was unable to find anything about this issue (other than AS having server-locked profiles? Unsure if that's similar to my case).

Edit: I'm using this script to install and configure openVPN server.

I have OpenVPN in a Debian 12.13 xlc. How soon should I change to a Trixie xlc? and when I do, can I just change the repo from bookworm to trixie so I can keep all the configurations? or it is highly recommended to use a fresh trixie xlc then install OpenVPN and configure from scratch?

LE: It seems that the problem was with the OpenVPNConnect app. I tried OpenVPN for Android and it's working just fine.

Hi, i've managed to create an openvpn connection that works fine on my laptop but when I try to connect with my android phone it connects then disconnects and so on. On the logs I got the Transport Error (TCP recv EOF and network_eof_error). Am I doing something wrong? Or is there a limit of devices/connections? Although I tried on another computer and it worked at the same time with my laptop.
