Hello! I was having troubles with the old version of Openvpn comunnity so I updated to 2.5.3. I uninstalled everything on my server (windows server 2016) deleted old files and installed the new version. I followed [url=https://github.com/OpenVPN/easy-rsa/blob/master/README.quickstart.md]this[/url] and created the ca.crt, ca.key, dh.pem, server and client's .key and .crt. Then I used the tls-auth section in [url=https://openvpn.net/community-resources/how-to/#hardening-openvpn-security]this[/url]. Just to test it, I disabled client, server and router's firewall all together. But the server doesn't even receive the connection attempt. [oconf=Server] port ***** proto udp # "dev tun" will create a routed IP tunnel, # "dev tap" will create an ethernet tunnel. dev tun dev-node TAP ca "C:\\OpenVPN\\config\\ca.crt" cert "C:\\OpenVPN\\config\\serverv2.crt" key "c:\\OpenVPN\\config\\serverv2.key" # This file should be kept secret dh "C:\\OpenVPN\\config\\dh.pem" topology subnet server 10.10.7.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "route 192.168.6.0 255.255.255.0" push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" tls-auth "C:\\OpenVPN\\config\\ta.key" 0 # This file is secret cipher AES-256-CBC # Enable compression on the VPN link and push the option to the client (v2.4+ only) compress lz4-v2 push "compress lz4-v2" status openvpn-status.log log openvpn.log verb 4 # Notify the client that when the server restarts so it can automatically reconnect. explicit-exit-notify 1 auth-nocache [/oconf] [oconf=client] client dev tun dev-node TAP proto udp remote x.x.x.x ***** # Keep trying indefinitely to resolve the host name of the OpenVPN server.

I tried restarting the VPN on the server and the client, reinstalling openvpn, and nothing works. The server doesn't show any signs of a client trying to connect, so I don't know where to start. Thanks in advance!

Port-forwarding on your router ..

I checked that too, and it seems to be all right: [list]The protocol is UDP[/list] [list]The port is the correct one[/list] [list]The destination local ip is the correct one[/list] [list]The WAN interface is the correct one[/list] I don't know whats wrong :(

If you are trying to connect to the WAN IP address of your external router from inside the LAN it may not work because not all routers support what is known as [i]hair-pinning[/i]. Try from somewhere else ..

Hi Tin, thanks for the info. Unfortunately, I'm not trying to connect from inside the LAN, I'm having the problem from a remote location. I hope you have another clue where I'm doing something wrong

Nope, that's all I have. If all else fails then you can contact me privately: tincantech at protonmail dot com (Fees will apply)

If oldopenvpn used to work and have some trouble so it is more easily to make it work on news version 2.5 on windows. Do you update both client and server to new version and remember you create new CA so you need up date new CA and certificate on client too. Just post log on both client and server so we can help you.

Hello Guys! I think I found the problem. The client was using UDP4 but the server UDP6. I "forced" UDP4 in the server config, but now I get this error when trying to connect to the server: [code] TCP/UDP: Socket bind failed on local address [AF_INET][undef]:***** Exiting due to fatal error Closing TUN/TAP interface NOTE: Release of DHCP-assigned IP address lease on TAP-Windows adapter failed: [b]Todavía no se ha asociado una dirección con el extremo de red.[/b] (code=1228) [/code] ***** is my port, and the bold text says something in the lines of "there isn't an address associated with the network end" Maybe you can help me a little bit more now

This is now a different problem and no doubt you have made many changes. The least we require is your complete config and log file.

I made only the change from "proto udp" to "proto udp4" on the server [oconf=server] port ***** proto udp4 dev tun dev-node TAP ca "C:\\OpenVPN\\config\\ca.crt" cert "C:\\OpenVPN\\config\\serverv2.crt" key "c:\\OpenVPN\\config\\serverv2.key" # This file should be kept secret dh "C:\\Program Files\\OpenVPN\\config\\dh.pem" topology subnet server 10.10.7.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "route 192.168.6.0 255.255.255.0" push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" tls-auth ta.key 0 cipher AES-256-CBC compress lz4-v2 push "compress lz4-v2" persist-key persist-tun status openvpn-status.log log openvpn.log verb 6 explicit-exit-notify 1 auth-nocache [/oconf] [olog=Log on Verb-6] 2021-08-12 11:42:41 WARNING: Compression for receiving enabled.
