I have been through 10+ tutorials on setting up a OpenVPN, and each tutorial gives a different problem…
Does anyone know of a decent and helpful website/tutorial which I could go to to get it set up? I have been battling through it for almost 2 months now.
Yes, I have also bugged forums.openvpn, but I think I have “reached my post limit” with them.
I have to configure it remotely via ssh.
okay, I have been asked to be more clear on the topic
I followed this tutorial (as a example) –
I had no issues setting up, etc. except when I boot into windows and run the OpenVPN GUI Client, it connects and gives this error:
WARNING: Bad encapsulated packet length from peer (21331), which must be > 0 and <= 1576 — please ensure that –tun-mtu or –link-mtu is equal on both peers — this condition could also indicate a possible active attack on the TCP link — [Attemping restart…]
Here is my server config:
port 1194 #- port proto udp #- protocol dev tun tun-mtu 1500 tun-mtu-extra 32 mssfix 1450 reneg-sec 0 ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt cert /etc/openvpn/easy-rsa/2.0/keys/server.crt key /etc/openvpn/easy-rsa/2.0/keys/server.key dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem plugin /usr/lib64/openvpn/plugin/lib/openvpn-auth-pam.so /etc/pam.d/login #- Co$ #plugin /etc/openvpn/radiusplugin.so /etc/openvpn/radiusplugin.cnf #- Uncomment$ client-cert-not-required username-as-common-name server 10.8.0.0 255.255.255.0 push "redirect-gateway def1" push "dhcp-option DNS 18.104.22.168" push "dhcp-option DNS 22.214.171.124" keepalive 5 30 comp-lzo persist-key persist-tun status 1194.log verb 3
and my client config:

So I dont know what I am doing wrong but I am getting a bit impatient and on each forum I post this, I get stupid/unrelated/unhelpful answers…

If you have specific issue, then say it. Being blurry is not any help.
