Game not working

[alakin]

Anyway I made a VPN server on my windows 64 machine to play game called "generals zero hour"
The guy connected to my server. We both got IPs assigned.
Yet when we go in game we can't see each other(lan lobby).

BUT we can see each other if we use hamachi. What went wrong?

I replaced actual IPs with (my ip) and (his ip).
I also wonder if disabling compression worked. Should I write comp-lzo no or just ;comp-lzo?

Also I wonder if instead of making several files for every client possible to make just 1 for all clients? like vpnbook does.

[alakin]

My goal is to make a server with no auth no compression and no encryption. Just pure simple transparent channel.
Give all clients one same .ovpn file so they can all connect and we play in lan.
Very simple and no hassle kind of thing.

[alakin]

You will require a minimum level of security, like a shared key.

This is better for games, due to broadcast packets:
http://openvpn.net/index.php/open-sourc ... dging.html

Follow the instructions and you should have no trouble.

Some other things:
post33633.html
topic13964.html

Bridge mode instead of routed mode is better?
What about the broadcast packets?

[alakin]

So will I be able to give ONE file to all clients and they all will connect and play? Or I need to make different files for each person?

[alakin]

Also the way to disable compression is by not having comp-lzo in the config file?

[alakin]

So will I be able to give ONE file to all clients and they all will connect and play? Or I need to make different files for each person?

Much better to have certs for each machine.

Well I wouldn't be so sure that it's best in my case. How do I make it with just 1 configuration file for all clients?
If it's not possible with 1 file for all clients then how do I make 1 file for each client but only 1 file and not 4 (.key, cert, ,ca etc).

[alakin]

For a very simple setup, that you seem to require, you can use one cert/key file set by issuing this directive in your server config:

Code: Select all

duplicate-cn

Code: Select all

--duplicate-cn
              Allow  multiple clients with the same common name to concurrently connect.  In the
              absence of this option, OpenVPN will disconnect a client instance upon  connection
              of a new client having the same common name.

All your clients will be able to connect concurrently using one set of certs and keys. It is not recommended, it will save you time but you could experience problems in the long run. You choose, it is your security.

That's cool but how do I make it with only one file instead of several? The vpnbook had it. One .ovpn file. I want to be able to have just one .ovpn file for all clients instead of many.

[alakin]

As for security I make server we play and then I close it so that's kind of obsolete

[alakin]

I get that but how do I make it so that I must give only 1 file to the client instead of several?
I don't want to generate .cer files etc I just want to give one .ovpn file and thats it. How do I make it so?
