Funny to say, but it's hard to setup insecure VPN. In this case I have router running under OpenWRT with 4MB flash only so it's only possible to include "openvpn-nossl" in firmware. That was easy part, but hard part was to find out what configuration I need to use to avoid SSL usage as I really don't want to compile my own openvpn package on server.

As I find out that is almost no information on internet about this use case, but after few hours of google-fu and source reading I finally setup configuration that actually work. There is none important data going to be transferred over network and security unimportant. Though I wish to add some basic PAM authentification in future, but for now it's not really needed.
