Configurar VPN RoadWarrior Client-Server

Installed OpenVPN from software center,
goto Gateway → OpenVPN roadwarrior
Checked → Enable roadwarrior server
choosed Username, password and certificate
Mode → Routed mode
Entered desired IP network for VPN
Entered desired Netmask for VPN
[advanced] → checked Push all static routes
[advanced] → DHCP options → enter domain name and local DNS server IP
[Connection parameters] → enter your external IP address / or external dns name
After that I installed LDAP account provider
created new user + password
go back to Gateway → OpenVPN roadwarrior
second tab → Roadwarriors account → Create new
choosed System user → submit
go back to Roadwarriors account → on user use Action and Downloaded listed files
OpenVPN client on Windows/Linux works very well with that
