[2.1] Allow only specific users group access part of lan throug openVPN

[warpil]

I want to restrict access through OPENvpn for specific users
While through one will be accessible whole internal network - through second only partial resources are available. Also i have 2 users groups VPNALL and VPNR
So when users connects from group VPNALL - he recieves whole access, while if user from VPNR - only restricted…

How this may be done?

I thought about 2 VPN servers, but there is no option to choose for which user which server works...
