[44net] Openvpn security

Hi All, After following the list and seeing all the problems with security would someone like to give some reasonably detailed advice on what I should be doing to keep myself and others secure.Also what should I check is running from a security viewpoint Please remember that I am not an expert in either Linux or networking. A step by step how to would be really helpful both to me and presumably the rest of the network. My set up is simply a raspberry pi running openvpn set up as per the wiki. It connects OK but the only security I am aware of at my end is fail2ban running with very minimalist rules. The Pi has two Ethernet ports eth0 and eth1 and a wireless access, wlan1. The tunnel is tun0 What should I do to keep secure? I would also like to comment that the suggestion on the list recently about a basic raspberry pi SD card image for beginners like me, would at least let us participate without compromising the security of the whole network. I am sure it would also encourage greater participation as a whole Rgds Tony VK3API
