Hi all, after reading some info here and there, I finally put my VPN up and running.
Some sites are using IPSEC, and others with big latency are using OpenVPN. So I wrote a wiki about it (OpenVPN part). I hope this helps beginners to deal with OpenVPN Site-To-Site: http://devwiki.pfsense.org/OpenVPNSiteToSite Please, are everyone free to correct typos and mistakes. Best Regards, Luiz Vaz
