We are upgrading our domain to Windows server 2008 R2 and I was wondering if anyone here has ever tried to make a directaccess server run RRAS so that you could also support standard VPN clients as well
DirectAccess server, must have two public static IPv4 addresses. Than it uses HTTPS protocol to establish connection. Also, after VPN is up-and-running, it uses only IPv6 for VPN, so you might need some of 6-to-4 technologies.
Yes, it is possible to have standard VPN PPTP or IPsec on same RRAS server where is DirectAcces, because it uses different ports/protocols in parallel :)
