RRAS 08 R2 IPSec L2TP Behind Sonicwall
Posted on 2012-08-30
I'm looking for a boost in terms of troubleshooting VPN connectivity issue. Due to recent vulnerability exposure, i'm trying to move my organization away from PPTP.
Currently, the box (an 08 R2 DC) runs RRAS and PPTP functions normally.
I set up IPsec with PSK via its own NPS Policy and here's what I'm seeing:
From LAN, i can connect without issue
From WAN, i cannot connect. Packet capture shows IKE traffic back and fourth, sonicwall confirms that no packets are dropped, all are forwarded. At this point, the client connection fails with error 809.
Ports opened (and natted) to the server on the SW:
Protocol 50 ESP
Side note: The Sonicwall runs a site-to-site VPN tunnel and also serves VPN (wan group VPN) The DC has a dedicated public IP
