So I've got a SonicWall NSA 4500. I've set up a ton of these guys in the past, and there is always one thing that I end up running around trying to figure out, and sure enough I'm running into it right now.
So, we're using the Global VPN (not SSL-VPN). No problem connecting and accessing local resources. Now, I have this odd thing where SOMETIMES users can access the internet when connected, other times they can't. I don't make any change, I get a call that users on the VPN can't get out to the net. Next thing I know, I get a call saying it's all good.
So, My setup. The Sonicwall is passing out DHCP addresses in the 192.168.15.0 /24 range. My Local subnet is 192.168.10.0 /24. The sonicwall's LAN IP is in that subnet.
VPN items I have setup:
"Default Gateway" has IP 192.168.15.1 entered (although this IP does not exist?!)
Virtual Adapter Settings: DHCP Lease or manual Config
Allow access to: Split tunnels
Set Default Route as this Gateway is checked
