(First question, please be patient)
We have a SonicWall NSA-2400 appliance as our firewall within our primary location. (SonicOS Enhanced 188.8.131.52-17o)
Remotely we have 2 sites with Cisco 2800 routers.
We have a working VPN between the SonicWall and the individual remotes, but machines at the remote locations are unable to authenticate with the PDC that is located in our main facility behind the SonicWall.
Devices at the remote location can ping anything behind the Sonicwall, but the windows Auth continues to fail.
Primary site (10.0.0.x) Remote A (10.0.5.x) : Can access anything on 10.0.0.x Remote B (10.0.6.x) : Can access anything on 10.0.0.x
What am I missing? Seems familiar to the old 'Black Hole Router' problem where you had to adjust the MTU setting to something <1500. thx
