Connection Errors with SonicWall Firewalls

Some routers, like the SonicWall, have special features to prevent a type of internet attack called a “flood”. Unfortunately this introduces a delay that can cause issues when eKeypad is trying to make and SSL encrypted connection.

Specifically, the implementation used by SonicWall will cause SSL connection errors (Error code: -9806) in eKeypad. There are 2 options in the SonicWall router: “Always Proxy WAN Client Connections” and “Proxy when Suspected”. You must use the “Proxy when Suspected” option with eKeypad.
