Configuring gateway mode
The gateway mode is a specific operating mode for 6600/HSR6600. It enables the router to provide
more than 10 G NAT performance, so the router can provide better gateway services for campus,
enterprise, and cybercafé networks.
On an 6600 router that has two MCP MPUs, after you enable or disable gateway mode on the active
MPU, the standby MPU automatically reboots to synchronize its operating mode to the active MPU.
