Issue/Introduction

When deploying transparent proxy using WCCP with L2 forwarding or deploying the ProxySG in default gateway mode, the device will not forward any traffic that is destined to its MAC address but not its IP address except for traffic on ports that are set to intercept. In order to allow the ProxySG to forward bypassed traffic in this scenario, 'IP Forwarding' must be enabled.

*This does not apply to inline/bridge mode.

 

Resolution

See the following KB article for more information on the 'IP Forwarding' feature and how to enable it:
