Websense Email Security Gateway Interfaces handle traffic into and out of the Websense Email Security Gateway module. It is important that you set up interfaces E1, E2, and C correctly before deploying off-appliance components. TRITON Unified Security Center installation cannot complete unless these interfaces are correctly configured.
