Does the Web Gateway 8450 or 8490 applaince in Inline or Inline + Proxy mode support connecting directly to another inline device?
At this time the Web Gateway 8450 and 8490 appliances only support directly connecting either 2 network segments (switch-router or switch-switch), or an endpoint device (such as a proxy server) to a network switch, as described in the Implementation Guide.
Symantec has not tested and will not support deploying SWG in an INLINE mode in series with other INLINE devices.
