The Blue Coat can maintain its default route to the Firewall, but you also need to add specific routes pointing to the core that includes the internal segment.


The Firewall is not a router so it will not redirect request back to the core when the Blue Coat sends its transmission reply from request originated from internal devices.


The only route the Blue Coat knows is towards the FW, it must also know routes toward the core and you must configure it to do so.

Hi,


Before the configuration was different ..


Internet Router

|

Firewall

|

Blue Coat

|

Access Swith (nothing was configured)

|

|(Access port-VLAN 50)

Core 2


In that Acces Switch nothing was configured.The Core Switch 2 port was configured under VLAN 50 whch was connected to Access Switch.For redundancy purpose I have changed the configuration same as posted earlier.

So according to you I need to add reverse route in blue coat.I will do it and update to you.


Thanks!!
