Firewall (inside ip 10.138.74.3)
Blue coat (10.138.74.5)
Now the problem is I am unble to access (ping) blue coat from user pc and access switch.It aslo not pingingfrom the access switch which is connected between blue coat and core switches.It's only pinging from from core switch.
In blue coat one default Route is there
to the firewall (10.138.74.3).
The access switch port which is connected to blue coat is configured under VLAN 50.Please find attachment for the core switch and access switch (connected between blue coat and core switch) configuration.
** from user PC I can able to ping the firewall and router but only blue coat is not pinging.
Please help to relolve this issue.
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.
