ASA5510 with IPS module and 3750G stacked switches. Everything is working normal...so we introduced two new Barracuda devices inline (Web Filter and IM Filter) on the same subnet at the 3750 Core switch and the ASA Inside interface. Here's where it gets fun. Switch can ping the ASA, and pass traffic to the Internet just fine, through the two Barracuda devices. The two Barracuda devices can ping each other, but cannot ping the ASA or the switch. Neither the switch nor the ASA can ping either Barracuda device.
Switch - 10.1.200.1/28
ASA inside - 10.1.200.2/28
CudaA - 10.1.200.10/28
CudaB - 10.1.200.11/28
Have tried defaulting the gateway for the Cuda's to either switch or ASA without success. Both Cuda's work on two separate networks in this same design and inline placement (one behind a PIX and before a switch and the other behind an ASA5505 and before a switch). Have tried intra-interface traffic allowing and not and have talked to both the LAN switching team and ASA team at TAC...neither of which seems to find anything.
