Cisco Firewall configure question

[singapork]

Hey there i would like to know whether it is possible to configure the "inside interface" of cisco router with /24 subnet, which is connected to a layer 3 switch which has few network segment using /23 subnet...would it cause routing conflict?

FIREWALL "inside" interface (192.168.150.0/24) |----->LAYER 3 SWITCH------->internal network, 192.168.10.0/23 192.168.100.0/24

hmm; *IF* there's one connection from the Cisco to the switch which then provides the fan-out into the x.100.0/24, then the rules would be generic filters; high level, non-destination ip specific (no layer 2,3 rules)

there should not be problems with that approach.

Think of the Cisco as a gateway filter and then the L3 Switch as the low level controller.
