Access-List Help

i hav the network like this........

Internet Router----->ASA------>3750

now on 3750 i hav created 5 vlans, ASA will be a part of 1 vlan in 3750, rest 4 vlans will be on LAN.

my requirement is......

all the 4 vlans users in LAN should be accessed based on the rules applied in ASA & not in 3750.

which means all the routing should happen via ASA & not 3750, but VLAN should be created only in 3750.

I have this problem too.

Create L2 VLANs on the 3750.

Then create Subinterfaces on the ASA & configure IPs on all the subinterfaces.

Trunk the interface on the 3750 which is connected to thew ASA.

After this the users default gateway should be pointed to the subinterface IP on the ASA depending on whichever VLAN they are in
