I have two segments in 6500 FWSM module in routed mode, Vlan A and Vlan B with same security level of 70. I want to allow IP traffic from A to B and Vice versa.
a. I have "same-security-traffic permit inter-interface" in config. DO I still have to use ACL to permit traffic between these VLANs? Does it not allow traffic to pass between interfaces with same security level ?
b. In case if I have to use ACL,and If I have an ACL which permits traffic from VLAN A to VLAN B, Do I have to have a reverse ACL rules as well ? ( If it is a statefull firewall, this should not be the case I guess.)
