Hi
I have been attempting to apply the following ACL to a VLAN interface on one of my 5406zl's without success. My scenario is:
I am using VLAN 100 for our servers vlan. I am attempting to limit access to servers based on specific TCP port requirements and in testing, I have test switch connected to one of the untagged ports in the vlan with an address of 10.64.44.10. I have been attempting to apply an acl to deny port 80 traffic from my internal network to this host and only allow port 443.
It appears that when I apply my ACL 100 to the vlan interface, on the switch that the test switch (10.64.44.10) is connected to, the acl doesnt work. If I apply it to the physical interface C5 that the network switch is connected to it works. I need to apply the acl to the vlan interface as I have a number of servers with differing tcp port requirements ( ie sql, web/ssh etc) and would like to control access on a vlan basis not per port. Am I missing something here in relation to the traffic flow? I have tried both in and out rules on the vlan interface without success and have also transposed the acl rule to have source/destination the other way around
vlan 100
name "VLAN100"
untagged C5,C14
tagged C20-C24
ip access-group "100" in
ip address 10.64.44.11 255.255.255.0
ip access-list extended "100"
10 deny tcp 10.64.44.10 0.0.0.0 10.64.0.0 0.0.255.255 eq 80 log
20 permit tcp 10.64.44.10 0.0.0.0 10.64.0.0 0.0.255.255 eq 443 log
exit
