Strange ACL Behaviour

Hi all,

Please help with an annoying ACL issue. I have the following extended ACL configured but for some I still can’t get web access when the time range is active.

The email and other ports work perfectly but when the time range shows active in the router still no web access is possible on the controlled vlans and networks, any ideas?

Thanks

Louise

Hi

I cannot see any where the http or https traffic is allowed in the ACL.

Please allow traffic to port 80 and try.

Hi

The web traffic (http, 80 and https, 443) are allowed in lines 60 to 90 per subnet which inturn is controlled by the time range QQQ_Control, the Cisco IOS changes port 80 to www when you type it into the ACL.

60 permit tcp 192.168.2.0 0.0.0.255 eq www 443 8080 5190 1863 any time-range QQQ_Control

70 permit tcp 192.168.3.0 0.0.0.255 eq www 443 8080 5190 1863 any time-range QQQ_Control

80 permit tcp 192.168.6.0 0.0.0.255 eq www 443 8080 5190 1863 any time-range QQQ_Control

90 permit tcp 192.168.0.0 0.0.0.255 eq www 443 8080 5190 1863 any time-range QQQ_Control
