For the following models: mohinh accesslist

3 VLAN: (1,2,3) ip and information shown above

See the article here Access Control List 

Requirements:

1. You need to configure the same VLAN ( VLAN view article )

2. After you have configured the 1. We need to ban the PC in VLAN 2 (corresponding to 2 buildings) access on the Web site ServerO), while the other traffic operating normally

++++ The configuration steps:

1. Define ACL (after the show we see)

access-list 120 deny tcp 172.16.2.0 0.0.0.255 host 192.168.1.2 eq www
access-list 120 deny tcp 172.16.3.0 0.0.0.255 host 192.168.1.2 eq www
access-list 120 permit ip any any

2. Apply to the VLAN (on behalf of the port as a router)
