Example 4.69. Permit TCP

access-list 100 permit tcp any any
access-list 100 deny any any
interface FastEthernet 0 access-group 100 in
interface Wireless 0 access-group 100 in

Example 4.70. Permit TCP for a subnetwork

access-list 100 permit tcp 192.168.1.0 0.0.0.255 any
access-list 100 deny any any
access-list 101 permit tcp any any state established,related
access-list 101 deny any any
interface FastEthernet 0 access-group 100 in
interface Wireless 0 access-group 101 in

Example 4.71. Open various TCP and UDP ports

access-list 100 permit tcp 192.168.1.0 0.0.0.255 any eq 80 state new
access-list 100 permit tcp 192.168.1.0 0.0.0.255 any eq 110 state new
access-list 100 permit tcp host 192.168.1.25 any eq 25 state new
access-list 100 deny any any
access-list 101 permit tcp any any state established,related
access-list 101 deny any any
interface FastEthernet 0 access-group 100 in
interface Wireless 0 access-group 101 in

Note

TCP rules are usually closed by the rule that permits all established and related packets, which
is necessary for handling TCP connections in most cases.
