Configuration Examples for Permitting or Denying Network
Access
This section includes typical configuration examples for permitting or denying network access.
The following example adds a network object for inside server 1, performs static NAT for the server, and
enables access to from the outside for inside server 1.
hostname(config)# object network inside-server1
hostname(config)# host 10.1.1.1
hostname(config)# nat (inside,outside) static 209.165.201.12
hostname(config)# access-list outside_access extended permit tcp any object inside-server1
eq www
hostname(config)# access-group outside_access in interface outside
The following example allows all hosts to communicate between the inside and hr networks but only
specific hosts to access the outside network:
hostname(config)# access-list ANY extended permit ip any any
hostname(config)# access-list OUT extended permit ip host 209.168.200.3 any
hostname(config)# access-list OUT extended permit ip host 209.168.200.4 any
hostname(config)# access-group ANY in interface inside
hostname(config)# access-group ANY in interface hr
hostname(config)# access-group OUT out interface outside
For example, the following sample access list allows common EtherTypes originating on the inside
interface:
hostname(config)# access-list ETHER ethertype permit ipx
hostname(config)# access-list ETHER ethertype permit mpls-unicast
hostname(config)# access-group ETHER in interface inside
The following example allows some EtherTypes through the ASA, but it denies all others:
hostname(config)# access-list ETHER ethertype permit 0x1234
hostname(config)# access-list ETHER ethertype permit mpls-unicast
hostname(config)# access-group ETHER in interface inside
hostname(config)# access-group ETHER in interface outside
The following example denies traffic with EtherType 0x1256 but allows all others on both interfaces:
hostname(config)# access-list nonIP ethertype deny 1256
hostname(config)# access-list nonIP ethertype permit any
hostname(config)# access-group ETHER in interface inside
hostname(config)# access-group ETHER in interface outside
The following example uses object groups to permit specific traffic on the inside interface:
Purpose
Displays the current access list bound to the
interfaces.
