Access control list configuration task list 61
OnSite Model 3210 User Manual 6 • Access control list configuration
Where the syntax is as following:
If you place a deny ip any any rule at the top of an access-list profile, no packets will pass regardless of the other
rules you defined.
Example: Create ICMP access control list entries
Select the access-list profile named WanRx and create the rules to filter all ICMP echo requests (as used by the
ping command).
3210(cfg)#profile acl WanRx
3210(pf-acl)[WanRx]#deny icmp any any type 8 code 0
3210(pf-acl)[WanRx]#exit
3210(cfg)#
