Im new to CISCO ACL's.  I need to add my IP address ( to the ACL.  Below is the SHOW ACCESS-LIST command on the router.  What is the syntax to use if I want my IP on access-list 99.  Also, does this open all ports for these specific IP addresses?

access-list 70 deny   any
access-list 99 permit
access-list 99 permit
access-list 99 permit

Do I need to reset or renew the ACL after adding the new IP??
access-list 99 deny   any log

Type config t to configure from terminal.

test.com#config t

Enter configuration commands, one per line.  End with CNTL/Z.
Enter the interface that the dialer map IP line is under:

test.com(config)#access-list 99 permit
LVL 16

You can add your address by using this command:

access-list 99 permit 1192.168.100.110

It will append itself to the end.  If you want to delete an entry, that's a different story.  There is no need to "re-apply" or "reset".

Remember after you are done to type exit until your back at the first command line.  Then you want to type wr mem.  This writes it to memory, that way when you reboot it will still be saved.

test.com#wr mem
