| will this access list modification prevent my internal DNS server from
| updates to it self from my telco's DNS server?
| 
| access-list 101 deny 53 any any
| access-list 101 deny 55 any any
| access-list 101 deny 77 any any
| access-list 101 deny 103 any any
| !--- insert any other previously applied ACL entries here
| !--- you must permit other protocols through to allow normal
| !--- traffic -- previously defined permit lists will work
| !--- or you may use the permit ip any any shown here
| access-list 101 permit ip any any
| 
| Thanks in advance
