My phone is plugged in the port 53 of our pabx, will I have to plug my phone in another port if I implement this access list ?
DNS is using port 53, I think you should consider unblockthis port if you want your DNS to communicate with your ISP DNS. 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
