Access List, bandwidth management and VOIP on a Cisco 1721 router for internet cafe
Posted on 2006-04-05
I am setting up an internet Café with 20 computers and a Microsoft ISA server in internal network, serving as caching proxy server only, and all tied together in a 50-Port unmanaged Ethernet Network Switch.
My WAN Circuit is 128K/64K SCPC Space Segment W/ Teleport
I am new to Cisco and I need to implement the following in a Cisco 1721 edge Router:
VOIP for 2 telephone ports
I have these 2 options for my access list:
Access-list 100 permit ip [internal network] [mask] any
Access-list 100 deny ip any any log
Access-list 100 permit tcp any any established
Access-list 100 permit udp host [external DNS] any eq domain
Access-list 100 permit udp host [external DNS] any gt 1023
Access-list 100 permit tcp [internal network] [mask] any eq ftp-data
Access-list 100 permit tcp [internal network] [mask] any eq ftp
Access-list 100 permit tcp [internal network] [mask] any eq http
Access-list 100 deny any any
Which of these includes all the traffic I need to flow in and out?
What Cisco IOS configuration do I need at the router to ensure end-to-end prioritization of calls, as for as bandwidth management is concerned, and considering my low budget WAN circuit for 20 computers and 2 VOIP ports?
