{{tag>Setup Broadband Configuration Cisco Cisco_IOS}}
====== Setting up SureVoIP Broadband on Cisco ADSL Router ======
This guide will apply in general to all Cisco routers with a built-in ADSL modem.

It is assumed you require only basic NAT and the ADSL service is your only internet connection. If your requirements require a more complex set up then please consult an Authorised Cisco Partner for further advice.

Please note regarding the sample configuration below:
  * Does //not// provide DHCP service to LAN
  * London time zone with BST set
  * Uses SureVoIP DNS servers
  * Basic NAT
  * IPv6 disabled
