 += Forwarding DNS Server =
 +This is the installation of bind on SLES 11 to create a forwarding DNS Server. This is installed on the [[squid|proxy server]] since that is the only server which has internet access. The main DNS servers (which handle the internal domain) will then use this DNS server as their forwarding server.
  
 += Installation Bind =
 +Go to yast -> Network Services -> DNS Server. If this is the first time it will prompt you that bind needs to be installed. This is of course no problem since we use an [[slesinstallationupdateserver11|update server]], so follow the prompts to do so.
 +
