cat <<EOF > $office_dir/README.txt

Notice:
   You have to change some configuration files becaus the because
   the configuration of network interfaces must not be equal.

   For the backup gateway host:
      eth1 --> LAN
      eth2 --> WAN or ppp0 (DSL device)

      eth0 --> WLAN or second LAN or what ever
      or
      br0  --> WLAN or second LAN or what ever


   So you have to change the following files
      dsl-provider.${_network}: ppp0 comes over eth2
      interfaces.${_network}: see above
      ipt-firewall.${_network}: LAN device (mostly $local_if_1) = eth1
                    second LAN WLAN or what ever (if present) = eth0
