I have tried a few different things but I am unable to get it to work. It worked at one point but after a re-install it is no longer working.

On a 3801HGV I used the following settings with 5 static IP addresses

Connect WAN connection on Sohpos to a port on the Uverse router

On the ATT 3801HGV Uverse router

  1. Go to Settings > LAN > IP Address Allocation
  2. Configure Settings for MAC address on firewall
    1. Firewall - Enabled
    2. Address Assignment - Private from Pool
    3. WAN IP Mapping - Router WAN IP Address
    4. Cascaded Router - Yes
  3. Go to Settings > Firewall > Applications, Pinholes and DMZ

On the Sophos Firewall

  1. Configure WAN connection for DHCP
    • It will configure your wan connection for an internal IP address, but don't worry it will route correctly
  2. Disable Web Filtering if you want browsing to come from different addresses
  3. Configure Additional Addresses
  4. Configure Masquerading
