Configuring ISP router and UTM SOPHOS v9

Question

Hi, This is the enviroment: ISP router lan IP 192.168.1.254 Sophos UTM Firewall 2 interfaces: 192.168.1.253 wan 192.168.154.70 lan 192.168.154.0/24 computer&acute;s lan Using the proxy(192.168.154.70) I can browse internet I can ping from lan to 192.168.1.253 but not 192.168.1.254 and not..for example www.google.es. This is not only the problem, lan computers need internet for outlook 2010, ftp etc. At firewall console, everything is green! 
 
 What is wrong? Regards

The MASQ rule needs to be LAN (Network)--->WAN. The way you have it, only traffic with the source of the internal address of the LAN interface will be natted, but no other traffic from your network. :)
