Router behind Sophos UTM

Hi,

I have clients behind a router behind a sophos UTM which I am trying to get internet access but not sure where to go from here. My setup is below:

Sophos UTM

  • Connected to Modem (which connects to internet)
  • LAN IP address of 192.168.1.1/30 (internal interface)
  • I have setup static routing to point 192.168.2.0/24 to go to internal interface
  • Firewall - Allowed all (at this stage) to go 192.168.2.0/24 network
  • Firewall - Allowed all (at this stage) to come from 192.168.2.0/24 network
  • Masquerading - Added the 192.168.2.0/24 to external (WAN) primary address

Other Router (DDWRT)

  • WAN IP - 192.168.1.2/30
  • LAN IP - 192.168.2.1/24
  • DHCP - Clients get an IP within the 192.168.2.1/24 network
  • Firewall - Allow all traffic 
  • Router mode - Disabled NAT etc

Tests Completed

  • Sophos UTM
    • Can ping 192.168.2.1
    • Cannot ping 192.168.2.50 (client within 192.1682.0/24 network)
    • trace route to 192.168.2.50 goes to 192.168.1.1 then times out

  • DDWRT router
    • Can ping 8.8.8.8
    • Can ping 192.168.1.1
    • Can ping 192.168.2.50 
  • Clients on 192.168.2.0/24 network
    • cannot ping 8.8.8.8
    • cannot ping 192.168.1.1
    • trace route to 8.8.8.8 goes to 192.168.2.1 then times out
    • trace route to 192.168.1.1 goes to 192.168.2.1 then times out

I'm not sure what else to try. Can anyone see if I'm missing anything?
