I am having a routing problem on a Juniper SSG-20.  I have recently been running out of IP addresses on my network and wanted to setup a seperate subnet for developement and test machines.  I have 2 interfaces boud to the the trust zone bg0 192.168.34.xxx/24 and 0/3 10.0.34.xxx/24.  I can communicate between both subnets without trouble but only the bg0 interface can connect to the internet.  I have 2 WAN interfaces 1/0 main high speed fiber connection and 4/0 a copper T1 connection for backup.

Below is the Destination routing table.  There are policies to allow Any traffice from Trust to Untrust.

Any Help would be greatly appreciated.

I'm not familiar with Juniper but given your situation, a few things come to mindt:
1. all devices have the Juniper as their default gateway
2. NAT/PAT configured for that subnet
3. security rules allow traffic from that subnet

I also noticed that all the other subnets have specific interfaces they're connected to except 192.168.34.0
What interfaces are included in that bridge group?
