[j-nsp] Source Based Routing

[SunnyDay]

Hello I trying to configure source based routing on a ssg140. 

The ssg has 3 adsl lines 2 adsl cards and one bridged pppoe on an Ethernet.

I have put the interfaces to the untrust-vr and local network to the
trust-vr with the appropriate zones.

I have 4 subnets 192.168.10.1 192.168.20.1 192.168.30.1 192.168.40.1.

 I have configured a default route to the trust-vr pointing the untrust-vr.

At the untrust-vr I have source based routing e.g 192.168.10.0/24 to leave
through adsl/1.but this does not seem to work.

When I put the source based routing to the rust-vr traffic leaves for adsl/1
but internal traffic goes also.

Anyone has worked with similar scenario icould use some help here.

Thanks
