Multiple WANs + Transparent Proxy

[Tucz0]

Hi All,
I have a strange situation:
1 - I have a box with 3 wans (1 - corporative + 1 - DSL)
2 - I use Transparent Proxy
3 - I want make the web traffic goes to DSL
4 - The default gateway is the corporative link

Question
How do I create a rule to make the web traffic out via DSL if the connection don´t start from my LAN but from my box (squid)?

Only possible in 1.3 or the special build of 1.2 for traffic shaping!

I can´t do this via command line? Create a rule to redirect the web traffic starting from localhost?
