Tomato Shibby vlan

Hi,

Perhaps You can Help me.
I have a Asus ac66u with latest Shibby 1.40

I have a DSL Modem that have IP 169.254.2.1 but only
accesable in lan port 2. Asus wan port to lan port 1 on Modem.

My idea was Put a lan cable in Asus port 4 and Modem port 2.
Set port 4 a new vlan with IP 169.254.2.10 so that i can Access the
Modem over 169.254.2.1, also remote and so on.

Doesnt Work. I Tried everything.. now i reset all again.

Have anyone a simple Tip for me how can i Realize that?

Thanks and...
