two powerconnect 6248 VLAN Routing and Trunk-Port

Hello everybody,

I have two 6248. On the first switch I have configured VLAN 2-8. On the second switch I have configured VLAN 2 and 8. All VLANs are port-based VLANs. I have set the ip adresses on the VLAN interfaces and I have enabled globale routing and routing on the VLAN interfaces.

VLAN 8 is the connection between DSL Router and Firewall. The Firewall has two NICs VLAN8 / VLAN2.

See graphic:

Now I want that VLAN 3-7 have only access to VLAN2. How can I set the routes? Because if i want to set the route i get an error. And how can i create the trunk port between the switches (SFP Module)?

Regards and thanks for help.

PS: I hope you understand my bad english :)
