Hello

I bought a 24port tag based vlan switch to be able to control every 
ports access to each other and to the internet. Say I set up 20 vlans 
(each with a different subnet) and I want to let them only connect to 
the internet...

What I'd need is a "allow TCP/UDP from VLANx to WAN" rule. But since 
this doesn't seem to exist I'd have to add 19 rules to each vlan to 
block access to the others and one rule to allow all other TCP/UDP !?

Why isn't there a WAN in the destination list?
Or is there another solution?

thanks
