Not hard, I have a box with 34 interfaces - 2 real, 32 VLAN. In this case it was built to allow a business centre to provide network services to it's tenants (each with an RFC1918 subnet, natted from the internet connection), whilst keeping each tenant from peeking around other networks. On a large campus, much larger routers are very easy to get - distributing multiple subnets to specific locations via VLAN configurations in switches. At work we have such a campus (a science/technology park) under our control. Each customers gets a small subnet, and it is managed by one router with a VLAN per customer/subnet. Traffic is shoved around the campus by gigabit fibre networks and multiple switches, with each customer restricted to their own connection by the VLAN configuration of the port they are physically connected to. 67 ports would not be unreasonable for our network there - I don't recall how many it actually has at the moment. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
