I have a small wireless ISP and all my customers have public static IPs. I am adding a /24 of new addresses to my network and need to have multiple VLANS on my 2950 port which is just an access port currently. Right now the current IPs are on VLAN 1 along with my client antennas that I manage which are on private statics. I want to add a VLAN (400 for example) but also need to have access to the old addresses and manage my client antennas. Is there a way to do this?
