|It appears that I am going to need to start using VLANs but I have no idea where to start. This is what I have going on:|
2 Outer Offices - I've read that it's a good idea to put outer offices on a VLAN. Why? These offices don't have domain controllers, they're still small yet. We don't have a site to site VPN set up yet at one of the offices, users connect to our Terminal Server to do their work. When we do set up the VPN users will still need to use Terminal Services because our main app won't run over a VPN.
The other office is connected via fiber cable from the switch in the office to a switch in my main office.
IP Phones - I was told to set up a VLAN for our IP Phones. Where to start?
We're about to set up an iSCSI SAN. I was told a VLAN is best practice here too.
I'm pretty sure that my switches allow me to select a port and add it to a VLAN, but I think the subnet needs to be created in Active Directory (Server 2003) and DHCP needs to supply the addresses. How do I do that? Also, do the VLANs need to run independent of our primary subnet or do they need to be linked? How do I do that?
Yet another idea, because we use NIC Teaming each server on my network will need 3 IP addresses (NIC Teaming - one for each physical NIC and an addressable one for the NIC Team) We have a single subnet in which a block of IP's was set aside for the servers. My problem, for example, is that IP addresses 1 - 20 are for servers, 21-50 are for users with static IP addresses. Addresses 1-20 doesn't provide enough space for my servers when each one is using 3 IP addresses. And sliding the users on addresses 21-50 down is a lot of work. Does it make sense to put my servers on a VLAN? Related, but unrelated - Active Directory doesn't recognize that IP Address ending in 3 is being used by a NIC Team. Does that mean I this address only serves as a placeholder in the Teaming software and can be used on another server where it can be addressed? Can I use the same placeholder IPs in all of my NIC teams?
Thanks for taking the time to read and reply.
