I had a flat network setup with no VLANS. I need visitors to be able to plug in a laptop on my network, pull an IP from my DHCP server and access the internet. All without being able to touch my everyday user network. I don't want them to be able to access anything outside of the VLAN that will be configured for them. Can I accomplish this only using Nortel 4528's?

yepp, you have to inplement vlans, or more precisely - you have to create one more vlan and place visitors ports to it, as well as a firewall port (to provide visitors with dhcp and internet)

A firewall port? A specific port designated on the switch? How? Do you have a site where I can view documentation to set this up or instructions?

Thanks

I'm so sorry for my delayed response...Would this give one VLAN open access to all resources on the other VLAN and vice-a-versa?

What if i only wanted the 2nd (Vistor's) VLAN to access the internet, get an IP from the DHCP Server on the company's VLAN, but not access network server or desktops? Would I have to use ACL's and some type of rules setup on the switch? Hope I'm making sense here...

Hi,
no, in case of router on a stick scenario, your router will be given access to all vlans and it will be the place for filtering.
so there is no need to use ACLs on the switch, but only on firewall, which is designed to do filtering in a much better way then generic switch.
