3com 4250T Switches Creating VLAN s with 802.1Q tagged connections - can I get traffic out on my Cisco 1702
This is similar to previous question that lrmoore answered so well..but I don't get to use Cisco switches..or even layer 3 switches.. trying to make this happen with Layer 2 3com switches...
So..a landlord is providing broadband to his tenants.
equipment:
Time Warner Telecom supplies a managed router that is dishing out a 10MB of pipe
My Cisco 1700 series router has (2) ethernet interfaces
My 3Com 4250T 48 port, layer 2 switches with support for 802.1q tagging
The goal:
Give broadband to tenants, but dont allow them to "see" one another on the network..just let them get out to the internet.
Tenant1 will be on VLAN1 on the 3com 4250T switch with an assigned IP of 192.168.1.100
Cisco 1700's FastEthernet 1 is also part of VLAN1
So Tenant1 wants to go to the web.. wouldn't that request get passed to the Cisco, which would route out to the Time Warner router and then out the door...assuming that the Tenant and the Cisco were part of the same VLAN?
thx,

This installation worked...was able to use ACL's on the Cisco router to restrict each IP address to only route out. Because of the frame tagging capability of the 802.1q 3com switches I was able to allow each VLAN to see the Cisco and get out to the web.
However, to make this even easier, I would suggest using Layer3 switches... I was using layer 2 switches... not by choice.
Please close this question.

I am planning on have the Cisco plugged into a port on the 3com switch that will be tagged with the 802.1q tagging and thus part of a port in the various VLANs I will create...
