Issue with VLANs & Trunk with 2801, Cat 500 & Cat 3524
I'm trying to create a trunk link with my Cat Express 500 and Cat 3524 with the 2801 routing for all vlans.
I currently have 2 VLANs for data and voice for my production environment on the 500 switch and everything works fine.
I added a sperate VLAN on the 500 for LAB stuff. I needed the 3524 for expansion of my LAB and have the ability to do PoE.
I got everything configured the way I think it should work - I plug the 3524 into its trunk port on the 500 and it goes thru the Blocking, Listening, Forwarding, ect, of Spanning Tree - then when the port goes active everything seems to be working fine.
But its not. I can ping from every VLAN to the router and between VLANS (where is allowed) but I cannot get to the internet. Not from workstations on any vlan - or from the router CLI itself.
And when I unplug the 3524 from the 500 everything, including the internet, starts working again.
Let me know if any of you have any idea's as to what is going on - I am fresh out of idea's.

I have fixed my problem.
It turns out the problem was how I had the WAN.
I have a "Border" 1712 router if you will, where my ISP line comes in.
The reason for this is because they gave me one static IP - and then a pool of addresses - and they are on different subnets. So I have to route my traffic to the gateway of the static address. It is really retarded but we are dealing with it.
Anyway - I guess when I plugged the 3524 switch into the trunk line it messed up the trunk with the 1712 border router.
I am no longer switching that connection, it is plugged directly into the 2801 router. Everything seems to be working fine.
