[SOLVED] Can't get a route to Internet with L3 IE Switch

[dkellyusi]

Hey all!  My head hurts from trying to figure this out.

I have an L3 Core Switch (Allen Bradley 5400 running IOS)

I have several VLAN's, one of which is Management (vlan 10) where I can plug in my laptop to access all other VLAN's and their devices using the VLAN10 interface IP (192.168.10.1) as the gateway.  All of that works.  The problem exists when I try to access the internet from my laptop on the Management VLAN.  I can't get a ping through, I have confirmed that the Router IP I have set on ESXC2101 is valid (192.168.1.1)

Note: I can access the internet from ESXC2101 (I can ping 8.8.8.8, etc.)

I have attached my config.  I am totally lost as to why this isn't working.

Thanks in advance.  I'm sure it's something stupid, and I've just been messing with this for too long.

Dan

Hi,

Is the default gateway connected to interface Gi1/1? Is interface gi1./1 up up? Can you ping the gateway form the router. You might need a  crossover cable between gateway and your switch.

Thanks

John

Thanks for your reply, John

Yes, gateway is plugged into Gi1/1, interface is up, and I can ping the gateway 192.168.1.1 from the router.  I can also ping external IPs from the router (e.g. 8.8.8.8) which means that the gateway is working, too.  So puzzling.

Hi,

Does the gateway know how to get back to the 192.168.10.0/24 network? e.g. can you ping 192.168.10.1 from the gateway. You may need  static routes on gateway for networks on the switch.

Thanks

John

[dkellyusi]

Thanks to you both!  I knew it was something dumb I was overlooking.

I added a static route to 192.168.10.0/24 via 192.168.1.254 on my Gateway device (192.168.1.1).

Thanks again!

Maybe not so puzzling.  How does your internet (dsl ??) router know where 192.168.10.x is?   I would suspect you can't even ping the internet gateway itself from your management vlan 10.  Packets are making it TO the Internet router; but no way back.

I don't know if you have the capability of adding a static route on the Internet router?
