I am setting up a voip lab. I have 1 cisco 3560 switch. 1 2811 router. 1 pc and 1 esxi server.  The esxi server is on a different subnet but for some reason I cant ping it from the switch or the pc. I can from the router though. Most of the network is 10.10 but the exsi is on the 192 network. Below are my configs. I don't want to change any of the ip info or config. Just want to make it work the way it is.

- Have you tried adding the <ip routing> command to the 2811?

or

if it already has that command, try negating it

no ip routing

play around with that and see

ip route 192.168.15.10 255.255.255.255 192.168.15.0
delete it

Data pool don't need option 150

pc can ping 192.168.15.1
What is 192.168.15.10 default gateway?

ip default-gateway 192.168.15.20 looks wrong, but that should not have any influence on problem.

Everything looks OK.
Routes are in routing table. Directly connected interfaces, there should not be any problem.
Host can ping router and router interface 192.168.15.1. Router can ping esxi server.
If exsi server is 192.168.15.10 I guess that that ip address should be in excluded addresses.

If subnet masks are OK, I don't see reason for configuration not to work.

The only thing that I can think of trying is to add subinterface for vlan 1 to Fa0/1

interface fastethernet 0/0.1
encapsulation dot1q 1 native

Trunk needed native VLAN for trunk to work properly.
