VLAN Routing and Config
I have read through many forums and configurations and am missing something, I hope you guys can tell me what it is. I have a single network 192.168.16.0 VLAN 3. The network has grown and is now subbed out to another company, so vlans were mentioned. I want to create a vlan to separate that company from our network/computers, however they will be sharing our DHCP server and Term Server along with internet connection. I see I have to have a management vlan so I have assigned it to 192.168.11.0 VLAN 1 and the new company 192.168.10.0 VLAN 2. I have not been able to get inter vlan routing to work properly.

You mentioned that I had extra stuff in my config, and at this point I'm not opposed to trashing it and starting over. What's your thought on that?

Currently I am just trying to get this running in a stand alone operation with no other switches.
Computers on VLAN 3 are able to get DHCP because the server that is running DHCP is also on this VLAN. Computers on VLAN 2 are unable to ping to VLAN 3 even with a static IP Address set.
192.168.16.254 is our gateway, I have also given the gw multiple IP addresses, one for each vlan subnet but have been unsuccessful with pinging other than VLAN 3.
I am currently updating firmware to latest version.

With static IP on VLAN 2 I can ping and get a response from the switch, I can also ping the switch IP assigned to VLAN 3 however that is the extent of the ping. I cannot ping any device on VLAN 3 other than the switch.

Ok here is my current running config. With this config I cannot ping or see switch from VLAN 2 or 3 with a static IP assigned to the client computer.

Ok i have removed the vlan associations and have the computers configured as you mentioned, with the GW as the switch. When I do show ip route it comes back empty with the legend for Route Codes.

I am able to see my switch when plugged into the correct VLAN, but unable to ping the other VLANS.
192.168.10.1 can ping 192.168.10.210
192.168.16.1 can ping 192.168.16.210

I guess I have been a little impatient with running commands. Now when running the show ip route I get
192.168.10.0/24 directly connected vlan 2
192.168.16.0/24 directly connected vlan 3
I can also ping from 192.168.16.1 to 192.168.10.1 but cannot the other way around

The vlan 3 State is Up, the laptop went to sleep when I ran the Show cmd. But I have verified that pings are still acting the same and reran the cmd and now have Up Up
