Routing question

[DPower]

I have 2 vlans created on a switch (DEFAULT_VLAN & VLAN20), however I am unable to ping any of the devices on VLAN20. I've enable IP routing, I can ping VLAN20's gateway, but no nodes behind it. The odd thing is the nodes are able to grab a DHCP address, so I know they're some what communicating to the DEFAULT_VLAN side.

Any ideas?

hi,
what do you mean with the gateway of vlan 20?
if you have a client in vlan 20 try changing the gateway to the switch ip (10.2.20.253)
and of course you need to let the router (10.2.1.254) know the subnet of vlan 20 and where to find it, something like
ip route 10.2.20.0/24 10.2.1.249
The Switch Config is ok.
