X440 IPForwarding Not Working as Expected

X440 IPForwarding Not Working as Expected

Justin_Brooks

I currently have and X440 at one of my sites that I am creating a new VLAN to add in some additional IP's. I successfully did this at another site and it worked like a charm, but this one seems to not be cooperating. I have both rip and ipforwarding enabled on the Default and the new VLAN. The Default VLAN can ping the IP of the new VLAN and the new VLAN can ping the IP of the Default VLAN, but the new VLAN can't ping any devices on the old VLAN and the old VLAN can't ping any devices on the new VLAN.

I find it odd that the same config worked at another site, but doesn't on this one. The only difference from one site to another is the IP addresses used.

If it was it wouldn't let you enable ipforwarding due to the license.

It's an x440-24x, where the one that I have configured exactly the same is an x440-48p. I am fairly certain that it wasn't on the list of ones that wouldn't do routing.

Hello Justin,

Based on the configuration it looks like you are adding a PC to port 3 in the wifi VLAN and trying to ping from that device to other devices in the default VLAN?

If this is true is the device receiving a DHCP address from a server? if so, what is the default gateway. In this setup the default gateway would need to be the ip address of the switch it is connected to (10.1.22.210) in order to reach outside the network. Can the device ping this IP?
