VPN between an 837 and a VPN 3030

I am trying to establish a VPN between the above devices. I am unable to get past phase 1.

Here is the error I get on the 837 (running v12.3(2)T1):

atts are acceptable. Next payload is 0

processing vendor id payload

vendor ID seems Unity/DPD but major 123 mismatch

vendor ID is NAT-T v2

processing vendor id payload

vendor ID seems Unity/DPD but major 194 mismatch

This is the only only error I receive on the 3030 (v4.0.1.A):

Group [VPNC_Base_Group]

Sending IKE Delete With Reason message: No Reason Provided

Can some one offer some assistance?

The 837 is a PPPoE connection and is using NAT-T (udp 4500)

Thanks,

RJ

Re: VPN between an 837 and a VPN 3030

There are a couple of things that you could look into. Ensure that the devices are not using an older version of IOS that doesn't support NAT-T. Check to see if the devices using NAT-t are actually behind a NATing device.Check if you have not blocked 4500 udp.
