vpnc: quick mode response rejected: (ISAKMP_N_INVALID_PAYLOAD_TYPE)(1)

So I've had vpnc up and working to connect to my company's VPN
concentrator, then all of the sudden i stopped working..Apparently they
must have made a change on the Cisco concentrator...Does anyone know if
there is a workaround for this problem, or if there's another Cisco
compatible client available for linux?

vpnc: quick mode response rejected: (ISAKMP_N_INVALID_PAYLOAD_TYPE)(1)

this means the concentrator did not like what we had to offer.

Possible reasons are:

* concentrator configured to require a firewall

this locks out even Cisco clients on any platform expect windows

which is an obvious security improvment. There is no workaround (yet).

* concentrator configured to require IP compression

this is not yet supported by vpnc.

Note: the Cisco Concentrator Documentation recommends against using

compression, expect on low-bandwith (read: ISDN) links, because it

uses much CPU-resources on the concentrator

OS: FC12
vpnc version: 0:0.5.3-4.fc12

I just switched to openconnect because my company changed to Cicso
Anyconnect.
