VPNC cisco + erro de resposta rápida do modo rejeitado

1

Eu instalei um vpnc na minha versão 6.3 da máquina de chapéu vermelho do Linux

A maioria dos casos vpnc funcionam bem (conectando-se a clientes de gateway pelo vpnc)

Mas contra alguns clientes particulares (gateways da Cisco), imediatamente após ativar o vpnc, recebo as seguintes mensagens:

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

Neste caso, o Vpnc não pôde ser conectado

Por favor, informe qual é o problema aqui? ,

 [root@TEST-LINUX-MACHINE /var/tmp]# vpnc

 **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

Eu também tento fazer o seguinte

  Add the line "NAT Traversal Mode cisco-udp" in /etc/vpnc.conf

Ou

   Add the line "Local Port 10000" in /etc/vpnc.conf

Mas eles dosent ajudam e eu ainda recebo as mensagens ruins (chuld não ser conectado pelo vpnc)

Por favor, conselhos onde está o problema?
