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?
