i feel there is some issue with the configuration or the ios image needs to be changed to the stable version. because i feel that ios image i had put is he amsterdam one...i m thinking to downgrade to 16.9

[amikat]

Hi,

Thanks for the response. While I have checked the bug tool and have not identified any bug which could be related I think it is a good idea to downgrade. As I have already mentioned my lab setup using your router configuration works just fine but at the moment I have not your router model available so I am using a different box with another IOS release.

I would be interested to see the "debug cry isakmp" and "debug cry ipsec" outputs taken when VPN connection is attempted - please beware these are rather chatty.

Best regards,

Antonin

[kev_mas01]

i have attached the debug file please check the txt file..

[kev_mas01]

i have attached the debug file please check

[kev_mas01]

i m still getting same error of port is closed.. router config is attached this is latest.. Please check

[kev_mas01]

i put the config what u have guided me still no luck port is closed it says.. i m attaching the new debug info

[amikat]

Hi,

Thanks for the information supplied. The indication of your issue is almost at the end of the debug:

"%FMANRP_ESS-4-FULLVAI: Session creation failed due to Full Virtual-Access Interfaces not being supported. ......"

There are couple of bugs found relating this message but none fits exactly to your box. Before we go any further can you please post your current router configuration as I understand you have changed it several times since the original one. Please BEWARE that up to now you have published quite a lot of the sensitive information as for your configuration so PLEASE change at least your authentication data (ie. username/password) with the IMMEDIATE EFFECT and do not publish these any more.

Thanks & Regards,

Antonin

[kev_mas01]

i have attached my latest router config.. Please check still i get that the port is closed i dont understand it at all...

[amikat]

Hi,

Thanks for the reply and the information supplied. Will you please adjust your current router configuration as per beneath:

1) Please change your pre-shared key (cisco) to another secret (both sides) and do NOT publish this any more.

2) Please add the command "reverse-route" under the "crypto dynamic-map ipnet-map 10".

3) Please add the command "ip nat inside" under the "interface Virtual-Template2".

4) Please add the command "permit ip 172.10.1.0 0.0.0.255 any" under the "ip access-list extended natlist".

5) Please check your WAN miniport L2TP configuration as follows: Properties > Networking tab > double click on IPv4 > click Advanced  > check Use default gateway on remote network (default setting).

If still experiencing VPN error 619 can you please post the debug output (debug cry isakmp, debug cry ipsec, debug ppp negot) taken when VPN is initiated.

Thanks & Regards,

Antonin 

[kev_mas01]

i have attached the new debug with new config.. please check

[amikat]

Hi,

Thanks for the reply. Can you please try to remove the configuration command "ppp encrypt mppe 40" under the "interface Virtual-Template2" and try again.

Thanks & Regards,

Antonin

[kev_mas01]

hey, thanks when i remove ppp encrypt it now connects great !!!

but i have another small issue is that cannot ping my internal network...Please guide me for that

[amikat]

Hi,

Thanks for the update. Can you please post the "sh ip int br" and "sh ip rou" commands output (router) and also "ipconfig /all" (PC).

Best regards,

Antonin
