build tunnel automatically

Unanswered Question

Dear All,

I have a 831 (HQ) which has a static IP and a Soho91 (BO) which has a

dynamic ip (xDSL).

Is there a way to build up the tunnel automatically from the BO the

the HQ, that the HQ can access data in the BO?

The only way I found is to configure the BO as ezvpn client, but I

didn't get the routing done.

Can somehone help?

Thanks a lot!

Hi Christian,

The best way to do that is using EZVPN in Network Extension Mode, client and server the way you defined above.

If you're willing to run some routing over the tunnel, ie, OSPF/GRE etc., then you can use DMVPN (IPSec/GRE with NHRP).


hope that helps.

Dear Afaq,

thank you for your reply. EZVPN looks like the best

way to solf my problem. Is it posible to do spoke to spoke communication between the ez-vpn clients?

Spoke-to-spoke traffic flows trough the ez-vpn server. IOS and Concentrator support this, while PIX do not allow spoke-to-spoke through the center. It is PIX restriction by design.
