Hope this link helps..


But before configuring do make sure that you have the required ios code installed in your respective boxes to configure vpn.

You can make use of feature navigator tool to find out the required as well as the compatible ios code which can fit in with your current hardware config..

I have several L2L VPNs for remote offices. Are you talking about a Remote-Access VPN or Site 2 Site. Below is an example of a L2L (site2site) vpn configuration from an ASA i have, minus the real IP's. And you must include an access-list for whatever you want to allow access to, as well as NAT depending on your scenario.

isakmp enable outside

isakmp key softtekpeople address %public.ip.they.connect.to% netmask

isakmp identity address

isakmp nat-traversal 20

isakmp policy 10 authentication pre-share

isakmp policy 10 encryption des

isakmp policy 10 hash sha

isakmp policy 10 group 5

isakmp policy 10 li

crypto map %map.name% 40 match address %access-list.name.for.cryptomap%

crypto map %map.name% 40 set peer %public.ip.for.your.client%

crypto map %map.name% 40 set transform-set ESP-DES-SHAfetime 86400

crypto map %map.name% 40 set security-association lifetime seconds 3600
