Changin peer IP in on VPN tunnel config

Hi Syed,

On the ASA and IOS Routers this change is made under the crypto map settings as following:

crypto map mymap 10

no set peer old_ip_address

set peer new_ip_address

However there are some specific commands:

ASA 8.3 and earlier:

tunnel-group new_IP_address type ipsec-l2l

tunnel-group new_IP_address ipsec-attributes

     pre-shared-key xxxxx

ASA 8.4 and above:

tunnel-group new_IP_address type ipsec-l2l

tunnel-group new_IP_address ipsec-attributes

    ikev1 pre-shared-key xxxxx

On IOS you need to update the pre-shared-key as well:

crypto isakmp key 0 xxxxx address new_IP_address no-xauth

HTH.

Portu.
