Configure a Crypto Map and apply it to the outside interface. crypto ipsec ikev1 transform-set AES-HMAC esp-aes-256 esp-sha-hmacĥ. Configure the Transform Set which is a combination of security protocols and algorithms that define the way the VPN peers protect data. Please note that the PSKs should match on both sides. Create a tunnel-group and configure the peer IP address alongside the tunnel pre-shared key (PSK). You can check whether there are any policies by running show run crypto ikev1 command. If you already have a policy then you don't need to create them. Please note that these policies should match on both sides. Create an IKEv1 policy that defines the algorithms/methods to be used for hashing, authentication, DH group, lifetime, and encryption. Enable IKEv1 on the outside interface (if not enabled already)Ģ.So, please make sure not to change or override them.

Please note that if you already have another VPN tunnel then most likely most of the configurations are already done for you.

Same as above except for the object names and the IPs. So, when the user traffic leaves the ASA, the source IP is translated to the IP address of the ASA's outside interface (101.85.10.1) Headquarters interface GigabitEthernet0/1 As you can see above, I have a dynamic PAT configuration for the user subnet. The NAT part is quite important because we will talk about that later. There are two objects, one for the branch user subnet and another one for the HQ webserver subnet. The default route is pointing to the ISP router with a static route. The interface configuration is self-explanatory, ASA has two interfaces, one for the user and another one for the Internet. Cisco ASA non-VPN Configurations Branch Office Branch Office ASA Let's assume the client-pc (10.10.60.10) in the branch office needs to access a web server (192.168.10.10) in the headquarters. Our ultimate goal here is to set up a site-to-site VPN between the Branch Office and the Headquarters.
