The Static side will not know which IP to peer with and. The caveat here is that the LAN with the DHCP side ASA needs to be the one that initiates the tunnel by sending interesting traffic. In this window, first, you need to select the interface, then you need to define the destination address with netmask and gateway.
Once you click on Add button, a popup window will appear. Nat (inside) 0 access-list ENCDOM-100-NONAT DHCP IP Peer This script will create a vpn tunnel between one Cisco ASA that has a statically assigned IP and one Cisco ASA that has DHCP assigned IP which will change. Well, now let’s access the Cisco ASA using the ASDM application and navigate to Configuration > Device Setup > Routing > Static Routes and click on Add. Right now its setup as a bridge router and I setup the interface to connect via PPPOE with the credentials provided form ISP. For reasons such as speed limitations and contract status we cant change yet. cable interface with static IP, i have static route to next hop which is the cable modem ip.
Note : The dynamic crypto map should have the highest sequence number within the crypto map to ensure that all other crypto map entries are triggered first. The only difference being is that a dynamic crypto map is configured.Ī dynamic crypto map is a crypto map that does not have all of the parameters defined, these are then later learnt at the point that the IPsec tunnel is formed. On the Peer that has a static IP, the configuration is pretty standard. Note : Unlike other vendors (such as the Juniper SRX), main mode is used for phase 1 negotiations between the dynamic/static based peers (this can be confirmed via the command ‘sh vpn-sessiondb detail l2l’). However as the static based peer will be unaware of the remote peers IP the VPN can only be initated from the dynamic side. To configure a Site to Site VPN between 2 Peers one with a Dynamic IP and the other with a static IP a dynamic crypto map is used.
