You can use the configuration template provided below and fill in the missing information.This document describes how to configure a site-to-site (LAN-to-LAN) IPSec Internet Key Exchange Version 1 (IKEv1) tunnel via the CLI between a Cisco Adaptive Security Appliance (ASA) and a router that runs Cisco IOS ® software.Site to Site VPN Tunnel Between ASA and Router. After you have created your site-to-site VPN connection in Microsoft Azure, you need to configure your Cisco firewall to recognize the connection and let traffic into your MacStadium private cloud. Azure VPN Config for Cisco ASA/ASAv.Neither Cisco IOS VPN routers nor the VPN 3000 Series Concentrators support the iPhone VPN capabilities. The router needs to have an IOS that supports VPN’s.Cisco specifies that iPhone is compatible only with Cisco ASA 5500 Security Appliances and PIX Firewalls. The firewall on the left is a Cisco ASA and device on the right is a Cisco Router.All of the devices used in this document started with a cleared (default) configuration. Cisco 1941 Series Integrated Services Router (ISR) that runs Cisco IOS software Version 15.4(3)M2The information in this document was created from the devices in a specific lab environment. Cisco 5512-X Series ASA that runs software Version 9.4(1) Recently I had to create a VPN tunnel from a Cisco ASA running 9.The information in this document is based on these software and hardware versions: Cisco recommends that you have knowledge of these topics:Verify that the security group rules assigned to the EC2 instances in your VPC allow. It would be extremely helpful for a large number of users if.
Build Vpn Tunnel Group Cisco Asa How To Configure A![]() Object-group network local-networkAccess-list asa-router-vpn extended permit ip object-group local-networkNote: An ACL for VPN traffic uses the source and destination IP addresses after Network Address Translation (NAT).Note: An ACL for VPN traffic must be mirrored on both of the VPN peers.Note: If there is a need to add a new subnet to the protected traffic, simply add a subnet/host to the respective object-group and complete a mirror change on the remote VPN peer.Note: The configuration that is described in this section is optional.Typically, there should be no NAT performed on the VPN traffic. It protects the outbound packets that match a permit Application Control Engine (ACE) and ensures that the inbound packets that match a permit ACE have protection. In order to configure the IKEv1 preshared key, enter the tunnel-group ipsec-attributes configuration mode: tunnel-group 172.17.1.1 type ipsec-l2lConfigure the ACL for the VPN Traffic of InterestThe ASA uses Access Control Lists (ACLs) in order to differentiate the traffic that should be protected with IPSec encryption from the traffic that does not require protection. In order to enable IKEv1, enter the crypto ikev1 enable command in global configuration mode: crypto ikev1 enable outsideConfigure the Tunnel Group (LAN-to-LAN Connection Profile)For a LAN-to-LAN tunnel, the connection profile type is ipsec-l2l. Amiga mac ii emulatorHere is an example: interface GigabitEthernet0/0Ensure that there is connectivity to both the internal and external networks, and especially to the remote peer that will be used in order to establish a site-to-site VPN tunnel. An access list in order to identify the packets that the IPSec connection permits and protectsHere is an example: crypto map outside_map 10 match address asa-router-vpnCrypto map outside_map 10 set peer 172.17.1.1Crypto map outside_map 10 set ikev1 transform-set ESP-AES-SHAYou can then apply the crypto map to the interface: crypto map outside_map interface outsideHere is the final configuration on the ASA: interface GigabitEthernet0/0Nat (inside,outside) source static local-network local-network destinationStatic remote-network remote-network no-proxy-arp route-lookupCrypto ipsec ikev1 transform-set ESP-AES-SHA esp-aes esp-sha-hmacCrypto map outside_map 10 match address asa-router-vpnIf the IOS router interfaces are not yet configured, then at least the LAN and WAN interfaces should be configured. The ASA then applies the matched transform set or proposal in order to create an SA that protects data flows in the access list for that crypto map.In order to configure the IKEv1 transform set, enter the crypto ipsec ikev1 transform-set command: crypto ipsec ikev1 transform-set ESP-AES-SHA esp-aes esp-sha-hmacConfigure a Crypto Map and Apply it to an InterfaceA crypto map defines an IPSec policy to be negotiated in the IPSec SA and includes: During IPSec Security Association (SA) negotiations, the peers must identify a transform set or proposal that is the same for both of the peers. Nat (inside,outside) source static local-network local-network destination staticRemote-network remote-network no-proxy-arp route-lookupAn IKEv1 transform set is a combination of security protocols and algorithms that define the way that the ASA protects data. The identity NAT rule simply translates an address to the same address. If the NAT overload is used, then a route-map should be used in order to exempt the VPN traffic of interest from translation. Here is an example: access-list 110 remark Interesting traffic access-listAccess-list 110 permit ip 10.20.10.0 0.0.0.255 10.10.10.0 0.0.0.255Note: An ACL for VPN traffic uses the source and destination IP addresses after NAT.Typically, there should be no NAT performed on the VPN traffic. When the IKE negotiation begins, it attempts to find a common policy that is configured on both of the peers, and it starts with the highest priority policies that are specified on the remote peer.In order to configure a preshared authentication key, enter the crypto isakmp key command in global configuration mode: crypto isakmp key cisco123 address 172.16.1.1Configure an ACL for VPN Traffic of InterestUse the extended or named access list in order to specify the traffic that should be protected by encryption. ![]()
