Select Enable Keep Alive to use heartbeat messages between peers on this VPN tunnel. If one end of the tunnel fails, using Keepalives will allow for the automatic renegotiation of the tunnel once both sides become available again without having to wait for the proposed Life Time to expire.

Hi I've got 2 cisco asa on Active/standby configuration. and Im trying to establish a site-to-site VPN with sonicwall in our remote office. Ive tried creating a VPN using the ASDM but it doesnt work. the public IP on the outside interface on ASA1 is 56.xx.xxx.21 ASA2 is 56.xx.xxx.22 Using the above network diagram, the scripts below can be applied to both ASA’s to build a site to site VPN tunnel. The firewall on the left is a Cisco ASA and device on the right is a Cisco Router. The router needs to have an IOS that supports VPN’s. You can test this by typing ‘crypto ?’ and see if it has the commands available to I've gotten as far as getting the tunnel up, and sites behind the Cisco 1841 can ping sites behind the Sonicwall, but sites behind the Sonicwall get a reply from the Cisco's WAN IP saying Recently I had to create a VPN tunnel from a Cisco ASA running 9.2.2 code to an Amazon AWS instance. I was able to build the tunnel and get it established but it would only work if traffic originated from the ASA side towards AWS. If AWS tried to initiated the tunnel it would not come up. Specifically I saw these errors in the logs: From the SonicWALL side, you will however see the familiar green circle indicating the VPN is live and you will be able to pass traffic over the tunnel. If you want to see the status from the USG, you can log into the CLI and type the command “show vpn ipsec status” which will indicate if the IPsec tunnel is active. If you have one or more branch offices, IPsec VPN creates an encrypted mesh between them, enabling them to function as a single virtual network. IPsec even interoperates with other firewalls (tested with Cisco, Sophos and SonicWALL devices). Securely extend your network resources to mobile, remote and branch office users today with IPsec VPN. IKE PHASE #2- VPN Tunnel is established during this phase and the traffic between VPN Peers is encrypted according to the security parameters of this phase. ! I created Transform-set, by which the traffic will be encrypted and hashed between VPN peers. ASA(config)# crypto ipsec transform-set ts esp-3des esp-md5-hmac

Paul Kroon above mentioned a couple of workarounds. The other is to do double NAT: Source NAT the office to 10.1.0.0 and DC to 10.2.0.0. You must have unique (non NAT'd and routable) for the two ends of the VPN tunneL, usually the public addresses. Looks like the SonicWall has some NAT policies that could work with the Cisco device to

Jan 05, 2007 · This document demonstrates how to configure an IPsec tunnel with pre-shared keys to communicate between two private networks using both aggressive and main modes. In this example, the communicating networks are the 192.168.1.x private network inside the Cisco Security Appliance (PIX/ASA) and the 172.22.1.x private network inside the SonicwallTM TZ170 Firewall.

Third-party VPN Configuration. Setting up a VPN tunnel between MXes in different orgs requires the use of the third-party VPN section of the MX Dashboard. This can be found under Security & SD-WAN > Configure > Site-to-site VPN > Non-Meraki VPN peers. In both organizations, click the "Add a peer" link. I love to work on CLI (command line) and cisco Firewall is my favorite and have successfully created vpn tunnels including Cisco ASA, SonicWALL, Cyberoam, Checkpoint, Palo-Alto and lots more. As a network engineer, it doesn’t matter what vpn device you are using at each end of the vpn site.
