Ipsecuritas sonicwall4/6/2023 ![]() ![]() 4.3 Primary Gateway: Put the IP address of the remote site.4.2 Authentication Method: Use the authentication method.4.1 Policy Type: Select the policy type “ Tunnel Interface” or “ Site-to-Site“.Here we will need to fill in the general details. Make sure the Global VPN Settings is “ Enabled” and then click “ ADD” to configure VPN settings. Both locations are shown below in the image. VPN settings are at different positions for the “ Contemporary” and “ Classic” modes of GUI. ConfigurationĪfter login, navigate to the VPN settings. In this article, we will discuss how to configure a site-to-site VPN tunnel on SonicWall Network Adaptive Appliances. SonicWall NSA supports two types of VPN tunnels. Model: NSA 6600, NSA 3600, NSA 250M, NSA 2400 etcĭescription: This article is to discuss and show a stepwise method to configure a Site-to-Site IPSec VPN tunnel on SonicWall Network Adaptive Appliances. I am using a sonicwall with under <4.0 firmware and snow leopard.Make: SonicWall Network Adaptive Appliances I noticed on the sonicwall that when I had a tunnel before opening the firewall I would have an address like 10.10.10.2(publicwanIP) - Once I configured the firewall, I only had the 10.10.10.2 address under users. This essentially bypasses the firewall on the outbound side for port 4500. So I set up a firewall rule to allow IPSEC/NAT-T UDP outbound (port 4500). Some people report that some routers allow this and others don't allow NAT-T to work. If NAT-T was enabled then no tunnel would come up. If I had NAT-T off the tunnel comes up but no connectivity to remote resources. You have to enable the manual configuration of the IP address in the sonicwall as the article states. #1 I don't think ipsecuritas does DHCP over VPN. There are a couple of things that make this a problem. Please contact me if you need help with your connection. Also, be wary of mapping multiple networks behind the Sonicwall, each has to build its own contract. Always have your log file open when trying to debug these connections. Otherwise you will get "NO PROPOSAL WAS CHOSEN" when trying to negotiate phase 1. The reason for this was that IPSecuritas just does PFS without an option to turn it off or on, so you must turn it on, on the Sonicwall. The key for me was Perfect Forward Secrecy was NOT enabled but it should have been! So ENABLE perfect forward secrecy. Name Server Addresses: probably your domain controller ip address Store Password: checked if you would like the password to be storedĭNS: check "enable domain specific DNS servers" just fill in the "Unique Firewall Identifier" from the Sonicwall VPN section Remote Mode: Network (Internal LAN network of the Sonicwall, such as 10.0.1.0 CIDR/Mask 24) ![]() Remote IPSec Device: IP or host name of Sonicwall (must be reachable from Internet)Įndpoint Mode: Host (IP Address left blank) Use Default Key for Simple Client Provisioning is Selected Personal Firewall on Client Machine is Not Required Set Default Route as this Gateway is Not SelectedĪpply VPN Access Control List is Not Selected ![]() Virtual Adapter Settings: DHCP Lease or Manual Configuration Policy Options : PFS: on Xauth: on Netbios: on Multicast: offĬache XAUTH User Name and Password on Client: Never ![]() IPsec Proposal : DH Group 2 Encrypt/Auth - ESP: 3DES/HMAC SHA1 IKE Proposal : DH Group 2 Encrypt/Auth - 3DES/SHA1 Sonicwall side config (straight out of the tech support report)Īuthentication Method : IKE with Preshared secret I always had some difficulty getting the free IPsecuritas connected so I am sure others had problems too. ![]()
