![]() "Finally, you will have to exempt the protected traffic from NAT on the loopback" But if you really remove this command, the ping won't work" In that case, Ethernet uses the loopback as a gateway to reach the subnet in question. So, we need to reach the remote protected subnet in order to virtually forward traffic through the Ethernet interface. "Again, the loopback is not a physical interface. Why I said that? Because if you issue debug crypto ipsec, you will notice that the other peer will try to negotiate the tunnel with the 42.x.x.x on ethernet0.156 and it will tells you invalid local address." Without it, the router will think that the endpoint address is the physical interface and the tunnel will never negotiate since the public IP is not defined in the physical interface. The automated sound device loopback test ensures that you will get the optimum. To accomplish this, the following command is important to instruct the router to treat the loopback address as the VPN endpoint. This stimulus signal is played in the enclosure through a sound source. "Because the public IP is defined in the loopback interface, it must be our VPN endpoint. With this app, you can change the output volume of your. Why I said that? Because if I remove the map off one of them, the tunnel won't negotiate" Sometimes you find an app that should be included by default with macOS SoundSource is one of those. Applying the map on both of them is crucial. It's the job of the physical interface, which is the ethernet in my case because it's the actual WAN interface. Since the loopback is a virtual interface, it cannot negotiate the tunnel. "Apply crypto map on both the loopback interface and the Ethernet sub-interface. SOUNDSOURCE VS LOOPBACK FREEPlease feel free to correct me if I am wrong. I am not going to mention other config such as IKE/IPSec proposals, IPSec transform sets, interesting traffic ACL.,etc as you already familiar with. Here is the most important config for a loopback to function as VPN tunnel endpoint along with my humble technical explanation according to my understanding so far. I understand parts of the configuration but other parts I could not understand. To accomplish this, the following command is important to instruct the router to treat the loopback address as the VPN endpoint. However, I still don't understand how it completely works. 'Because the public IP is defined in the loopback interface, it must be our VPN endpoint. After lots of experiments, I could finally get it to work. The documentation of loopback.I've spent two days figuring out how can I use the loopback interface as the tunnel endpoint. Further, loopback is used by many companies to create scalable API manager and web application. Loopback.js is node base framework and will be compatible with the majority of operating systems, such as:īoth javascript and the Node.js frameworks are widely used in the industry, resulting in vast community support on StackOverflow, and the documentation page. Loopback.js - Popular with API ApplicationĪpart from these two, various frameworks exist, you have found which satisfies your requirement. Express.js - Popular with web developmentĢ. Multiple Node.js based Framework already exist and are continuously being improved. Loopback.js is a javascript based framework, build as an enhanced version of Express.js, as it makes it simpler to manage API's, database, tables and models. Does it satisfies the business requirements.The requirements of your application determines, will loopback.js a good, choice for your use.Īsk yourself the following question, before switching to any new framework: ![]()
