SonicWall SSL VPN on Mac: A Comprehensive Guide

As you set up your SonicWall SSL VPN on your Mac, you may encounter issues with pinging local network machines by hostname. In this article, we will explore the reasons behind this problem and provide solutions to help you resolve it.

Pinging a hostname is a common task in networking, but it can be challenging when using a VPN. The issue arises because the VPN server uses its own DNS resolver instead of the default one on your Mac. This means that the hostname resolution process fails, resulting in an inability to ping local network machines by their hostnames.

To better understand this issue, let's first discuss how pinging works. In Windows, the ping command sends four data packets to the target computer specified by IP address or hostname. However, if the IP is correct but cannot be resolved, the ping fails. This is often due to DNS resolution issues.

In your case, you may have noticed that some client PCs can access the network via hostname, while others require an IP address. This inconsistency can cause frustration and make it difficult to troubleshoot.

To resolve this issue, we recommend keeping the registry setting as resolving via hostname. If you are experiencing issues with pinging by hostname, try using the nslookup command instead. This will provide you with the hostname associated with a specific IP address.

Another method to get the hostname from an IP address is to use the nmap command with the '-p' option for port and specify the port number as well as the hostname to be scanned. This can help you identify any issues with DNS resolution or network connectivity.

In addition, make sure that your DNS server is configured correctly and that there are no conflicts with other devices on the network. You may also want to check the shared libraries used by nslookup and ping to ensure they are functioning properly.

By following these steps and troubleshooting tips, you should be able to successfully ping local network machines by hostname using your SonicWall SSL VPN on Mac. Remember to always keep your registry setting as resolving via hostname for optimal performance.
