I’ve been using BetterUptime for the past few months to monitor our different websites and it’s such a great tool. You can read some of the features of this tool in previous posts: WEBSITE MONITORING AND STATUS PAGES and BETTER UPTIME NEW FEATURES – MONITOR YOUR WEBSITE
In this post, I’m going to share with you how I’ve set up my firewall to allow the monitoring of a custom port. Yes, with BetterUptime you can also monitor ports on a server. Generally, different software applications use different TCP/UDP ports to communicate and I used this feature on BetterUptime to monitor ensure the server application is always running.
If you run a small business as we do, then chances are you don’t have a dedicated IT team in your office to take care of all the technical issues. And if you are using a VPS or a Dedicated Server, then you will have to take care of all the operation tasks by yourself – trust me I’ve been there and done that. One of the most important things that you need to take care of on your own is the security of your server. Because if you don’t take steps to set up a good server firewall, you will be vulnerable to attacks that could take down your site or even steal your customers’ information. One of the servers that we monitor is behind a firewall which meant BetterUptime was not able to monitor the ports I needed. In order to securely allow BetterUptime to monitor this port, I needed to add firewall rules on the firewall.
The best way to set up these firewall rules it to allow only specific BetterUptime IP addresses to access the server’s ports. Luckily, BetterUptime provided me with this list and I was able to successfully add these firewall rules to the server. You can find the latest ports here: https://betteruptime.com/ips.txt
For more added security, I’ve added a rule on the Windows Defender Firewall to only allow these remote IP address (BetterUptime monitor servers):
I’ve also only included the port that I’m monitoring, in this case it was the database port 3306:
