Synology How to Connect to Your RT6600ax via HTTPS

Did you know that you can use an SSL certificate and connect to your Synology RT6600ax router via HTTPS? In today’s article I will show you how to connect to your Synology router in HTTPS and see your browser address bar with the green padlock. The procedure that allows you to connect to your SRM Synology RT6600ax router over a secure SSL connection is similar to the one for the NAS.

  • STEP 8

With the settings described above you can connect to your Synology router from your home or from your local network in HTTPS using your own SSL certificate. You will not be able to access your router if you connect from an external IP such as from the Wi-Fi of a pizza place or from your friend’s house. To allow you to connect to your RT6600ax router in HTTPS / SSL when you are not at home, you must activate the following option described below. Note: I don’t keep this option below active; I only use it if I have to go away from home for 2 or 3 days, just in case I need to have full access to my RT6600ax router.

Log in to your RT6600ax router. Go to Control Panel / System / SRM Settings / Check “Allow external access to SRM” then click OK. Follow the instructions in the image below.

The SSL certificate released for free by Let’s Encrypt has a lifespan of 3 months starting from the day of its activation. To renew the SSL certificate of your custom DDNS you will need to follow the steps described below.

Log in to your RT6600ax router. Go to Control Panel / Services / Certificate. On the Server certificate area click Renew Certificate. Your certificate will update within a few seconds. Follow the instructions in the image below.

Note: I recommend you change your SRM Default port numbers. Use different ports, other than the default HTTP 8000 and HTTPS 8001 ports you can see in the screenshot at STEP 8.
