Synology: How to Connect to Your RT2600ac Router via HTTPS / SSL

Synology How to Connect to Your RT2600ac Router via HTTPS

Did you know that you can use an SSL certificate and connect to your Synology RT2600ac router externally or internally via HTTPS? Starting today you can connect to your Synology router via HTTPS and see your browser address bar with the green padlock. The procedure that allows you to connect to your Synology router over a secure SSL connection is similar to the one for the NAS, but some steps are not necessary in the router such as port forwarding which occurs automatically.

With the settings described above you can connect from your home or from your local network in HTTPS using the 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 pizzeria or from your friend’s house. To allow you to connect via HTTPS / SSL to your router when you are not at home, you must activate the following option described below in your RT2600ac. 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 RT2600ac router.

Log into your RT2600ac 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 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 into your RT2600ac 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 8000 and 8001 ports you can see in the screenshot at STEP 7.
Note: The instructions in this article is also perfectly working with RT1900ac and MR2200ac routers.
