How to set-up SSH/HTTP access from outside (WAN)?

Hi. I would like to be able to perform SSH or HTTP connections to a specific computer at home. I understand the IP is not static and may change over time (this is for occasional connections and not for commercial/permanent purpose).
I have enabled port forwarding on the modem admin page for both of those ports. I have also disabled the firewall (a rule that will be hardened later on once I get a grasp on the solution). I can further ping the modem from an external IP.
From within the LAN, SSH and HTTP connections to the WAN IP are successful, which means that the port forwarding works somehow. However, I am not able to do the same from an external server.
Can someone help in this regard?
Best,
Pier-André
