SSH reverse tunnel not working for webserver

I have a webapp running on a Raspberry Pi, which is behind a NAT, and I'm trying to make a tunnel to the company's server so that I can access it from the web. Right now I've been able to establish a tunnel using ssh -fN -R 192.168.0.28:54321:localhost:443 [email protected] (both the server and the RPi are in the same LAN at the time), and doing curl -k https://192.168.0.28:54321 returns the contents of the webpage hosted in the RPi, but only if I do it from the server. I have set GatewayPorts yes and AllowTcpForwarding yes (which anyway is the default).

It was the firewall on the server blocking the port. ¬¬

To open said port, the command is sudo iptables -I INPUT -p tcp --dport 54321 -j ACCEPT, which says that any connection comming to the TCP port 54321 must be accepted.
