Disable access on port 3000

[hywax]

After domain binding I would like to disable access directly by ip. How can I do that? I have not found such a point in the documentation

@hywax you can use the firewall and restrict the port 3000

@Siumauricio Then what if the condition when the vps I use does not have a firewall that is managed for free so I have to configure it through ufw. But after I closed the port and only opened for port 22, 80 and 443, ufw does not work with docker so port 3000 is still accessible. The result is that the domain and ip:port are both accessible, not just the domain that should be accessible. do you have any suggestions for me?

I have same question. After check, I consider it maybe docker and ufw are conflcting for port control. It need to change rules of iptables. Do you have better way to control it by using ufw directly? Also for all compose services have same question. @Siumauricio
