nftables DNAT转发失效求助：迁移自iptables后无法访问后端容器

Hey everyone,

I'm currently migrating my firewall configuration from iptables to nftables. My systemd containers are running behind a NAT network, and I needed to set up port forwarding for ports like 80 and 443 to direct traffic to these backend containers.

When I executed the corresponding nftables commands, there were no error messages returned—everything appeared to run without issues. But despite that, I couldn't access the web servers hosted in the containers through the forwarded ports at all.

Update: This problem has been fully resolved thanks to the helpful comments from the community! I really appreciate everyone's assistance.
