因为podman依赖的应该是老版本的iptables, 新版本iptables不兼容， 切换到老版本的方法：

yum install iptables-legacy
sudo update-alternatives --set iptables /usr/sbin/iptables-legacy

update-alternatives这个命令竟然可以在oracle9 centos中使用

ubuntu中切换方法：

root@DESKTOP-6RJPLEM:~# update-alternatives --config iptables
There are 2 choices for the alternative iptables (providing /usr/sbin/iptables).

  Selection    Path                       Priority   Status
------------------------------------------------------------
* 0            /usr/sbin/iptables-nft      20        auto mode
  1            /usr/sbin/iptables-legacy   10        manual mode
  2            /usr/sbin/iptables-nft      20        manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
