我只需要运行该脚本文件一次吗？

我只需要运行该脚本文件一次吗？之后 docker torproxy 容器将按预期工作，还是我每次重新启动计算机时都需要运行它？

set -euo pipefail # Treat unset variables as an error

# Most of this is from
# https://trac.torproject.org/projects/tor/wiki/doc/TransparentProxy

### set variables
# destinations you don't want routed through Tor
_non_tor="192.168.1.0/24 192.168.0.0/24"

### get the container tor runs in
_tor_container=$(docker ps | awk '/torproxy/')
    if [[ "$_tor_container" == "" ]]; then
    echo 'ERROR: you must start a tor proxy container first, IE:'
    echo '    docker run -d --net host --restart always dperson/torproxy'
    exit 1
fi

### get the UID that tor runs as
_tor_uid=$(docker exec $_tor_container id -u tor)

### Tor's TransPort
_trans_port="9040"
_dns_port="5353"

### flush iptables
iptables -F
iptables -t nat -F

### set iptables *nat to ignore tor user
iptables -t nat -A OUTPUT -m owner --uid-owner $_tor_uid -j RETURN

### redirect all DNS output to tor's DNSPort
iptables -t nat -A OUTPUT -p udp --dport 53 -j REDIRECT --to-ports $_dns_port

### set iptables *filter
iptables -A OUTPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

### allow clearnet access for hosts in $_non_tor
for _clearnet in $_non_tor 127.0.0.0/8; do
   iptables -t nat -A OUTPUT -d $_clearnet -j RETURN
   iptables -A OUTPUT -d $_clearnet -j ACCEPT
done

### redirect all other output to tor's TransPort
iptables -t nat -A OUTPUT -p tcp --syn -j REDIRECT --to-ports $_trans_port

### allow only tor output
iptables -A OUTPUT -m owner --uid-owner $_tor_uid -j ACCEPT
iptables -A OUTPUT -j REJECT

这些iptables设置不会在重新启动后自动保留。因此，除非您的 Linux 发行版具有其他功能，可以在关机时保存当前的 iptables 设置并在重新启动后恢复它们，否则您将需要在每次重新启动计算机时重新运行该脚本。

当然，没有人说你必须这样做手动。

您可能应该考虑将此脚本添加到系统的启动脚本中。详细信息因 Linux 发行版而异。
