제안된 명령(Hauke ​​Laging 제공)을 PostUp스크립트 로 실행할 때 wg0.conf사용자가 wg0 인터페이스를 통해 트래픽을 전송하지만 여전히 인터넷에 액세스할 수 없는 이유는 무엇입니까?

#!/bin/sh
# up.sh

iptables -t mangle -nvL OUTPUT | grep -q 0x2a ||
    iptables -t mangle -A OUTPUT -m owner --uid-owner test -j MARK --set-mark 42

grep -q '^42  vpn$' /etc/iproute2/rt_tables ||
    echo '42  vpn' >>/etc/iproute2/rt_tables

ip route show table vpn | grep -q default ||
    ip route add default via 10.66.95.98 dev wg0 table vpn

ip rule | grep -q 0x2a ||
    ip rule add fwmark 42 lookup vpn prio 42

현재 구성 wg0.conf은 다음과 같습니다.
