我在 Ubuntu 20.04 上，并且已启用 UFW 作为终止开关以与我的 wireguard vpn 配合使用。我当前的规则运行正常，只是我的 ubuntu 主机和 debian 10.5 virtualbox 客户机之间的流量被阻止了。
我如何解除对主机/访客流量的阻拦？
我当前的 UFW 规则是：
[ 1] 22/tcp ALLOW IN Anywhere
[ 2] Anywhere ALLOW OUT Anywhere on wg-client1 (out)
[ 3] 80/tcp ALLOW IN Anywhere
[ 4] 443/tcp ALLOW IN Anywhere
[ 5] Anywhere on wg-client1 ALLOW IN Anywhere
[ 6] 94.121.83.88 ALLOW OUT Anywhere (out)
[ 7] 21/tcp ALLOW IN Anywhere
[ 8] 53 ALLOW OUT Anywhere (out)
[ 9] 9418/tcp ALLOW IN Anywhere
我之前尝试过以下操作但都失败了（例如，当我 ping 客户机 ip192.168.0.84 时，我得到了ping: sendmsg: Operation not permitted）
[10] 22/tcp ALLOW IN 10.10.10.2
[11] 22/tcp ALLOW IN 192.168.0.0/24
[12] Anywhere ALLOW IN 192.168.0.0/24
[13] 192.168.0.0/24 ALLOW IN Anywhere
[14] 192.168.0.0/24 22 ALLOW IN Anywhere
[15] Anywhere ALLOW IN 192.168.0.0/24 22
我还使用伪装将所有流量通过 VPN。我的ifconfig -a输出是：

需要注意的是，我的 debian 客户机有两个网络接口，1 个静态 192.168.0.84 和 1 个动态，以便我可以使用多个 wifi 网络。
# The primary network interface
auto enp0s3
iface enp0s3 inet static
address 192.168.0.84
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
#dynamic gateway for Internet access on random networks
auto enp0s8
iface enp0s8 inet dhcp
谢谢
更新
我终于弄清楚了我的系统日志并注意到了这一点：
[UFW BLOCK] IN= OUT=wlp0s10f2 SRC=192.168.0.255 DST=192.168.0.84 ....
因此，我当然检查了 vbox 管理器，对于我的桥接连接适配器，我只有 2 个选项：wlp0s10f2或enp3s0（以太网）
尽管ifocnfig -a显示wg-client1为网络接口，但我在 VirtualBox 中没有wg-client1可用的接口。
我尝试了不同的规则来允许 22/tcp wlp0s10f2，wg-client1但是没有成功。
有小费吗？
答案1
有点尴尬，但在开始赏金后不到 5 分钟，我就根据有根据的猜测解决了这个问题：
sudo ufw allow out on wlp0s10f2 from any to 192.168.0.84
现在我的全新安装完美运行。我的错误是使用 vpn ip 作为出站地址。将其更改为 vbox 机器的 ip 地址。让我回到正轨。
