当我从家里连接到我的普通 wifi 连接时，它是 192.168，我的 VPN 一切正常，并使用以下命令为 10.0.0.0 地址添加了所需的额外路由：
路由添加-net 10.0.0.0/8 gw 10.100.1.99
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.1 0.0.0.0 UG 303 0 0 wlo1
10.0.0.0 10.100.1.99 255.0.0.0 UG 0 0 0 ppp0
10.100.1.99 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.0.0 0.0.0.0 255.255.255.0 U 303 0 0 wlo1
但是当我连接我的 wifi 热点设备（yourkarma.com）时，它会添加：
169.xxx
地址为 192.168 上方的 wlo1，然后 VPN 就无法正常工作。
当 169 ip 在路由 -n 列表中时，知道如何通过 wifi 热点让 VPN 工作吗？
以下是完整历史记录：

# at this point if I do route add -net 10.0.0.0/8 gw 10.100.1.99

# but to show the problem instead of adding that route, I swtich over to karma wifi
