--source-ip not working

[meichengg]

Hi, it seems that --source-ip not working eventhough the IP format is correct, please check again.

I'm connected to a VPN that works with IP routing like this

ifconfig
betterpatch: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>  mtu 1500
        inet6 fe80::b69b:4fe1:a2d4:b68  prefixlen 64  scopeid 0x20<link>
        unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  txqueuelen 500  (UNSPEC)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 8  bytes 384 (384.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

ip route
default via 192.168.88.1 dev eth0 proto dhcp src 192.168.88.119 metric 100
172.16.221.0/24 dev betterpatch

192.168.221.0/24 via 192.168.45.254 dev tun0

This is the command i ran and the error i got
