My sshuttle stopped working yesterday and am struggling to debug the issue. I route all traffic through a local SSH server on 192.168.1.x, but now none of my networking traffic is being sent to sshuttle. sshuttle is still receiving DNS requests and I see those getting resolved by the local server. What steps do I take to debug the networking issue?

I didn't I'm on os x
I flushed routes multiple times then rebooted and sshuttle started working. Rebooting alone did not resolve things
