Upgrade from 0.76 to 0.78.5 tunnel not working

[Mac McClellan]

I've been using sshuttle for several years now with no issues but I got a new computer, new OS, new version of shuttle and now it does not work.

Old Computer:

OS = Linux Mint 18.3

Shuttle version = 0.76

On Local Network

New Computer:

OS = Linux Mint 20.0

Shuttle version = 0.78.5

On Local Network

My proxy host: MacBook Pro laptop

OS = High Sierra 10.13.6

WiFi is connected to Corp Network on 10.0.0.0/8 network

Wired Ethernet connected to Local Network on 192.168.0.0/24

This works on Old Computer:
sshuttle -r [user]@macbookpro 10.0.0.0/8 149.96.16.216

It does not work on new computer.

149.96.16.216 is an Internet site that is whitelisted to only accept traffic from Corp Network, which is the reason for my tunnel.

I have an entry in /etc/hosts on both old and new computer to resolve the name of host on 149.96.16.216.

How do I troubleshoot this and confirm that the traffic I want to go through the tunnel is actually going through?

Thanks!
