to sshuttle
So everything worked perfectly until I updated my OS today to version 12.6.1, after which I found that Internet breaks when sshuttle is connected and realized that DNS is not working.
I tried reinstalling the utility through brew uninstall/install, but it did not help, though it updated all dependencies in the world.
When launched with verbose output I can see something like this:
% sshuttle --dns -r my.centralus.cloudapp.azure.com -e "ssh -F $HOME/azsshconfig -o 'ServerAliveInterval=30'" 10.188.0.0/14 -vvv
Starting sshuttle proxy (version 1.1.1).

c : Keyboard interrupt: exiting.
It can be seen that DNS requests are coming by messages like "DNS request from ('10.142.6.35', 56847)", but I am afraid that the rest of output does not make much sense to me.
Besides DNS issue, the rest seems to work fine. If I add an entry into my /etc/hosts, it solves the problem for that host.
Can anyone please help me to troubleshoot? What diagnostics can I run to pinpoint the issue?
Thank you,
VR

to sshuttle
In regard to the above output, I'll provide some context, for what it worth...
I have to use a VPN called GlobalProtect, which is enforced on my work laptop. I can disable it temporarily but it does not make much sense in this case the SSH server will be unavailable.
The IP assigned to me by this VPN is 10.142.6.35. Normally (when sshuttle is not connected), the DNS server used is 10.142.6.1 (as shown by nslookup).
When sshuttle is connected, the error I am getting from nslookup and dig is:
;; connection timed out; no servers could be reached
I am thinking what change the update of MacOS could bring. One my assumption is that it could somehow affect pfctl or change its configuration. According to this article, each MacOS update (even a minor one) overwrites /etc/pf.conf. Is anything required in that file?
Thank you.
