Have you tried excluding the server from the range of forwarded hosts? sshuttle -v -r my@server -x server 0/0

[Paul1804]

I tried this command, sshuttle -v -r my@server 0/0 -x 192.168.0.0/24 the output is the same as I indicated above. I will repeat below again. I am at home behind the NAT (wi-fi). I don't understand what to do).

It doesn't look like you are excluding the same address that you are SSH'ing into. If you are SSHing into the fictional IP 300.1.1.1, you would use: sshuttle -v -r [email protected] -x 300.1.1.1 0/0

[Paul1804]

you're messing with something.) it should just work this sshuttle -r [email protected] 0/0 . it's not working for me. This command also doesn't work sshuttle --dns -r [email protected] 0/0 I think there's something wrong with my DNS. How do I check it?
