On openSUSE 13.1, I investigated sshuttle from the security repository and
noticed that is doesn't work while SuSEfirewall2 is running with default
settings.
"Doesn't work" means: When sshuttle is started all network-traffic is blocked
(can't ping, can't do nslookup) instead of tunneled. However, there is no sign
in /var/log/messages or /var/log/firewall that SuSEfirewall2 would have blocked
something.

I used the following command line to start sshuttle as root
 sshuttle --dns -r user@ssh-tunnel-host 0.0.0.0/0 -v

When doing a "rcSuSEfirwall2 stop" prior starting sshuttle, tunneling works
fine.

Now I wonder: Can the default setting of SuSEfirewall2 can be modified in order
to let sshuttle do it's work?
