hi

so far I have always been able to reload iptables rules on a machine I'm connected via ssh to, and that was done without current ssh connection being interrupted.

as I have migrated from kernel 4.4.112 to 4.14.14, each time I reload iptables, ssh connection is dropped.

where should I search for the change in this behavior?

thank you.

I'd start by ensuring there are no rules that may affect your ssh connection...

Does simply flushing the tables cause problems?

What are your exact steps resulting in reload?
Do you have some intermediate, failsafe stage there?

Also, "connection drops" means "it resets and I reconnect" or "it resets and I can't reconnect", or maybe something else?
