[BlueOnyx:23571] Re: 5209R - iptables issue

[Brent Epp]

Hi Colin,

Next time this happens, before flushing the tables, run `iptables -L -n` 
and look for any peculiar rules.  Check particularly the fail2ban chains.

Perhaps make daily-run script to dump a list of the iptables rules to 
file so you can compare the rules from before and after the connection 
starts failing.
