I discovered several months ago that none of my users that used Charter internet were unable to access any of my sites. After much poking and prodding, I discovered that the issue was with iptables! Something I had never even heard of until then.
The temporary solution was to disable it using:
But whenever I had to reboot the server, I had to remember to run that command again.
Yesterday, I thought I would try to flush iptables in the hopes of permanently fixing the problem. I ran:
After letting it run for about 10 minutes, I discovered that the server had frozen up. I logged in to my provider's site and issued a soft reboot, but it still didn't come back online. It took about 2 hours of working with a tech there to get it back online, and I'm honestly not sure what s/he did to fix it.
After researching today I now know that /etc/sysconfig/iptables is somehow relevant. Mine is 1.8G in size, which seems quite large, but it was also last updated in March 2016.
Since I run CSF, do I even need iptables?
If not, how do I permanently disable it?
If so, is there a better way to flush it, or to otherwise track down and fix the issue with it blocking Charter?
