Nagios Support Forum

Read through the posts on DHCPNOFFERS received, and did what is in this post:

I did a iptables stop/start after applying the changes and lost the changes to the iptables. Of course reapplying the change cleared up the issue.

So the question is, will this be persistent if we restart the nagios server? If not, how can I make it persistent? I'm not a full network guy so I'm not sure of the commands to do so.

Those tables changes should stick, at least with the command Scott showed. I wouldn't think that restarting would drop the alterations.

Restarted the server this morning for something else and it looks like those changes don't persist. Had to re-run the command.

You will need to save the itables config: http://www.centos.org/docs/5/html/5.1/D ... aving.html

Thanks, that did it. Since I don't adjust the networking features often, i'm never sure how to make them persistent.

np. Have a great week!
