Description Matt 2001-10-16 14:38:30 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)

Description of problem:
The /etc/rc.d/init.d/iptables depends on /etc/sysconfig/network-
scripts/ifup-post to allow dns traffic through the firewall roules. So if 
you call the iptables init script without rebooting then the ifup-post 
script will not be executed and the dns servers will not be allowed 
through the firewall rules.  aka DNS won't work.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:

1. /etc/rc.d/init.d/iptables restart
2. Try to resolve any network names
	

Actual Results:  DNS names cannot be resolved and dig says server does not 
respond.

Expected Results:  DNS names should be resolved.

ifup-post doesn't touch iptables at all. That code is there mainly for lokkit
and the like; we assume that custom firewalls would be written to allow DNS.
