Description Kevin R. Page 2007-04-18 10:11:35 EDT
Description of problem:
There's no option in the firewall configuration to allow further layer 3
protocols. e.g. to receive multicast streams (e.g. the BBC test streams) a PC
not only needs to allow the UDP ports for the stream itself, but to join and
communicate with the multicast group using IGMP. With incoming IGMP blocked, the
stream will cease as multicast group membership isn't maintained.

Using iptables, I might use:

iptables -I RH-Firewall-1-INPUT --protocol igmp --jump ACCEPT

It would therefore be useful to have an option to enable other network layer
protocols in system-config-securitylevel, or alternatively perhaps an way to add
options in /etc/sysconfig/

Version-Release number of selected component (if applicable):
Comment 1 Thomas Woerner 2007-09-24 10:13:31 EDT
Assigning to system-config-firewall in devel.
Comment 2 Jon Stanley 2008-04-23 16:28:49 EDT
Adding FutureFeature keyword to RFE's.
Comment 3 Thomas Woerner 2013-11-06 14:32:31 EST
Closing because there will not be big changes to system-config-firewall anymore.
