In order to allow UDP broadcast with the SUSEfirewall, is it enough to add
e.g. BROADCAST="123,456" to the rules or is there more to add?

I ask, because in my set UDP broadcast may have been dropped, despite
using BROADCAST="123"....
There is no setting with this name for SuSEfirewall2
From /etc/sysconfig/SuSEfirewall2.d/services/TEMPLATE

# space separated list of allowed UDP ports that accept broadcasts
BROADCAST=""

So it's a service.
You'll need to first allow broadcast in general in
/etc/sysconfig/SuSEfirewall2 via FW_ALLOW_FW_BROADCAST_EXT, _INT, _DMZ.

Ah, okay.
Is it okay to make changes in /etc/sysconfig/SuSEfirewall2 ? Doesn´t it
get overwritten with software updates?
Thanks
