Description Jakub Jelen 2014-07-29 12:43:52 UTC

Description of problem:
In current version of firewalld, it is possible and valid to write

# firewall-cmd --add-port=120-100

which causes in iptables in

-A IN_public_allow -p tcp -m tcp --dport 100:120 ...

Swapping port ranges was removed from iptables back in 2002 (see to bz1124382) and I think that it will lead only to mistakes.

Some says that this is useful feature, but I don't see any gain in this feature.

Another option was to allow this, but to trigger some Warning message to inform user that this is maybe not what he wanted.
