[SL7.1] iptables-services and iptables packages not sync?

[Dirk Hoffmann]

Dear co-users,

Can anyone reproduce the following error on SL7.1?

$ sudo yum install iptables-services
[...]
Downloading packages:
iptables-services-1.4.21-16.el7.x86_64.rpm                 |  49 kB   00:00
Running transaction check
ERROR with transaction check vs depsolve:

[...]

$ rpm -q iptables
iptables-1.4.21-13.el7.x86_64

$ sudo yum install iptables-services-1.4.21-13
No package iptables-services-1.4.21-13 available.

Any hint what to do?
