[PATCH 3/4] BUG11559: firewall-lib

[Alexander Marx <alexander.marx@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1730 bytes --]

When creating firewallrules or using firewall groups,
it should be possible to select a single IpSec subnet if there is more than one.

This patch has neccessary changes for the firewall-lib. While the network name of the IpSec changes
on save (subnet is added to name) we need to split the name or normalise the field before using it.
