* create a own target

do whatever you want to do
-------------------------
that below is something similar to not break existing connections by
reboot the gateway by disable nf_conntrack_tcp_loose at boot but do it
90 seconds later, in that cae no own target needed
[root@firewall:~]$ cat /etc/systemd/system/network-up-post.service
[Unit]
Description=Network Invalid-Detection
After=network-up.service
Requires=network-online.target
[Service]
Type=oneshot
RemainAfterExit=yes
TimeoutStartSec=90
ExecStart=/usr/bin/sleep 30
ExecStart=/usr/sbin/sysctl -q -e -w net.netfilter.nf_conntrack_tcp_loose=0
[Install]
WantedBy=multi-user.target
