Workaround is to run the following

echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf
sysctl -w net.ipv4.ip_forward=1

Verified with version atomic-openshift-utils-3.2.47-1.git.0.34a924d, the "net.ipv4.ip_forward" setting is persisted on nodes.

[root@node ~]# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

[root@node ~]# grep net.ipv4.ip_forward /etc/sysctl.conf
net.ipv4.ip_forward=1
