I use OpenConnect VPN for this pareticular task.

and yes I know the vpn changes it, then should put it back when one
disconnects.

problem is, where is it getting the old address from? It isn't in 
the resolv.conf before the vpn is started, and it is not in the NM
setups, anywhere, and it isn't in any of the files in /etc/sysconfig/network*,
so where is it coming from? And that particular system is NOT using
DHCP. Beats me!
