OpenConnect VPN Push all traffic

I have setup an OpenConnect VPN using LUCI, it seems that the default behavior of the VPN is to have a split network, What I want is to have all traffic from the Remote devices to traverse the VPN, but I am at a loss. I have read the OpenConnect Documentation and I'm having some issues in getting it to work. I have added a "Default" route, but The configuration doesn't seem to be functioning like I want it to.

It works like that when testing OpenConnect client and server on OpenWrt, so your problem is likely on the server side.

The OpenWRT router is acting as the server, I VPN into the network from my phone and laptop while I’m away. I’m wanting all traffic on these devices to go over the vpn.
