Suggestion: adds this script to the "pivpn debug" command

IPv4dev=$(ip -f inet address show $(cat /etc/pivpn/wireguard/setupVars.conf | grep IPv4dev= | cut -d "=" -f2) | grep inet | awk '{print $2}' | cut -d '/' -f 1)

IPv4addr=$(cat /etc/pivpn/wireguard/setupVars.conf | grep IPv4addr= | cut -d "=" -f2 | cut -d "/" -f1)

if [ "$IPv4dev" = "$IPv4addr" ]; then echo "IPv4dev and IPv4addr are equal."; else echo "IPv4dev and IPv4addr are not equal."; fi

Also this one:

pivpnHOST=$(dig +short $(cat /etc/pivpn/wireguard/setupVars.conf | grep pivpnHOST= | cut -d "=" -f2))

remoteip=$(curl -s https://checkip.amazonaws.com)

if [ "$pivpnHOST" = "$remoteip" ]; then echo "pivpnHOST is updated."; else echo "pivpnHOST is outdated."; fi
