    Well it meant to be used with your modem so sure it will work keep in mind the USG20-VPN might not get more then 200Mb or less TCP speed from it. With the router you have does it do NAT? Was you hoping to firewall devices from the router? can NAT be disabled on that router or  can be used as AP by not using the WAN port.

    Welcome to Zyxel community.
    It should be OK. But if you would like to deploy the more powerful UTM service in your environment, you could consider our USG Flex100 model.
