Thank you for reaching out! Depending on which modem you have with us, the Port Forwarding settings may be located differently. You can access the modem UI with the steps here. The specific set up steps are outside our scope of support. We do have a customer post here that has had great success in setting it up. Others in our Community may want to chime in on this.

Hey bud, goto portfowad.com they got some good information on how to setup port forwarding.
Also if you are using a shaw modem/router combo then I'd recommend getting your own router and bridging their modem. It's not mandatory but you get more control with your own router.
