Using Tablo Connect with Max BR1 Mini

I have a Tablo OTA DVR at my house, & can connect to it with my phone, or with a firestick over any wifi connection except my Peplink Router. I have a Starlink connected to the WAN port, & a Verizon sim card in the router. All other streaming services work fine, but the Tablo. Maybe there is a setting I need to change?

Thank You
