Hardware firewall

[Gsmax]

I,m thinking of installing a hardware firewall between the optical network terminal and TM3200 router. The particular hardware is Firewalla Gold. This would require configuring the TM3200 router in bridge mode. Would this configuration work with Optik TV?

• Disregard this question. I have subsequently found that Firewalla hardware firewall is not compatible with the T3200M router. Is there a hardware firewall compatible with T3200M?
