Configuring Comodo Firewall 6.x with mobile hot spot software

I’ve configured Lenovo’s mobile hotspot software to allow other devices to connect to the Internet using my Thinkpad Helix’s (Win 8 x64) Internet connection.

I can successfully connect and get an IP with other devices if Comodo firewall is running with my Custom Ruleset enabled. However, the other connected devices cannot connect to the Internet unless I disable Comodo firewall on the Helix.

Can anyone provide some guidance on whether/how I can create a new rule to allow these devices to connect to the Internet without my having to disable Comodo firewall on the Helix.

Thanks,

Regards,
Charles
