Using UltraVNC with Comodo

I am using Comodo firewall and cannot get ultraVNC to work. It works fine if I disable the firewall. Anyone have thoughts on how to configure this? I tried many things with no result.
Thanks

I’m also using UltraVNC, but not having a problem with Comodo. In the network monitor section, make sure to allow connections to your UltranVNC listener port (I used 5500). Hopefully this will solve your problem.

Cheers,
