I am having trouble with Tivo being blocked from updating by Webfilter. Temporarily, I have added a bypass through Webfilter for the Tivo IP address and it works fine. I'm not sure I want to leave that bypass there forever so I would like to fix the issue with Webfilter.

When I log the blocked sessions, it looks like the Tivo attempts to contact its external server for updates and is blocked with a filter prefix of invalid_blocked. From what I can tell, the forums seem to say those are malformed packets or similar. But I don't care how the packets are if they are going from Tivo to it's master site, correct?

Is there a policy or line that I can update or change in Webfilter to allow this to work for Tivo without having to bypass Webfilter with the Tivo internal IP address?

Thanks!
