Has anyone ever found any answer to this annoyance???
I have virtually the same thing happening. I will see programs that don't need Internet access asking to access 184.108.40.206, or... I see them ask for access to 192.168.xxx.1 (my wireless Linksys router, WRT54GS). I have reset my ZA database. Most of the time I just deny access. This is a relatively new install of the latest free ZA... on a Toshiba notebook with Vista Hm Prem clean install. What's interesting is that I am seeing programs, that I've just started up, soon asking for multicast permission.
Here's a good one... I'm formatting a terabyte hard drive in a cmd line window... later the format command is asking to multicast... like, as if...
Eventually, I'm going to get tired of this obnoxiousness... and go try a competitor. I used to use ZA and recommend it, until ZL took so long to get a Vista version out, my Pro sub expired while waiting. Ran for a long time on just Vista Firewall, but finally decided I'd try ZA Free again. I see a tech article on Ars Technica says to just use the Vista Firewall for soft firewalling. Doesn't matter if I cable up or use my notebook's wireless... ZA keeps on alerting me how blabulous my applications are... whether to multicast or to the Linksys router. Doesn't matter whether I set ZA to disable WinFirewall or not.
I certainly can't block access to my router address... and dunno where the free ZA would let me kill off 220.127.116.11... and why anything... uh, I mean -every-thing ...wants to multicast. Seems like a ZA bug to me.
