Toy firewall produces toy results. What you show isn't all that informative.

Some Taiwanese clone manufacturer, probably a RealTek 8139 chipset (a common 10/100BaseT NIC) - the 01:00:5E is a Multicast destination, relatively meaningless because of the lack of IP header information.

192.168.2.5 is on your network somewhere - 239.192.152.143 is am "Organization-Local Scope" multicast address - see RFC2365. It's UDP with a source and destination port of 6771 - which is relatively meaningless without knowing what software you've installed. The "data" you show appears to be a BTrieve request, but you'll have to figure out why your "192.168.2.5" host is attempting to send this as a UDP datagram to a local multicast - as that doesn't exactly smell right.

So, what did you install on your windoze box?
