Are udp packets with non-routeable ip addresses valid on public network?

I am receiving unsolicited inbound udp packets with a "to ip address"
[10.0.10.1] of a computer on my LAN. Is this valid? Other tcp/udp
packets from that LAN computer pass through the firewall NAT as
expected. I added a firewall rule to block that packet and their are no
outward signs of problems with that LAN computer.
On other LAN PC's that run ms/windows and facebook or yahoo are sending
out bound udp packets with "from ip address" containing their LAN ip
address. I bock these also without any outward signs of problems. These
packets are not being NAT'ed like other udp packets from that LAN PC are.
I though non-routeable ip addresses are invalid on the public network.
Any ideas on what is occurring here?
