I am still not lucky with enabling WUDO between Fusion guest and a peer operating in physical LAN the Fusion host is connected to.
All WUDO peers have their firewalls open for all types of WUDO traffic.
Guest's host OS has it firewall open for inbound traffic coming to 'vmnet-natd'.
WUDO peers are configured to look for Windows updates in Internet, however LAN's gateway to Internet has its firewall closed for WUDO peer2peer traffic.
In Fusion port forwarding is set for ports 7680 and 3544 (WUDO service default ports).
If to take look into statistics in WUDO gui all peers gathered updates from Microsoft so far. According to same statistics one peer made about 250MB of WUDO uploads to PC in local network,
however there is no peer in network which would have this amount received from some peer.
No glue which elements else my setup lacks.
Can I miss some additional service to be run on each peer?
Does "Share with my Mac networking" support
For something like that you might need to use bridged networking. The mac firewall may be blocking it.
