I've tested this and the firewall does block the netbios ports ok. Is there
any other way to communicate with a pc other than ports? i.e. are all ISP
users on the same subnet and can UNC names be used? Netbios is exposed
without F&P sharing but not sure how vulnerable this is on it's own.

It's only ZAP that provides ICS/NAT support, the free one doesn't. Hmm,
intrusion detection and logging will be my next hurdles, just knowingly
blocking all known holes is my immediate goal, and with the conflicting
advice chucked in I'm making slow headway.
Thanks for your help on this, x y. I appreciate it.
