Thank you, both ("Blackwolf" & "pch.shot") very much for you input.
However, I couldn't get any of it to work, even "Firestarter!"
I FINALLY found the terminal script (formula) from back when I was trying-out Mint 11, and IT WORKS LIKE A CHARM, in Ultimate Edition 3.0 as well, for both 'wifi' and hard-wired Internet connections. And you folks may well wish to take note of this one, for both 'file-sharing' and 'printer acquisition,' via a LAN. (I, BTW, didn't figure it out - it came from "altair4" in the Mint Forum. He [or she] figured it out.)
First, "Enable" the Firewal and then set the Firewall's "Incoming" to "Deny;" and set the "Outgoing" to "Allow." At least, that's how I did it!Then, here is the terminal formula for resolving the on-board Firewall issues relative to 'file-sharing' and 'printer acquisition,' via a LAN...

Give this a shot:
[1] Allow samba access
Code: Select all
sudo ufw allow Samba
[2] Allow CUPS access
Code: Select all
sudo ufw allow CUPS
EDIT: The capitalization of "Samba" and "CUPS" is important. To get a list of all these preset firewall rules and how they are spelled:
Code: Select all
sudo ufw app list
[3] Fix an oversight in the default firewall configuration
Edit a file as root:
Code: Select all
gksu gedit /etc/default/ufw
And change this line:
# extra connection tracking modules to load
IPT_MODULES="nf_conntrack_ftp nf_nat_ftp nf_conntrack_irc nf_nat_irc"
To this:
# extra connection tracking modules to load
IPT_MODULES="nf_conntrack_ftp nf_nat_ftp nf_conntrack_irc nf_nat_irc nf_conntrack_netbios_ns"altair4

Hallelujah!!!
I'll leave this up for a few days for reference and then close it out - SOLVED. OR, if the Administrators want me to mark it SOLVED asap, I'll of course comply.
Once again, thank you ALL so very much for your help!
