Assuming I have Snort working properly on this Windows 7 box, how do I connect it to he network?

I have the box configured as 192.168.x.81.  Do I need to use a mirrored port on my network switch?

it can be if you have rules for such traffic and they are enabled as well as
looking on the proper interface...

not everything but... ;)

what some blogs and helpers recommend is to create a local.rules file and then
create a rule in there that will alert on everything... make sure that
local.rules is included in your snort.conf and that it is with your other rules
files with the proper permissions... then restart snort... the "catch
everything" rules would be something like these...

alert icmp $EXTERNAL_NET any -> $HOME_NET any (msg:"icmp traffic inbound";
sid:1; rev:1;)
alert icmp $HOME_NET any -> $EXTERNAL_NET any (msg:"icmp traffic outbound";
sid:2; rev:1;)
alert tcp $EXTERNAL_NET any -> $HOME_NET any (msg:"tcp traffic inbound"; sid:3;
alert tcp $HOME_NET any -> $EXTERNAL_NET any (msg:"tcp traffic outbound"; sid:4;
alert udp $EXTERNAL_NET any -> $HOME_NET any (msg:"udp traffic inbound"; sid:5;
alert udp $HOME_NET any -> $EXTERNAL_NET any (msg:"udp traffic outbound"; sid:6;
alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"ip traffic inbound"; sid:7;
alert ip $HOME_NET any -> $EXTERNAL_NET any (msg:"ip traffic outbound"; sid:8;

"any" used to be allowed as a protocol but when i tested it just now with snort, it didn't like it at all...

you'll want to disable these as soon as possible and restart snort ;)
