I just moved the board to physical hardware in my apartment and I'm working on
locking it down - I have peerblock running and am using it to block russia,
czech republic, Romania, China, Taiwan and the Ukraine - that's where almost
all of my crap connections come from. The docs are a little confusing so I
wanted to ask here since I know others use it..

I added these countries to the List Manager (along with a few others: spiders,
Open Proxies, and the Cruzit Web Attacks lists) so far that's almost 450M IPs.
I hope that's enough. :)

Anyway, I get confused with the Port Settings tab - I think I have it correct
since it seems to be working, but thought I'd confirm... on the Port Settings
tab I have all Default Ports selected (they were not by default -
80,443,21,25,110) and I added some for the BBS in a group called "BBS Ports" -
these include 22, 23, and 504 (which I use for another BBS). I have a check in
this box as well and it's selected to "Allow from" Outgoing.

By placing checks in these, am I disabling blocking these or enabling them? THe
instructions weren't clear (to me at least.)

Also, I do not allow my users to check mail via POP3, can I close that service
altogether via Synchronet Control Panel or does network traffic use it for
something? I figure SMPT needs to be enabled so that I can recieve email that
is sent to the board from outside addresses.

If POP3 is needed for the board to send out - I guess I could block incoming
POP3 connections? I'm just sick of spammers hitting that port all day. :)
