I believe my router or DSL modem has been compromised. I'm basically a
newbie when it comes to security and setting up a server, but I set one up
just to mess around with it. I'm not real worried about someone getting
info off of my machine, but they are really slowing down my connection and
it's annoying! Here's my setup:
Win2K Server running IIS5, Exchange 2000, ZoneAlarm 3.x (with several shady
ports open: 113 and 25), Netshield w/latest defs, DNS2Go dns forwarding
enabled (advertising...come crack me!!! bad, I know)
Mac OS X 10.1.5 with Brickhouse firewall
Alcatel Speed Touch Home with 3.2.7 firmware
Linksys BEFSR41 with 1.42.7 firmware (port 113 and 25 forwarded to LAN)
->Win2K Server
Alcatel->Linksys
->MacOS X
Anyone have any idea what happened? Let me know if I missed anything. I
found that port 1900 was SSDP, but I'm not sure what that even does. Also,
my Win2K box has all the latest patches for Win2K, IIS, IE,
Exchange, etc., long & difficult admin password, iislockdown run, etc.
ZoneAlarm trusts the network (192.168.1.X...bad idea, I know) and doesn't
prompt when a new app hits the network (also bad, I know). That feature was
crashing my ZoneAlarm.
I tried restarting the router, but the traffic seemed to just continue.
I'll try some of the Alcatel updates later:

Does anyone have any idea what could be causing this?
Thanks in advance,
Aaron
