Hi Rance,

-----------------------------------
quix0r at quix0r:~$ ping free-search.homelinux.org

-----------------------------------

That IP can also be found in my router if I do a "ifconfig ppp0":
-----------------------------------
root at firebox:~# ifconfig  ppp0
ppp0      Link encap:Point-to-Point Protocol  
          inet addr:94.221.128.75  P-t-P:94.221.128.1
Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1492  Metric:1
          RX packets:297666 errors:0 dropped:0 overruns:0 frame:0
          TX packets:260764 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3 
          RX bytes:144019836 (137.3 MiB)  TX bytes:49914220 (47.6 MiB)
-----------------------------------

So all looks fine to me. BTW: Do you need some settings? I enabled IDS
but disabled it for port 8080 so it should not affect it.
