1. Can anyone please tell me exactly what ports need to be opened for my 9000 series Eyemax DVR to broadcast correctly? I originally set up my no name, Verizon branded modem/router to use the ports listed in the DVR UI, but it refused to configure properly and thus was forced to set the DVR on a DMZ, wide open without AV.    Ran great for a year, now it keeps getting hit with viruses every other day.    
  
2. What (if any) AV could (or even should?) be used on a PC based DVR?  
  
3. What is the safest way to setup a networked DVR?  
a. On DMZ with windows firewall and/or AV configured? 
b. Behind the router w/FWDing and windows firewall disabled? 
c. Behind the router w/FWDing and windows firewall enabled? 
d. Other? 
  
  
  
Eyemax 9000 series 4 channel DVR (OEM) (exact model unknown) 
Single IP (dynamic) 
DYNDNS service running 
Verizon branded modem/router (exact model unknown) 
  
THANKS!
