I have not downloaded your manual (I don't know which model it is and I'm on 31.2 Kbps dialup and no doubt its a huge pdf file...
) so I cannot tell you what chapters to read. If you tell me exactly what model and revision your router is I can take a few hours to download the manual and point out the salient sections.
Preferred setup:
- Set the router to allow pings from the WAN.
- Disable UPnP on the router.
- Configure your LAN IP address statically outside the range of your router's DHCP server, but under the same netmask.
- Forward ports 2300-2400 TCP&UDP and 47624 TCP to the machine you will play OP from that you just configured with a static LAN IP.
Presto! You're good to go.
Alternate setup:
- Set the DMZ host on the router to the static LAN IP address for the machine you will play OP from.
If you are unsure of how to configure your PC with a static LAN IP address (it should be outlined in your rotuer manual), just ask and I'll try to explain it.
Sorry if I seem short about this but it happens over and over and over and over... I just grow a bit weary of it sometimes when I know its all explained in most router manuals. (thus the origin of the tech support abbreviation: RTFM!
)
