I have a modem-router device, Siemans, and 2 hardwired computers.

Computer #2 will not connect to online Halo servers anymore, in the Internet Servers list, all games tend not to have Pings

Computer #1 is fine, can connect and see pings.

I programmed the router to open the ports 2302 and 2303, still Computer #2 will not connect to online Halo servers anymore, however somehow it worked 2 days ago, then nothing again.

Computer #1 ports opened (default) UDP 2302 and TCP 2303
Computer #2 ports opened UDP and TCP 3333 and 3334

If you running Vista you should try playin halo as an administrator also disable UAC as that causes alot of problems.

If you running XP my advise would be to see if the window that asks to keep blocking or unblock appears and click unblock as that a problem with almost every game program you play online with Windows XP.

Macintosh computer I wouldn't know since I never ran into an issue running anything on a Mac.

Running everything as administrator and disabling the UAC is the single most asinine thing you can do. It essentially disables all security and allows any malware/virus program free reign to infect and damage the PC. There is absolutely no valid reason to run standard programs as administrator.


Check to be sure that Computer 2’s software firewall is allowing access to HaloCE.exe and/or that your Internet security/anti-virus program is allowing HaloCE.exe access.
