      Port Forwarding On More Than One PC?

      Hi all

      Having a nightmare with my router and port forwarding.

      I am trying to open all TCP and UDP ports for 2 wireless PC's. What I am finding is that having all ports open for just one PC is fine, but when I try and assign another PC to all the ports aswell, then I find both PCs are behind closed ports.

      Surely the router can open a port to more than one PC? The more I change settings, the more the router has wobblies and dont work at all and I have to reboot router.

      Can someone please advise me if I am doing anything wrong? Or has someone experience the same problem? If you need more information for me please ask.

      Thanks

      You can't forward the same port to more than one IP address.

      Hi, When you say "all TCP and UDP ports" do you really mean "all" ports? What on earth are you doing to warrant needing all ports open!! :-)

      Re: Port Forwarding On More Than One PC?

      Well if you really mean open ALL ports and it works for one pc, just stuff the other into the DMZ, this will open all ports for that also.

      If you mean that you are setting up for torrenting on both, then simply configure two seperate services on the router Utor1 and Utor2 for example. Make sure the Laptops are always getting the same IP's everytime, then setup two lots of port forwarding in the router.

      If this is what you want and i have not explained very well let me know and i'll do a detailed explanation.

      Re: Port Forwarding On More Than One PC?

      To warrant all ports to be open is because I have firewall and antivirus software installed on each PC so I find it easier to open the router up fully by selecting the all TCP and all UDP. That way I only have to worry about configuring the firewall software then.

      I did try assigning one PC to all open ports and the other using DMZ, but it simply closes everyt port up as before.

      I am not using the PC's for torrents, its for hosting online game servers. Just would have been nice to have both gaming PC's opened up on the same ports. Its a shame you cant just turn off the firewall on the router completely cause that would be better for me.

      Thanks to all that replied to this post.

      You.are.mad.



      You are virtually begging someone to try and break into your network by opening the ports on the router. Plus, you are giving yourself twice as much work to do by having to configure the software firewall on 2 machines rather than simply opening a few ports once on the router.

      If I were you I would dump the software firewalls and configure your router properly.

      Re: Port Forwarding On More Than One PC?

      Sounds like I am doing it all wrong then bud. Aslong as the security of the firewall is the same as on the router then I will do that. Just seemed that the software on my PC was better.

      lol As you can see I am not someone who knows the in's and out's of this sort of stuff, but from your input, I can learn more and more. Thanks.

      Re: Port Forwarding On More Than One PC?

      Sorry, I wasn't terribly subtle was I?

      You are already a step ahead of the game simply by having a firewall on your PC - so you are aware of the dangers of open access to your machine. I just wanted to get across that you'll find the router provides much more effective firewall than anything you have running in software on your PC. By setting up the router rules you can effectively make your network invisible to the outside world apart from those selected ports you want to use for gaming or filesharing.

      The primary advantage is that you are stopping rogue traffic before it gets to your PC rather than letting it get past the router and relying on your PC firewall to deal with it. The other major advantage is that you can do it all in one place.

      Software firewalls have their place (particularly on laptops as your firewall is portable), and there isn't really any harm in having one running on your PC in addition to the router.

      Thanks for the more subtle post

      One question, is there any ports I should open that I am not aware of like for MSN, Xfire and any internet things?

      I will change the way I think of firewalls now and try the new method. Thanks again.
