forwarding 2 ports to a LAN IP address using a 3com OfficeConnect ADSL Wireless 11g Firewall Router?

Question

HI,

So I have 2 ports which my application needs to use say 16543 TCP & 16544 UDP which I need to forward to one of the PC's on my LAN say 192.xxx.1.2

Does anyone know how I can do this with the above router I can't seem to find a usefull guide anywhere.

Cheers,
Steve.

brill - thanks yahoo I found it on that site.

unfortunately I'd already done it right but it's still not working so there must be something else wrong - at least I've ruled that out now :-)

Cheers,

Here is the link to see.
I'm sure the instructions are the same with your router.

I believe you are only slightly familiar with the concepts you are discussing. Perhaps a recap will help you. Wired routers assume all that are plugged into the LAN have permission to be on the LAN. This is because the physical connection is by wire and this is by its nature more easily controlled. If you do not want someone on the LAN, you unplug them from the network switch. Of course this keeps them off the LAN entirely, not just off the Internet. Wireless routers assume that there is no simple physical layer connection that can be unplugged. Wireless signal can pass through windows, walls, property lines, etc and this can permit anyone within signal distance to access the LAN. Because unauthorized access can and usually does result in problems of substantial dimension, wireless routers have means of blocking unauthorized users via encryption, preshare key, and MAC validation. If a wireless user does not match the security steps, the user is denied total LAN access which includes Internet and all other LAN access. It does not permit LAN access for file transfer, for example, while it blocks Internet access. Having said all the above: 1. There is no way, with wired or wireless routers, to block someone from Internet access and permit LAN access. 2. If you wish to block someone who has a wired access from accessing the LAN, unplug the individual at the network switch. 3. If you wish to limit Internet access, you will need another appliance, a web blocker. These can be fairly flexible in what they permit and what they block but the discussion of these is beyond the scope of this question.

Answer 3

Usually that's configured from the administrative interface- just open a browser window and call up your router's IP address- like http://192.168.1.1/ Check your user guide for the router's default admin password.

Port forwarding is usually found under advanced options.

Make sure that Windows Firewall is also set up to allow these ports as well
