We have tried to portforward on both ends every port that we need we have no firewall on we tried minecraft just then and it didnt even say they were connecting nothing i dont know what to do anymore i use a belkin wired router from my isp Iinet my friends went out and replaced their modems but nothing its always the same thing it times out were in the same country same state one of my friends is down the road from me still no connection

to be honest im on the last place i can ask now ive tried everything im in a college doing a cert 4 networking class and i still dont understand whats the problem please please please help me

thankyou.

There is another possible, that your ISP is blocking users from receiving data packets on specific ports or protocols to you.

EDIT:

Forgot to mention if your router has QoS engine enabled, use that, if not then look at Application Rules instead of normal Port Forwarding.

sorry for barging in guys. not sure if this is right thread..but since there's talk here off net connectivity etc. thought i'd ask.

i have a BB modem that has 4 LAN ports at the back and is a wireless router as well. i'm using a LAN cable to connect it to my laptop. how do i identify its port number in my system...u know like 54xxxx or something like that?

UPnP is definitly on

and QOS engine is enabled do i need to do anything special with it

If DMZ is not working, then there is a problem somewhere blocking traffic to you.

When setting your ports did you allocate your local address to your PC? Perhaps that has changed since you first set the ports?

Failing that, maybe talk to your ISP.

i may have to talk to my isp now thanks for the help man
