About NAT-type... I obviously have a switch with blocked ports, as the internet provider says none of their modems/routers have blocked ports, and ive opened the ports in the router manually.. It is a Dexlan 8 ports switch.. Help?
 
A switch has no concept of ip address or ports. It only knows mac addresses.
Besides there is nothing you can configure on your switch it is unmanaged. This pretty much means it is stupid it takes things in one port and sends them out another. It does not even look at the data other than to figure out which machine to send it to.

 
As bill said the switch has no ability to block ports, it would not even reject a bad IP configuration because it does not care about IP addresses. A switch is a very basic dumb device that takes an input from router and has the ability to extract the mac address out of the Ethernet data packet to know which port to send the data (it has a table that keeps track of which mac address is plugged into each port). The ONLY way the switch can be an issue is if the port is physically damaged. This can easily be troubleshoot by moving the cable of a non-working PC to a different port on the switch, if it now works the port was broken, if it does not work then the issue lies elsewhere.


Lets back up and tell us what your problem is specifically, and what networking equipment you have, and if you have done any troubleshooitng
 
I feel stupid atm, there was nothing with the switch - correct.. But the ports werent opened properly in the router... problem is now solved by someone who knew what he was doing xD the lesson is: doublecheck your udp/tcp always..... 😉 thanks for trying guys! :)
