Hello, i called on primetel 133 and they explained to me that ports from 1025 until 60000 are open and forwarded on the ip 192.168.2.10 (if you want you can ask the to open all the ports).
So if you want to access your pc remotely, or use p2p programs, then you need to enter the following manually ip settings:
IP Address. . . . . . . . . . . . : 192.168.2.10
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.2.1
DNS Servers . . . . . . . . . . . : 217.27.32.196
217.27.50.125
Something else because all the ports go to one ip if you need more than one pcs to have open ports then you can put a normal router on the modem with the ip 192.168.2.10 and connect your pcs after the router with ips 192.168.2.11 ... then you can forward from your router the ports you need to the ip that you need.
