Hello,
I just bought an TP-Link WR841N. Although, i had this ugly problem from CD with Checking network status, i succeded connecting to the internet from browser. The internet cable from pillar (outside ) goes into this device Huawey EchoLifeHG865 and from there into my router and then the cable comes into my router (TP-Link) . The connection, is good, there is no setup problem here.





My problem:
I can not open ports:

What i tried:
1) Open cmd->ipconfig -Repember IPV4/Default GateWay








2)Login into TP->Forwarding->Add port>Save-Check via Canyouseeme/yougetsignal-No port open





3)Set up my ip static




4)Try to disable /enable windows firewall or enable/disable DMZ(no succes. Atm DMZ is disabled)





Before i had a belkin router and i had no problem in opening ports. What Am i doing wrong here? Any help/tips are welcome.
