Hello
I have a problem with ports not remaining open after having them forwarded.
Ok my setup is like this:
MY PC<-LAN<-Asus router<-LAN ZTE router<-internet
I have port forwarded the 2 routers as shown in some tutorials on the internet.
The ip's are like this: internal IP for the zte router is 192.168.1.1 and for the ASUS router is 192.168.2.1
I set an static IP adress for the asus router(192.168.1.121)and port forwarded on the zte router using that Ip that i set.(Let's say i have port 80 open both TCP and UDP.)
On the Asus router i portforward the port 80 on the IP that my computer has 192.168.2.134.

Now comes the big inconvenience.I used 2 sites to check if that port is open or not(canyouseeme.org and yougetsignal.com).
They both show that port 80 is closed.After checking i take the tool PFPortChecker (made by portforward.com) and check port 80 and it says it is open.After coming back and checking on the 2 sites they both show that port 80 is open -___-.
I tried adding another port 443 this time took the same steps and the same thing happened.BUT after checking port 443 i went back on the 2 sites to see if port 80 was still opened and it wasn't.It only seem to open only after using the PFPortChecker tool.

Please help!

EDIT:i tried a diffrent site for this(http://www.ipfingerprints.com/portscan.php) and it shows that my ports are filtered even though they are allowed through the firewall.

I don't have such an option on any of the routers(except for ipv6 spi on the zte but it was already disabled).
I tried turing off the firewall for the asus router and nothing changed(i can't too much on the zte router since the interface was limited by the ISP)
