Before making any changes to my roouter (HUAWEI B68A), I tried the webserver example to test the ethernet shield. Every thing works perfectly on local network.
After that, I tried to make it accessible from WAN and here i got some difficulties.
My router is synchronised with no-ip so my ip is "static".
After port forwarding, the arduino is no longer accessible from local network unless i add :portnumber after the ip adress.
When trying to access arduino from wlan (routerWANIPadress:portnumber) i get different different types of errors (such as: err connexion time out, or resource (ipadress) is online but does not respond to connexion request...)
I tried many things (disabled antivirus and firewall, changed port numbre or ip adress, used smartphone and pc, used arduino uno and mega...) but still no solution.
/*
Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)

** Router configuration:
Noip synchronisation :
Port forwarding:
Network security setting:
Serial communication (ok):
Local network test (ok):
WAN access test (error):
When running windows network diagnosis, it says that the ressource is online but does not respond to connexion attemps.
I tried DMZ activation et completely disabling the firewall but it is not working.
There is ACL window to set rules for connexion. Here i find http, https and icmp service types for lan, but only https for wan. could that be the problem?
when i use port 80, i can access the arduino web server directly from the ip adress from local network. when i use other prots, i need to add :portnumber after ip adress to access from local network, is that normal?
Some people say that such problem are related to my ISP (ooredoo) public ip management policy. i don't know if this is wright.

Yes.
i forgot to mention that i'm using a 3g connexion.
a friend of mine has just told me that i can not do portforwarding using a 3g connexion, is that true?
