Following guide can help you in two situations:
1) Port forwarding is does not workingwork
2) Remote access to 2N® EasyRoute / 2N® SpeedRoute web interface is does not wokingwork
Step 1: Check settings
Check that Firewall is enabled
By default the 2N® EasyRoute / 2N® SpeedRoute is protected when someone is trying tries to access it from the private range of IP addresses (via WAN port = UMTS or WAN4/WAN1). Therefore If if you have set the Port Forwarding but still you can 't not access any of the devices connected in the specific port (even if you can ping them), you need to deactivate the protection in the 2N® EasyRoute / 2N® SpeedRoute
In order to do so, go to the Menu SETUP / Network / Firewall / Basic and UNCHECK the the parameters "Check SYN-Flood" and "Check Spoofing"
