7 Troubleshooting
7.1 Web Page Not Found
7.1.1 Private Network
The following are possible reasons for communication with an ipGateway to fail when used on a private network
(LAN).
7.1.1.1 IP Address Incorrect
Check that the IP Address used to navigate to the ipGateway matches the IP address in the configuration file.
7.1.1.2 Subnet Mask Incorrect
Check that the Subnet Mask the ipGateway is using is correct for the network it is connected to.
7.1.1.3 Octal Addressing
IP address with leading zeros are treated as octal (base-8) numbers
The address 010.011.012.013 is converted to the decimal address 8.9.10.11 rather than 10.11.12.13.
7.1.2 Public Network (Internet)
The following are possible reasons for communication with an ipGateway to fail when used on a public network,
i.e. the internet.
7.1.2.1 Public IP Address Incorrect
Check that the public IP address used to connect to the ipGateway is correct.
This address is normally the public address of a router on the network to which the ipGateway is connected.
7.1.2.2 Subnet Mask Incorrect
The ipGateway is configured with the wrong subnet mask.
7.1.2.3 Default Gateway Address Incorrect
The ipGateway has the wrong default gateway address. This means that it cannot send any data to an external
network, such as the internet.
7.1.2.4 No NAT Setup
The router used to accept incoming requests to the ipGateway does not have any address translations setup.
See section 2.1.1.1
7.1.2.5 NAT Setup Incorrectly
The router used to accept incoming requests to the ipGateway has a NAT setup, but the details of the NAT are
incorrect.
Check that the NAT contains the correct IP Address and Port information.
7.1.2.6 Incorrect Port Specified In Browser Address
Check that the correct port is specified in the address when navigating to the ipGateway.
See section 2.1.1.1 for a description on how to specifiy a particular port when navigating to the ipGateway.
7.1.2.7 Octal Addressing
See section 7.1.1.3
