9.1.3 IP address settings
Faulty IP address settings or a disabled ICMP can impede con-
nections to your system.
Reasons
|
A syntax error in the IP address settings occurred in the
ip.cfg
file.
|
The netmask was not set correctly in the
ip.cfg
file.
|
The Internet Control Message Protocol (ICMP) is disabled
in your network.
|
The IP address is used more than once in your network.
Symptoms
|
The system is not accessible via GATE Manager or FTP.
|
The ping command does not work.
Solution
|
If ICMP is disabled in your network, please enable it and
check whether this solves your problem.
|
If the problem still exists, change the IP address using
Quickstart.
9.1.4 Firewall issues and NAT / PAT settings
Very often, firewall settings in your network prohibit access to
your VoIPBox. Network address translation (NAT) or port ad-
dress translation (PAT) issues can also cause connection prob-
lems.
Reasons

The configuration of your firewall blocks access to your
system.
|
NAT / PAT settings block access to your system.
