6.2 IP address settings
The IP address settings of capt
2
web must be changed to fit the requirements of the network capt
2
web is connected
to. Please check with the network administrator to find out about the correct settings in order to prevent IP address
conflicts. An IP address conflict occurs when two clients (multiple capt
2
web or capt
2
web and PC) in a network use
the same IP address.
It must be ensured, that an unique IP address is assigned to each capt
2
web within
the network. Upon an IP address conflict, the network may not work properly for a
longer period, even after the failure has been removed.
Two possibilities exist for the IP address configuration:
1. Static IP address
The IP address and the subnet mask are entered manually.
2. Automatic IP address configuration using DHCP
All settings are assigned by the local DHCP server.
Figure 6.1: Static IP address settings
If a
static IP address
is used, the IP address and the correct Subnet Mask must be entered. See figure 6.1 .
If capt
2
web should be accessible from another network, then the gateway IP address must be entered. This is also
to set in case capt
2
web should be accessible from the Internet through a router. Make sure to install port-forwarding
on the router and to set the IP address of the router as gateway IP address in capt
2
web .
Figure 6.2: Automatic IP address configuration using DHCP
If the IP address should be assigned dynamically through DHCP , switch "Automatic (DHCP)" to "Yes" (see figure 6.2 ).
Note that all IP address information will be retrieved by the DHCP server in the network, such as Subnet mask
