GE DVMRe CT II User Manual page 60

In order to use Dynamic DNS with GnuDIP, the user has to configure following in the menus:
NOTE
•
Name Service must be set to GnuDIP (Ethernet Setting Menu).
•
Primary Name Server must be set to the IP address of the GnuDIP server (Ethernet
Setting Menu).
•
Hostname must be set to the required hostname format e.g. ge04.companyname.net.
For registration purposes, the string until the first dot is used as hostname (here: ge04),
the remainder is used as domain (here: companyname.net). The hostname is set via
the Ethernet Setting menu and is case sensitive.
•
DDNS update interval must be set to a reasonable value (e.g. 2 minutes).
•
The password for the DDNS server has to be set in the Passwords->DDNS password
menu. The password is 4 digits long (The Enter button can be used for the number 0).
When everything is configured correctly, the DVMRe will send periodically a Dynamic DNS
update message over TCP port 3495 to the Dynamic DNS server telling the server its
hostname. The DVMRe does not include its IP address in the message. Instead the Dynamic
DNS server extracts the IP address of the DVMRe via the Ethernet source IP address. This
guarantees that the correct IP address is used even when the DVMRe is behind a NAT router.
Main Menu → Communications → Ethernet Settings
Use this menu to configure the Ethernet Advanced communications settings. Select from the following:
Bandwidth: Local bandwidth control, set from 5Kb per second through 250Kb and Unlimited. The
minimum of this setting and the setting requested by WaveReader will be used.
TCP MTU Size: Select from Standard, 1400, and 1200. The MTU describes the maximum possible TCP
packet size. Standard (1500) is optimal for most ethernet network environments.
