DESCRIPTION
Network Address Translation (NAT) allows the translation of an Internet
protocol address used within one network (for example a private IP
address used in a local network) to a different IP address known within
another network (for example a public IP address used on the Internet).
Select this checkbox to enable NAT.
Select this check box to turn on IGMP (Internet Group Multicast
Protocol). IGMP is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data.
Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group
Multicast Protocol) is a session-layer protocol used to establish
membership in a Multicast group – it is not used to carry user data.
IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC
1112) but IGMP version 1 is still in wide use. If you would like to read
more detailed information about interoperability between IGMP version
2 and version 1, please see sections 4 and 5 of RFC 2236.
Select this check box to set a monthly limit for the user account of the
installed 3G card. You must insert a 3G card before you enable budget
control on the selected device.
You can set a limit on the total traffic and/or call time. The selected
device takes the actions you specified when a limit is exceeded during
the month.
Select this check box and specify the amount of time (in hours) that the
3G connection can be used within one month.
If you change the value after you configure and enable budget control,
the selected device resets the statistics.
Select this check box and specify how much downstream and/or
upstream data (in Mbytes) can be transmitted via the 3G connection
within one month.
Select Download to set a limit on the downstream traffic (from the ISP
to the selected device).
Select Upload to set a limit on the upstream traffic (from the selected
device to the ISP).
Select Download/Upload to set a limit on the total traffic in both
directions.
If you change the value after you configure and enable budget control,
the selected device resets the statistics.
Select the date on which the selected device resets the budget every
month. If the date you selected is not available in a month, such as 30th
or 31th, the selected device resets the budget on the last day of the
month.
