4.10.3.1 IP Filter
IP filter interface is shown as in Figure 4-120. You can add IP in the following list. The list supports max 64
IP addresses. System supports valid address of IPv4 and IPv6. Please note system needs to check the
validity of all IPv6 addresses and implement optimization.
After you enabled trusted sites function, only the IP listed below can access current NVR.
If you enable blocked sites function, the following listed IP addresses cannot access current NVR.
Enable: Highlight the box here, you can check the trusted site function and blocked sites function.
You cannot see these two modes if the Enable button is grey.
Type: You can select trusted site and blacklist from the dropdown list. You can view the IP address
on the following column.
Start address/end address: Select one type from the dropdown list, you can input IP address in the
start address and end address. Now you can click Add IP address or Add IP section to add.
a) For the newly added IP address, it is in enable status by default. Remove the √ before the item,
and then current item is not in the list.
b) System max supports 64 items.
c) Address column supports IPv4 or IPv6 format. If it is IPv6 address, system can optimize it. For
example, system can optimize aa:0000: 00: 00aa: 00aa: 00aa: 00aa: 00aa as aa:: aa: aa: aa: aa:
aa: aa.
d) System automatically removes space if there is any space before or after the newly added IP
address.
e) System only checks start address if you add IP address. System check start address and end
address if you add IP section and the end address shall be larger than the start address.
f) System may check newly added IP address exists or not. System does not add if input IP
address does not exist.
Delete: Click it to remove specified item.
Edit: Click it to edit start address and end address. See Figure 4-121. System can check the IP
address validity after the edit operation and implement IPv6 optimization.
