Click Apply and Back.
9. Now Re-enter Setup, Network and NAT/UPnP and see if the ports are active and
remain the same, in both External and Port port columns.
10. If the ports are active, automatic port forwarding has worked. If they are active
but not the ports detailed in step 8 click the Auto down arrow key and select
Manual. Then click on edit signature and change the port numbers to 8240 (Server),
80 (HTTP) and 1240 (RTSP). Then click Apply then Back.
11. Check UPnP ports ( Setup, Network, NAT/UPnP) are the correct ports and are
all active. If they are then port forwarding has worked so go to Process 5. If not,
untick Enable UPnP, Apply then Back and Exit menu completely. You will now
need to do manual port forwarding.
2. Checking to ensure that the PC can see the DVR locally
12. Ensure the menu in the DVR is closed and go to the Windows PC keyboard that is
connected to the router.
13. Ensure the PC is on the network and press the Windows button and the letter R
to open a Command Run box.
14. In the run box type CMD then enter or click OK.
15. A black MSDOS screen will now be displayed with a flashing cursor.
16. Type ping <space> <IPv4 Address supplied by DHCP in step 4> and Enter
17. Check packets sent, packets received and packets lost at bottom of reply.
18. If not 4 packets sent, 4 packets received and 0 packets lost you have a problem
with communication between the PC sending test data through the router to the
DVR and returning to the PC. You can try pinging the router by going to step 13
through 15 and then type ping <space> <IPv4 Default Gateway Address>
supplied by DHCP in step 4. The IPv4 Default Gateway address is the router
local address. If packets are still lost the problem is no/bad connection between
PC and router, but if okay then problem is between router and DVR. Do not
proceed further until 4 packets sent, 4 packets received and 0 packets lost is
displayed.
3. Setting up port forwarding
19. If the NAT/UPnP option has not worked, then port forwarding will have to be
done manually. The purpose of port forwarding is for the router to allow
communication on a predetermined incoming port received on the external side of the
router, to be passed through the router firewall to the local address of the DVR. The
DVR will process the data and return it to the router using the IPv4 Default Gateway
Address which is the router’s local address.
