Can't remotely access my CCTV after upgrading to PLDT Fibr

[kisshmet]

Dynamic DNS mates a FQDN (fully qualified domain name) like yourname.dyndns.com to the dynamic IP address assigned to you by your ISP

With dyn dns you can use the fqdn even if the ip address assigned to you by your isp changes over time

Requesting a static ip address lets you have a stable mode of internet address but you still have to get a domain name matched into that static ip address for you to be able to utilize a fqdn (e.g. yourhousename.com) to access your cctv remotely.

Even if you all these things in place, ip address, domain name you still have to make sure that your isp does not block the port your cctv monitoring application depends on

How will I check if my ISP blocks the port used by my dvr?

this is interesting Topic.. as Im planning to install IPcam at home.. thanks Boybi

you can try network utility nmap .. it will scan open ports on your modem/router..
since naka 4g router ako,,my router address is just a private unroutable IP,so i just rent VPS providing VPN sa hauz at sa office ko,,its just like extending your Lan subnet between your hauz and office or your smartphone..

Just apply for /29 static ip, you get 5 useable ips problem solved.

If you know the gateway which is the ip address of the modem your isp provided to you then a simple telnet command will do "telnet gatewayip# port#" from the command line will do

Remember you need to connect the computer with which youll execute the telnet command to directly to the modem or gateway and you use ethernet cable for that

If there is no response then the port is closed on pldts end in which case you can resort to vpn connection as suggested by other tsikot member here

Yung magandang klaseng DVR or NVR ay may DDNS na assigned so hindi mo na kailangan mag subscribe sa DYNDNS para maging static IP address mo router. Same is true sa IPCAM meron din silang assigned na DDNS. Meron din silang apps na available for android and IOS so madali silang i access sa mobile phone.

Kung kailangan mo lang ma monitor yung place mo na hindi mo na kailangan i set up pa yung router and modem mo, yung IPCAM nalang ang gamitin mo. Can easily access as mobile thru the apps na available para sa IPCAM manufacturer.

I tried to do the telnet in the command prompt but it says "telnet is not recognized as an internal or external command."

Naka DDNS na pala DVR ko. i-dvr.net ang gamit. But since I upgraded to PLDT Fibr, di ko na maaccess mga CCTV ko.

Too bad your windows doesnt carry the TELNET command

Oh well you can try mac or linux

But basically you need to do an end to end check. Connect your DVR directly to the modem provided by the ISP on the end where it is located. Then connect your computer directly to the modem provided by the ISP on the testing end

Assuming you have similar ISP provider end to end and the result of the test is negative then you make the request to open the port to a single ISP otherwise you make the request to open the port to both ISPs your equipments are linked up to.

Opening the ports on the ISP end means opening that port your DVR need to all the routers the ISP control from your computer end all the way to the DVR end

Things get more complicated with 2 different ISPs serving you in one end and the other. You make the request to open ports on both ISPs. This is a cumbersome task to both ISPs

So you are better off utilizing a VPN

The telnet client is not installed by default. You can manually install it in Add/Remove Windows Component.

I tried to access my DVR using my iPhone via LTE and I was able to view the CCTVs. When the iPhone is on wifi with PLDT Fibr (at home), it cannot access the CCTV in the office (also using PLDT Fibr). So is the problem with the PLDT internet?

[12vdc]

What is your iP address obtained from DHCP?. There is a carrier grade iP that sometimes needs port opening on aggregator router. You may try to check the WAN ip by using traceroute or accessing modem to check the WAN iP.

[boybi]

WAN IP 119.95.xxx.xxx
DHCP 192.168.xxx.xxx

Try to subscribe to dynDNS first if it's works for you. They have 7 days trial I think.

Turn on the hotspot of your iphone (connected thru LTE), then connect a laptop to your iphone hotspot and execute the following:

ping [external ip of the cctv]
telnet [external ip of the cctv] [port# utilized by the cctv]

A positive response to both commands will tell you that the cctv is reachable from the opposite end and the port is open on all the routers that connects your iphone to the cctv

Try all those commands in your fiber internet and a negative response on the telnet command means that somewhere among the routers of your fiber connection to the cctv that particular port is closed

To determine how many routers your video data need to pass through issue the 'traceroute [external ip#]' command

Last august pa pala ito and I haven't had time to try this. Wala kasi akong laptop, hehe. But I have asked the supplier of my CCTV and they said I need to call PLDT for them to make changes in the settings for my internet connection. Usually problem daw ito sa ISP side.

Anyway, I have another dilema.

In my office, I use PLDT's fibr modem/router as my DHCP server. Pero mukhang hindi kaya ng modem yung dami ng devices connected, lagi sya nagrereset. So I installed a TPLINK router after the modem and used the router as the DHCP server.

PLDT modem --> router --> computers (+other devices)

IP of modem is 192.168.X.X, router is 192.168.Y.Y.

Everything is ok. All my devices can connect to the internet, and all can access the server.

The problem is, I cannot remotely access my CCTV. I have setup port forwarding for both the modem and the router. Ano pa ba ang kelangan i-config?

I think there might be something wrong with your port forwarding rule

Can you share:
- Specific port forwarding rule you created. what port? where is it forwarded?
- IP address of the CCTV
- Port used for accessing CCTV
