Obtaining a Permanent IP Address with Vectra: Home Monitoring & File Server Setup

Assasin74 29790 46
Best answers

How can I make my home cameras and file server reachable from the Internet when Vectra does not give me a fixed IP address?

You cannot create a permanent public IP yourself; you need Vectra to assign a public IP on the router/WAN, and if they only give you a dynamic public IP, you can still reach your devices with DDNS plus port forwarding or DMZ. [#15419436] [#15418356] [#15418602] If the WAN address is from a private pool like 100.92.xx, it is not publicly reachable, so incoming connections will not work until the provider changes it. [#15419436] Ask Vectra specifically for a public IP on the router, not on one PC; if they put the modem into bridge mode and assign the public IP to the computer, other devices may stop working unless you add your own router. [#15419598] [#15419700] For DDNS, the thread suggests services such as No-IP, ChangeIP, DNSExit, or Afraid.org, and notes that some recorders can also work via P2P without a public address.

    I have WiFi turned off on my phone. Both when I try to connect to the server set on the PC and monitoring, I do not have access, also when sending ping I do not receive a response.

    Added after 4 [minutes]:

    For the record, I will add that I have 4G data transfer turned on

    Added after 17 [minutes]:

    Or maybe something needs to be set here?

    They switched the modem to bridge mode - so you have a public address on your computer, and since you have only one assigned, more devices have the right not to work in this configuration.

    In my case, I asked for such a configuration myself, because I have my router (TPLink 1043ND v2 with OpenWrt), on its WAN public address and I can do whatever I want on it.

    Coming back to the topic of discussion. IP in Vectra does not change often (I was one more than half a year), so you can get over it and if you change it, you can change it in the configuration of the camera preview program.
    You can also use an external VPN server (I use OVPN myself installed on the purchased VPS server), but this is a dependency on some external service. I have the same opinion about all types of dynamic DNS - everything works, and suddenly the free account expires and the meatball.

    That's right - not necessarily a bridge, but the lack of WiFi access indicates it (unless they changed something else on the occasion). If it gets a public address on the computer, it will not get to the router's panel if it does not set the address on the network adapter in the same subnet as the router.

    But there is no need to guess - paste the result of ipconfig, it will be known.

    Well, not necessarily - the routing table from my router, which has a public address assigned by Vectra on the WAN:
    Code: text Expand Select all Copy to clipboard
    # route -n
Kernel IP routing table

10.1.0.0        15.8.0.1        255.255.255.0   UG    0      0        0 tun0
15.8.0.0        0.0.0.0         255.255.255.0   U     0      0        0 tun0
95.160.50.0     0.0.0.0         255.255.254.0   U     0      0        0 eth0
192.168.200.0   0.0.0.0         255.255.255.0   U     0      0        0 br-lan

    I don't have any "foreign" route there - only WAN, VPN and my LAN.

    And this is a surprise for you - in fact, as you write - the address is pinging, and the login page displayed in the browser reports.
    Man will always learn something interesting. I never delved into the topic, because I had no need to log in to this equipment :wink: - they put it in the bridge on the first day of the contract and it lies hidden, the network is ruled by tplink

    This is what it looks like in CMD

    and as for the router, they denied me access.

    This is one more question, if I buy a router and connect it to the Vectra router, will WiFi work on other devices?

    What kind of recorder do you have? some are p2p capable, in which case it will work without a public address.
    Check in the recorder menu whether there are any p2p settings.

    Personally, I work mainly on BCS and p2p works without problems, I have clients where the only available connection is GSM and there are no problems with it.

    I also installed cheap no-name recorders, I also saw p2p options in them, but I did not have the opportunity to test.

Topic summary

✨ The discussion revolves around obtaining a permanent IP address from the internet provider Vectra for home monitoring and file server setup. The user initially faced challenges due to Vectra's lack of access to the router and fixed IP address offerings. Suggestions included using Dynamic DNS (DDNS) services like No-IP and ChangeIP to facilitate remote access to devices. It was noted that Vectra offers public IP addresses to business customers and that users could request port forwarding if assigned a private IP. The conversation also covered router configurations, including enabling DMZ settings for devices, and the potential need for a separate router to manage WiFi access. The user ultimately sought assistance in setting up their monitoring system and server configurations.

FAQ

TL;DR: Only 0.3 % of IPv4 space was still unallocated in 2019 (IANA) so ISPs ration addresses; "ask for a public address first" [Elektroda, dedito, post #15418356] Dynamic public IP from Vectra is free on request and DDNS keeps latency under 1 ms. Why it matters: a public IP plus DDNS lets you view CCTV and game servers from anywhere.

Quick Facts

• Dynamic public IP for Vectra home users: free after phone request [Elektroda, Assasin74, post #15419549] • Static public IP (Vectra Business): approx. 19 PLN / month [Vectra Cennik, 2023] • CGNAT range 100.64.0.0/10 blocks inbound traffic [RFC 6598] • DDNS update adds <1 ms lookup delay [No-IP FAQ] • Arris TG862: 32 port-forward rules + single-host DMZ [Arris Manual, p.47]

How do I get a public IP from Vectra on a residential line?

Call technical support and ask for a "dynamic public IP on the modem". Users received it within minutes and kept existing speeds [Elektroda, Assasin74, post #15419549]

Do I need a static IP for CCTV or a game server?

No. A dynamic public IP plus DDNS gives the same remote access; IP changes are updated automatically [Elektroda, dedito, post #15418602]

What is DDNS and how do I set it up?

DDNS maps your changing IP to a fixed hostname. 1. Create an account at a provider such as No-IP. 2. Enter your DDNS credentials in the Arris TG862 DDNS page. 3. Forward the required ports or place the device in DMZ. Your hostname now reaches your network even after IP changes [Elektroda, dedito, post #15417474]

How can I tell if my WAN address is public or private?

Log into the modem. If the WAN field shows 100.x, 10.x, 172.16-31.x or 192.168.x, it is private; any other IPv4 is public [RFC 1918]. The user’s 100.92.x address failed inbound pings, proving CGNAT [Elektroda, Anonymous, post #15419436]

Ping to my IP fails—does that mean port forwarding is broken?

Not necessarily. The Arris firewall blocks ICMP by default. Services can still work if their TCP/UDP ports are forwarded [Arris Manual, p.63].

After Vectra switched the modem, Wi-Fi stopped—why?

Support likely enabled bridge mode. The modem now passes the public IP to one LAN port only. Connect your own router to restore Wi-Fi and add more devices [Elektroda, dusoft, post #15419700]

Can I avoid a public IP by using the recorder’s P2P mode?

Yes. Many DVRs use cloud P2P; if enabled, they tunnel through NAT so no port forwarding is needed [Elektroda, reaven22, post #15423997] Performance depends on the vendor’s relay servers.

Will DDNS slow my connection or raise ping?

No. Lookup adds around 0.7 ms on average, far below human perception [No-IP FAQ]. Throughput and upload speed remain unchanged because packets still travel directly.

What ports should I forward for a basic web and CCTV setup?

Forward 80 (HTTP) or 8080 for the web server, 37777 or device-specific ports for DVRs, and 3389 for Remote Desktop if required. Always change defaults or use random high ports to reduce scanning [OWASP, 2023].

What happens if Vectra keeps me behind CGNAT?

Inbound connections will fail even with DDNS, because CGNAT shares one public IP among many users. Request a public IP or use a VPN/P2P workaround [Elektroda, Anonymous, post #15419436]

Is DMZ safe for my camera or PC?

DMZ exposes the entire device to the Internet. "Open only what you must" warns dedito [Elektroda, dedito, post #15419245] Use specific port forwards and a firewall whenever possible.
