Port Forwarding / Re: Need help with Port forwarding, TCP not open
« Last post by trpted on Today at 08:50:56 AM »
Let us do this step by step. Starting off with pre-checks.

* Pre-check item one  *

#1 Most ISP have a TOS ( Terms Of Service )

#2 You need to find that TOS for your ISP.

#3 If your ISP does not say anything that you can not to run any servers of any kind - green light.

#4 If your ISP does not allow you to run any servers of any kind - yellow light.

-> Be sure to know the risk of running any kind of server.

-> You have to decide is worth the risk or not, based upon...

a) ..how easy you can get another ISP to serve you - for example.

b) ..how much does it cost to upgrade the type of account that you have with your ISP. Example from regular consumer to gaming or business plan.

********************** Pre-check item two  **********************

#1 Go to http://ipv4.whatismyv6.com/

#2 On that web page is the non bogan IPv4 (Public) Address that users from Internet use to connect to you.

#3 In your router, somewhere in there you must have the same non bogan IP Address.

Example non bogan IP Address is 999.888.777.666, but in the router the WAN IP is 10.0.0.100 - this is not ok.

#4 Important note: This is not to say that the non bogan IP Address has to be Static.

Example yesterday's IP Address was 999.888.777.666 and today's IP Address is 999.888.777.555 - this is ok.

#5 If you do not see the non bogan IP Address anywhere in the your router it's screens, it first matters what the WAN IP Address in the router is:

a) From 100.64.0.0 - 100.127.255.255, then CGNAT/NAT444/LSN is present.

If you want more details about CGNAT/NAT444/LSN, you can look at

http://en.wikipedia.org/wiki/Carrier-grade_NAT

The possible fixes to fix your issue if CGNAT/NAT444/LSN is present.

#1 Have them in their NAT router forward the ports to the WAN IP of your router..

#2 Upgrading the type of plan that you are on with your ISP so that you get a non bogan IP Address.

For example if you are a Residential Service Plan, consider going to a Business Service Plan.

#3 Consider switching to another ISP that can give you you a non bogan IP Address.

#4 For the long term future, get IPv6 working.


<<<

b) From 10.0.0.0 to 10.255.255.255, from 172.16.0.0 to 172.31.255.255 OR from 192.168.0.0 to 192.168.255.255 and if NAT router is a RJ-45 WAN port router:

Step 1: Physically find your NAT Router

Step 2: Find the WAN port of it.

Info: WAN port could be called Internet or To Modem or To ONT port.

Step 3: Report back what the brand and model of the device that is connected at the other end of the wire that is connected to the WAN port of the NAT router.

c) If from 10.0.0.0 to 10.255.255.255, from 172.16.0.0 to 172.31.255.255 OR from 192.168.0.0 to 192.168.255.255 and if your NAT router is a gateway NAT router, it matters how it is connected to the Internet (RJ-45 WAN port or acting a modem combo).

d) If the WAN IP was not any of those, it would be a good idea to check to see how the non bogan IP Address is not the same (and not NAT). If you need help finding why that is, you are to asking for help doing so.

-> Since you post what brand and model of your router is, it is a modem combo

************* Pre-check item three  ***************

As how to check what the IP Address is/are, Subnet Mask is/are, Default Gateway is, MAC Address(es) is/are, DNS Server(s) are of your computer, it depends on the OS and Version.

Note: This example assumes that you are on Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10

#1 Press the Windows Start key to open the Start screen.

#2 Type cmd and press Enter to launch the command prompt.

Note: You do not need to click on anything on the Start screen—typing will automatically initiate a program search.

#3 Type ipconfig /allat the command prompt to check the network card settings.

#4 If not on Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10 and you do not know how to check that network info - then post what is your OS and Version is.

#5 You need to make sure that the Default Gateway on your computer is the same LAN IP as your NAT router.

*** Done with Pre-checks, doing to the next the step. ****

#1 When you forwarded you forwarded to the LAN IP of your computer?

For example assuming that the Default Gateway on your computer is the same as the NAT router's LAN IP Address and if you get this output

IP Address 192.168.1.10
Subnet Mask 255.255.255.0
Default Gateway 192.168.1.1
At least one DNS 192.168.1.1

-> you would forward to 192.168.1.10

#2 If all of this info does not open the port, I will tell what the next step(s) is/are.

Lorex Auto Port Forwarding / Re: HELP NEEDED - Port Forwarding IP Question
« Last post by trpted on September 15, 2017, 12:44:55 PM »
#1 You use both.

#2 To be more exact:

a) You use the Internal one as the one to forward to as well as to connect to when behind your NAT router.

b) You use the External one as the one you need to connect to when not behind your NAT router.

Lorex Auto Port Forwarding / HELP NEEDED - Port Forwarding IP Question
« Last post by Lana on September 13, 2017, 06:49:10 PM »
Hello -
I have a new router that the lorex program is finally recognizing (Yay it made the router DB!).  I'm setting up port forwarding on the router.  IPv4.  I have 2 options, External IP address or Internal IP address...which one do I enter/use?  Internal?

Thanks,
Alana

Unknown as to why, since I am not support for that program.

News flash: Your modem is a not a modem combo.

Just realized that even though I enter my serial into the program, still says I need Pro version. Curious to know why that is happening. Also, I have spare computers but I don't think have a PC setup for making it into a Nat Router. I have a wireless router and a modem, my modem is bought to work compatible with TWC/Spectrum. Not much options in the menu to make any changes to it.

By looking at your last thread that you started ( http://forums.pcwintech.com/index.php/topic,5792.0.html ) you have your own RJ-45 WAN port router behind your modem (TechniColor TC8717T).

If you still have a RJ-45 WAN port router behind the modem (Arris SB6183), then:

#1 Make sure that all of your computers are behind your RJ-45 WAN port router.

#2 Your RJ-45 WAN port router can hardware based (for example the Linksys E4200 v1) or software based (Examples that are listed at that DSLR news thing posted back on Tuesday Mar 20 2012 at 16:14 EST: m0n0wall, pfSense, Smoothwall, Untangle, and Astaro Security Gateway - direct URL REF https://www.dslreports.com/shownews/118897 ).

#3 If you have( or had ) a spare computer that is not in use that works that either has:

a) Two NICs (and note at least one must be a wired NIC)

b) OR you can add a second NIC into the computer (For example by a second NIC into the computer I mean a PCI NIC like the TRENDnet - Fast Ethernet PCI Adapter (Model: TE100-PCIWN)  )

...then you could covert that spare computer that works into acting a NAT router.

#4 Note: If want to use a spare computer as a NAT Router, before connecting it to the modem combo that is in bridge mode: Be sure to know which NIC is which - as the NIC will not be ( LAN VS the WAN/ Internet / To Modem / To ONT - port ) labeled!

#5 Some other info about building / turning a computer into acting as a NAT router, besides that DSLR news thing,

https://www.dslreports.com/forum/r30568002-Numbers-don-t-lie-it-s-time-to-build-your-own-router

https://www.dslreports.com/forum/r30984220-The-Router-rumble-Ars-DIY-build-faces-better-tests-tougher-competition

#6 In the RJ-45 WAN port router, forward the ports that you need to.

**

-> OR if the ISP does not want to help you put the modem combo into bridge mode / OR if it does not stay in bridge mode, since you are on Cable:

#1 Get a cable modem that is not a cable modem combo, that has a web based UI (or Telnet OR ftp or SNMP - that does not require for special program)

By special program, I mean for example For Windows - http://www.dslreports.com/faq/16899 (For Unix/Linux like see http://adslm.dohrenburg.net/linux/linux.php )

For example of a cable modem that is not a cable modem combo, that has a web based UI (or Telnet OR ftp or SNMP) is the Motorola SB6141.

#2 If you have a telephony too: If possible get and use two modems, like what I have.

One just for telephony (in my case Arris TM602G/115) and the other just for Internet (in my case the Motorola SB6141 with my own RJ-45 WAN port router behind it).

Since I do not use the same ISP (Service Electric/PTD) that you do, make sure that your ISP allows this.
