What IP to set on primary router if the one in my secondary is 192.168.1.X

Hi,

First of all, my current plan from my ISP offers internet + phone on and gave us a router that has a phone port. But since the router is terrible, I decided to get my own router that I setup between the modem and my ISP's router (I should also mention that I have no control over my ISP's router because they don't want use to reset it or give us the password). Once I got my router working I could connect to the internet and all and then connected an ethernet port on the LAN of my router that goes into the WAN of my ISP's router. Fortunately the phone does work, I can receive and send calls but it randomly hangs up after a couple of seconds of talk or maximum 5 minutes. I red somewhere that the problem could be the firewall and so I disabled:

PPTP PASSTHROUGH
L2TP PASSTHROUGH
IPSEC PASSTHROUGH
FTP ALG
TFTP ALG
H323 ALG
RTSP ALG
SIP ALG

just to make sure that it works and it still doesn't. My ISP's network IP 192.168.1.X and when I put the same on my router the phone did not work. I am out of ideas on what to do and it sucks that I can't even configure my ISP's router.

I would also like to mention that my previous router's IP was 192.168.0.X and now I set it to 192.168.2.X which I doubt would do anything.

Thanks.

Ok so you have a cable modem.
And from the cable modem you connect it to the router where you should have an Ethernet port listed on the back of it that says WAN.

Then you should have four other ports on the router that are for setup of your network, or for a wired network.


The external IP of the cable modem is sent to the router, also known as the Gateway address.
Where when logging into the first router you should see the wan address setup of the cable modem.

The 192.168.1.0

IP address you see in the router is the local area network IP pool.

That starts off as 192.168.1.0 that being the router address.

Any IP out of the 192.168.1.x pool can be selected or used for any computer connected to the router.

Where as an example the first connected computer will be given an IP of 192.168.1.1 up to 253 for the end number or X as you put it. So 192.168.1.1 to 192.168.1.253. max amount of computers connected.



If you add a second router it will be assigned a IP address of 192.168.1. X 1-253.

Where anything connected to the second router and its Ethernet ports will also fall into the 192.168.1.X IP pool.

ALG is used for Voip configuration, so if the Modem, or router has this option.

It means like you said you will have a RJ 11 type connector to plug a phone into the router or modem.
So it uses Voip protocols for phone over a network.

If for the second router as you said you set 192.168.2.X.

Then you have created a sub part of the network where the two routers are connected.

That means the second router will have to do Network translation.

Where the default wan or address needs to be in the range of the first router and it`s Ip address range.
In other words for the Wan the IP should be 192.168.1.3 ect.


Say for example you connect a computer to the second router.

It will be given an IP address of 192.168.2.X X= .1 to 253.

Then you open a web browser ect and request a web page say google.

It will go from your machine of 192.168.2.5 to 192.168.2.0 from the second router to the first router. Of 192.168.1.0
Then to the external Wan IP, or the internet connection of the first router.
When the web page is found it is sent in the reverse order.

So Wan IP of the first router to the internal IP address pool setup on the first router.

Where it then translates to 192.168.2.0 of the second router setup.
And finally to the Second routers IP pool setup of 192.168.2.5
The 192.168.2.5 IP the second router gave the computer or client connected to the second router.

Hope it`s not to complex.

Basically if you connected three routers the third internal ip pool would be setup as 192.168.3.0
The wan address would be set as 192.168.2.0
The you have created a network with three routers that can each handle up to a maximum of 253 client computer systems connected to each router and they can all have internet access via the first router.

Thank you for taking the time to reply back, but the second router that you mention is my ISP's router in which I have no control over and the primary one is mine. I set my router (primary as 192.168.2.1) while the ISP's router (secondary as 192.162.1.254) and disabled all the ALG firewalls but it still hangs up in the middle of a call.

*UPDATE*: The call does not hang up when I call someone but when I receive one it hangs up after like 30 seconds. It's really annoying and I don't want to return to my ISP's router because it's garbage and struggles to keep a stable connection for the house.

*UPDATE 2*: I have contacted TP-LINK customer support (my router's brand) and they helped me instead. The reason is that the data had to go through 2 NATs. So I added my ISP's router that was connected to my router into something called DMZ. I also set a static IP for my ISP's router with the mac address so that it never changes.
