Question Cant access a website by direct modem connection but not through switch. Help?

FrankRunnerDrebin · May 16, 2024

We have an institution website that requires offices to register their IP addresses so as to login and work. We registered 5 IPs and are able to login to that website. But our modem has only 1 working port. So we used a switch and tried connecting, but that causes an invalid license error by that website. We are not shown the login page. The IPs and other things are the same. We can access everything else but somehow that website think we aren't a registered user. How is that happening? I don't know much about networking. Help please

What’s the model of the modem?

TEJAS TJ2100N-11G. It does not have wifi support. I think ours is a customized one as it says in their web page. Here: https://www.tejasnetworks.com/product/tj2100n-gpon-xgs-pon-ont.php
There is not much to do with the modem. I can access other websites fine. But this website gives us problem just because we are not connecting directly to the modem. How does it recognize there is a switch??

Ok, it only has one working port - please explain.

This device also looks to be a router as well. How is the device configured?

What is the model of the switch you're connecting.

As @ch33zw1z suggested, you could be using a router, not a switch.

yea, it kinda sounds like the ONT device is set to passthru, and plugging in a single device is working as expected, but a switch won't expand that. he'll need a router behind it. But that means the website will only see one IP (easier config on the website side anyways, lol)

Since My institution isn't cool with posting screenshot of its page, I will type its message here:
""license key violation. domain not matched"". This means that website (lets say xyz.com) thinks that I am connecting to it from an unregistered IP address, it says I am not licensed to connect to it.
But I can login to the website while directly connecting to the router/modem with the same IP, mask, gateway etc.
We are not allowed to make any modifications to the configuration of the router/modem.

Ok, it only has one working port - please explain. // The ISP set it that way. Its a government based free connection so we aren't allowed to modify that. We can only access this website (lets say xyz.com) through that ISP.

This device also looks to be a router as well. How is the device configured? // We don't know. They won't let us modify it.

What is the model of the switch you're connecting // I used 2 switches one is a Dlink DES 1008c.

Basically it means that I cannot do anything about the ISP or the router/modem. The only way is to figure out how the website xyz.com knows I am using a switch to connect to it. Maybe it gets the information from my PC? Otherwise how is it able to see my registered IP when It can only see the router's IP? (so i was told)

So

website -- TEJAS TJ2100N-11G -- PC then it works fine
website -- TEJAS TJ2100N-11G -- switch -- PC then you get license error?

ch33zw1z · May 17, 2024

Ok, so get an ipconfig /all for each scenario and post it here.

What kind of website register by IP? Are you saying each user is identified as a public ip? or is this an intranet site?
