Port Forwarding

[erezson]

Hello everybody,

Sorry that I'm writing in English but my German is not the best.

I have Hitron CVE-30360 as modem (wlan disabled by KD) and private Asus router.
I have Raspberry Pi with SSH enabled, so I opened a port forwarding (22) in the Asus router - which allow me to connect it as long as I'm part of the Router connections.

When I try to login the Raspberry Pi by using the ISP IP - I can't. It doesn't even see the port open.
So I did the following:
* Added Host Port (22) on Hitron that points to the Router - Didn't work!
* Connected the Raspberry Pi directly to the Hitron modem and added Host Port to the Raspberry Pi directly - didn't work!

it seems like the Hitron blocks the connection from outside.
Anyone has an idea what could be the problem?

Thank you in Advance!!

The Hitron is a router as well - and as long as you have not enabled the BridgeMode within the "Kundencenter", it will act as router (and also do NAT).
The best is to enable the BridgeMode within the "Kundencenter" in order to get a public IPv4 on your ASUS router.

Otherwise, it might be that your Hitron router uses DualStack Lite, so it does NOT have a public IPv4 address. The [public] IPv4 address that you may see using services like "wie-ist-meine-ip.de" is a shared IPv4 address that multiple customers are using.

Thanks a lot for your help!

Can I do it via the Kunden portal? (because I can't find it)
Or I need to call them?
