Hi, whenever I try to enter the ports 80 and 443 at the beginning of the -R parameter, I get this error: Warning: remote port forwarding failed for listen port 80
. How do I fix this?

How do I make the SSH tunnel forward traffic? It can't be as easy as just running ssh user@SERVER_IP
in the terminal.
(I only need variant 1 btw)
I've added the firewall rule and it still says no port[s] to connect to
whenever I run echo "Testing" | nc -u SERVER_IP -p 51820
. I feel like you're trying to stay on a sinking ship, so I would suggest to try another method to see if we even can get the whole "bypass CGNAT with a VPS" thing to work at all.
Update: I've tried setting up SSH tunneling instead and it STILL doesn't work. I contacted Hetzner support about this issue and I'm hoping that they can resolve the firewall issues that I'm having.
I've added some different ports for the future, but this is my ufw status
:
Status: active
To Action From
-- ------ ----
OpenSSH ALLOW Anywhere
51820 ALLOW Anywhere
2333 ALLOW Anywhere
80 ALLOW Anywhere
81 ALLOW Anywhere
443 ALLOW Anywhere
80/tcp ALLOW Anywhere
OpenSSH (v6) ALLOW Anywhere (v6)

80 (v6) ALLOW Anywhere (v6)
81 (v6) ALLOW Anywhere (v6)
443 (v6) ALLOW Anywhere (v6)

Alright, I switched to ufw
and... it's still not working. sigh
Should we just try something completely different? WireGuard doesn't seem to be working on my VPS. Someone in the comments mentioned tunneling via SSH, sounds interesting.
What do you mean with "clear out iptables completely"? Should I remove the iptables package with sudo apt remove iptables
?
Alright, sounds good. What firewall are you recommending me to use? I would like to use a firewall that's easy to manage.
Edit: I went with ufw
.
I tried to open the port 22 on UDP (yeah, I am getting pretty desperate over here...) and still get the message no port[s] to connect to
... Someone else on this post commented that I should stop using iptables for opening ports and start using something else as a firewall. Should I try this approach?
Does iptables count as a firewall? You said that I should "forget" iptables. Is it that bad? It came preinstalled on the VPS. Should I switch? And if so, how?
Very interesting... How do I get started?
The command you provided for the VPS returns UDP listen needs -p arg
, so I just added -p
right before the port number and then it worked. Running the homelab command returns no port[s] to connect to
... Not good.
Why did ZippyBot bring me here?
