SSH tunnels using PuTTY

Networking
1

I’m currently having problems with OpenVPN and I would like to troubleshoot remotely. I can connect to the firewall using SSH and in the past I used SSH TCP tunnels to connect to the web interface remotely. PuTTY is version 0.78 on Windows 10 (1909).

I believe I have set the SSH Access option Allow TCP Forwarding but can I verify that setting from the SSH command line? If so, how?

Does this output mean the option is not set?

Apr 11 12:43:24 wscfw sshd[31774]: refused local port forward: originator 0.0.0.0 port 0, target 192.168.10.1 port 444
Apr 11 12:43:24 wscfw last message repeated 3 times

Assuming that option is set, in PuTTY I have the tunnels set as follows:

Is this the correct syntax?

the Default port for Ipfire is 222 for SSH.
if you have not changed it?

I surrendered and make a road trip… The SSH Access option Allow TCP Forwarding was NOT checked. Checking that option was all that was necessary.

hopefully the traffic is not bad and the weather nice.

what a coincidence:

sshd-session[19457]:	refused local port forward: originator 0.0.0.0 port 0, target 192.168.0.1 port 80

unfortunately the checkbox Allow TCP forwarding is :white_check_mark:
inside sshd_config

# Do not allow any kind of forwarding (provides only low security);
# some of them might need to be re-enabled if SSH server is a jump platform
AllowTcpForwarding yes
AllowAgentForwarding no
PermitOpen any
