I have SSH port forwarding set up on my Business Smart Hub 6, software rev SG4B1B008146. All looks good for a few seconds to minutes (variable), and then connections hang. This only happens when going via port forwarding on the Business Smart Hub. SSH to the same server, when accessed locally to the network, works fine.
Are there any known issues with port forwarding and SSH? I also have HTTPS port forwarding configured, and (so far) that has not been seen to fail.
