Hi there, I am trying to setup a Raspberry Pi 3 behind our firewall but unable to see the device in the dash. I’m pretty certain its a firewall config issue but wanted to see if I was missing something obvious with the Resin config first.
We used to have a Watchguard firewall with (as far as Im aware) the same config in terms of NAT / open ports and this all worked fine. We now have a Cyberoam and the connection seems to be intermittent. Every now and then the device will show in the dash for a couple of minutes and then disappear again and the action light on the Pi will start showing the network connection error sequence.
We have NAT in place for HTTPS traffic as we have two services on two different servers here so the traffic is routed depending on the inbound IP to the appropriate box on the internal network. Ports are open for all outbound traffic. However the setup was the same on the Watchguard in terms of NAT etc so I’m struggling to understand why it no longer works on the new kit.
Any help appreciated.
