Tento estabelecer uma conexão SSH remota.
Tentei conectar "Remoto" comssh -fN -R 10110:localhost:22 GatewayUser@GatewayHost
e "Gateway" comssh -p10110 RemoteUser@localhost
Recebi a resposta no Gateway ConsoleConnection closed by ::1
executando-o com -vssh -v -fN -R 10110:localhost:22 GatewayUser@GatewayHost
produz essa resposta no console remoto

PS: uma conexão SSH do Remote para o Gateway está funcionando
Muito obrigado antecipadamente!

O que você faz é: Criar uma conexão ssh do raspi para o gateway e encaminhar *:10110 do gateway para 127.0.0.1:22 no raspi. Então você se conecta à porta 10110@localhost, que pode em algumas configurações usar o endereço ip6 (::1) que não possui túnel atrás dele. sshd então fecha a conexão. Tentar
ssh -4 -p10110 pi@localhost
Isso deve levar você um passo adiante. Se você tiver problemas para encontrar a chave correta (o ssh para após uma certa quantidade de chaves verificadas), desative pubkeyauth com
ssh -oPubkeyAuthentication=no -4 -p10110 pi@localhost

Seu ssh
cliente parece se conectar ao seu sshd
via IPv6. Escuta sshd
endereços IPv6? Adicione esta linha /etc/ssh/sshd_config
e reinicie sshd
:
ListenAddress ::
Ou você pode forçar a conexão IPv4 com ssh -4
argumento.
