SSH Tunnel with SSHFS to bypass balabit restriction

Tunnel ssh/balabit

Client

1. mount the remote filesystem with sshfs

$ sshfs sshremote_server:/tmp /tmp/remote_dir

2. mock your webserver with netcat and redirect request to the file /request
and response to the  file response

$ while true; do
    nc -l 8080  < /tmp/remote_dir/response  | cat > /tmp/pastaremota/request;
done

3. Unmount the filesystem
fusermount -u /tmp/remote_dir

Server behind balabit

Wait for input in file request with tail and redirect to the real webserver using netcat

$ while true; do
    tail -f /tmp/request | nc localhost 10010 > /tmp/response;
done
