Could be a use case for X-Windows with ssh -X [0]? (so your web browser is actually running outside the GFW, it's just the window updates that are coming over the SSH tunnel).
any ssh traffic that does not look like ssh traffic (few bytes send to server, some more bytes returned) gets either terminated or slowed down to a crawl
Does this mean that in addition of the classic fail2ban, geoip firewall, or forever super slow login banners, we could also have a honey pot sending a lot of data with a traffic pattern similar than web browsing ?
