也可以尝试传递本地绑定地址参数。最好明确说明远程端口映射到哪个本地端口

self.server=sshtunnel.SSHTunnelForwarder(
                    ('abc.int.net', 22),
                    ssh_username="sshuser",
                    ssh_password="sshpassword",
                    remote_bind_address=('remote.address.host', 4040),
                    local_bind_address=('127.0.0.1', 3331)
                    )
