Reverse Proxy Firewall Configuration

Note: If you have a local firewall on your proxy server (such as iptables), verify that it is not blocking the SSH and FASP transfer ports.

External Firewall: The TCP and UDP ports on which the internal server is listening must be allowed. By default, these are TCP and UDP/33001.

Internal Firewall: The TCP and UDP ports on which the internal server is listening must be allowed, but only for connections originating from the proxy server.. By default, the ports are TCP and UDP/33001.

Note: If proxy_port has been set to a value other than 33001, or has been set to a range to accommodate load balancing or UDP port reuse, then that port or range of ports must be allowed through the external and internal firewalls. For more information on port configuration for load balancing, see Load Balancing. For more information on port configuration for UDP port reuse, see UDP Port Reuse.
