Reverse Proxy firewall configuration

In the following sections, you can find the information to configure the Reverse Proxy firewall.

External firewall

The TCP and UDP ports on which the internal server is listening must be allowed. By default, these are TCP/22 and UDP/33001.

Internal firewall

The TCP and UDP ports on which the internal server is listening must be allowed, but only for connections that originate from the proxy server. By default, the ports are TCP/22 and UDP/33001.

Note: If proxy_port was set to a value other than 33001, or was 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.
