When the router is deployed in DNS proxy mode, you specify a list of port and destination mappings. A destination may be either an IP address or a DNS name.
An egress router pod supports the following formats for specifying port and destination mappings:
- Port and remote address
You can specify a source port and a destination host by using the two field format:
The host can be an IP address or a DNS name. If a DNS name is provided, DNS resolution occurs at runtime. For a given host, the proxy connects to the specified source port on the destination host when connecting to the destination host IP address.
Port and remote address pair example
- Port, remote address, and remote port
You can specify a source port, a destination host, and a destination port by using the three field format:
<port> <remote_address> <remote_port>.
The three field format behaves identically to the two field version, with the exception that the destination port can be different than the source port.
