What service should a Prosody mod_proxy65 proxy offer?

I am adding the mod_proxy65 module to a Prosody server so that it is suitable for XMPP clients supporting XEP-0065. This allows file transfers between clients that are each behind a firewall (NAT).

Minimal configuration examples:

Component "proxy.example.com" "proxy65"

or

Component "proxy.example.com" "proxy65"
    proxy65_address = "example.com"
    proxy65_acl = { "example.com" }

The documentation (linked above) suggests that the mod_proxy65 component should point to "a bytestream proxy", but what does this mean, concretely? What is an example of a service I should install at the proxy.example.com endpoint?

Solution 1:

From the Prosody users mailing list, mod_proxy65 is itself the "bytestream proxy" service, and proxy.example.com is just a different DNS record pointing to the same Prosody server.

If you don't want to set up an additional DNS record, use proxy65_address to direct the client to the existing DNS record of your Prosody server.

See the mailing list message (above) and "File and image transfer" in Extra Modules for Prosody for more details.
