all the branches are forwarded, but probably they are discarded as the
additional ones are looped back. Check your config and be sure you allow
traffic from "scr_ip==mysqlf" without authentication.

The alternative is to use lookup_branches() instead of lookup() -- see
the readme of registrar module.
