Hi Aleks,

It's look to me that this is not possible.
To quote from Section 2.3 of configuration.txt:
Those variables are interpreted only within double quotes. Variables
are expanded during the configuration parsing. Variable names must be
preceded by a dollar ("$") and optionally enclosed with braces ("{}")
similarly to what is done in Bourne shell.
Thus, it should work once you enclose your bind values into double
quotes (without the potential linebreak added by my mail client):
bind ":${ROUTER_SERVICE_HTTP_PORT}"
"${ROUTER_SERVICE_HTTP_PORT_BIND_OPTONS}"
This will however prevent you from setting multiple (space-separated)
bind options as they will only be recognized as a single value due to
the quotes.
Thanks for answer.
Here the tests which I have done.

My conclusion is that with or without " the ${...} is not substituted,
at least in the bind line.
