That exclamation-mark is not interpreted; it just becomes part
of the string, with the expansion result, being tested by the
"condition" option.

The latter is documented as:
"if the result is [...] one of the strings “0” or “no” or “false”
(checked without regard to the case of the letters), the router is skipped.

So: forget the "!", and just have your lookup returning {0} or {1}.
Put them in *that* order in the ${lookup...} so that your condition
has the truth sense you wanted.


(You were assuming the rules for an ACL condition apply to a router
condition. Sorry. but historical reasons...)
