Hello,

Is there special syntax required to use a variable name instead of hard-coding the interface name in a declaration like the following?

chain blackhole {
  type filter hook ingress device $external_interface priority -500; policy accept

Error: syntax error, unexpected '$', expecting string or quoted string or string with a trailing asterisk                 type filter hook ingress device $external_interface priority -500; policy accept

using the interface name directly instead of the variable works.
Try chain blackhole "{
  type filter hook ingress device $external_interface priority -500; policy accept }"


Trying the new syntax that allows using a list, 'ingress devices = { }' also fails when using a variable either inside an anonymous list, or as the name of a named list.


I am using nftables 9.3 from Debian Buster backports.
