From the perspective of Firebird, the Citrix machine **is** the client.
The fact that the user remotes into the Citrix machine makes no
difference to Firebird, as the Citrix machine is what makes the actual
connection.

So, no there is nothing built-in in Firebird to do this automatically
(and I don't think there never will be). If you want something like
that, your application needs to take care of that itself (eg by setting
a variable in the USER_SESSION context).

For example, your application will need to obtain the client IP address
in some way (I don't know Citrix, so I don't know if and how that can be
done), then after connect, it needs to execute:

select RDB$SET_CONTEXT('USER_SESSION', 'CITRIX_CLIENT_IP', '<the ip
address>') from RDB$DATABASE

Subsequently, other parts of your application can get this using

select RDB$GET_CONTEXT('USER_SESSION', 'CITRIX_CLIENT_IP') from RDB$DATABASE
