We have several AS/400 connected to each other through DRDA and they work fine, but we can't make the Informix server visible to AS/400.

Tell me, please:
Is it possible to obtain data from Informix to AS/400 through DRDA?
i.e. Informix will be DRDA-server and AS/400 will be DRDA-client. (Reverse way is possible and is not interesting to us.)

If it is possible then what we need to do on both sides?
(Do we need to install something on Informix side?)
