Hi, guys!
After moving proxing from ajp to http (as ajp is not supported officially by ORDS) we got an IP of proxy not real client in apex_workspace_sessions.remote_addr as APEX seems to get OWA_UTIL.GET_CGI_ENV('REMOTE_ADDR')) but not
OWA_UTIL.GET_CGI_ENV('X-FORWARDED-FOR').
I guess ORDS's settings can change it to log real clients ip (X-FORWARDED-FOR)
Appreciate for Your ideas.
