Captive portal prevents web access to directly connected web server

RouterOS General
1

Hello Anyone,

My network diagram is very simple as per attached.
Problem is that 192.168.1.1 user can not get web access to web site that is hosted on 192.168.2.1.
User can ping to server IP 192.169.2.1.
Server can ping to User IP 192.168.1.1.
User 192.168.1.1 is under captive portal.

Please let me know some tweaks that solve this issue.

Regards,
