Hide Server IP

hello, i used cloudflare to hide my hosting IP
but any one can get my ip easy

go to www.mysite.com:2087 and try to login with any wrong user and pas
then he will get this msg
This is admin area!!!
*> Login to NEW User Panel <*

and if he click on (Login to NEW User Panel) he will get url like this (ip:2083)
how i can fix it

Why, are you making the next SilkRoad or AlphaBay? (In that case, don't use CWP!)
