RB450G PPPOE server and forwarding of public IP to lan user

Hello,

I have strange situation.
on my rb 450g (router with pppoe server) on lan1 i have pool of public IP. Idea is to forward those public IP to some of Lan users (pppoe clients).
I’m using v4.5.
Server PPPoE is working on bridge (lan2, lan3, lan4 , lan5). and if i’m using connection withour redirect of public ip lan user has access to internet.
if a’m giving public ip to the user internet connection is missing

problem is that on x86 (intel) version with the same configuration this redirection is working perfectly.

could you help me?
