can't access proxmox web gui

hi,

this is my situation

i have a server with 2 lan cards
i use proxmox 2.2
i use ip public at lan card-1 (vmbr0 bridged to eth0) and local ip at lan card-2 (vmbr1 bridged to eth1)

the problem is :
i can access proxmox web gui from local ip (ssh worked) but i can't access proxmox web gui from ip public (and ssh is not worked).

i try to create VM and add my (another) ip public (same ip class) and i can access it from ip public.

looking forward for your resposes
