Is there any layer 3 device between client and dhcp server? Then you need dhcp relay agent,if that is not the case chk firewall. Thanks

Hi all,
i've just installed a FreeRadius server 2.2.0 with DHCP support because i need a dhcp server that use MySQL ad a backend.
My network topology is:
eth0 inet addr:193.205.4.xxx [PUBLIC] eth1 inet addr:172.20.1.2 [PRIVATE]
all dhcp requests and reply should come from eth1. Here is freeradius -X dump:
