DHCP Relay is not working?

Hi,
I’m trying to use DHCP Relay, but it doesn’t work.

Config is simple (I try a lot of options…):

Relay:
/ip dhcp-relay add dhcp-server=10.0.1.1 disabled=no interface=bridge1 local-address=10.0.1.2 name=relay1
/ip address add address=10.0.1.2/24 interface=bridge1 network=10.0.1.0

Server (With IP 10.0.1.1):
/ip dhcp-server add address-pool=dhcp_pool2 authoritative=after-2sec-delay bootp-support=static disabled=no interface=bridge_datos lease-time=10m name=server3 relay=10.0.1.2
/ip dhcp-server network add address=10.0.1.0/24 comment=“default configuration” dhcp-option=“” dns-server=10.0.1.1 gateway=10.0.1.1 ntp-server=“” wins-server=“”
/ip pool add name=dhcp_pool2 ranges=10.0.1.10-10.0.1.249


Relay client log shows:
echo: dhcp,debug,packet relay1 sending discover with id 1071010659 to 10.0.1.1
echo: dhcp,debug,packet hops = 1
echo: dhcp,debug,packet flags = broadcast
echo: dhcp,debug,packet ciaddr = 0.0.0.0
echo: dhcp,debug,packet giaddr = 10.0.1.2
echo: dhcp,debug,packet chaddr = 00:26:22:39:BE:75
echo: dhcp,debug,packet Msg-Type = discover
echo: dhcp,debug,packet Client-Id = 01-00-26-22-39-BE-75
echo: dhcp,debug,packet Address-Request = 10.0.0.136
echo: dhcp,debug,packet Host-Name = “PC Client PC”
echo: dhcp,debug,packet Class-Id = “MSFT 5.0”
echo: dhcp,debug,packet Parameter-List = Subnet-Mask,Domain-Name,Router,Domain-Server,NETBIOS-Name-Server,NETBIOS-Node-Type,NETBIOS-Scope,Router-Discovery,Static-Route,Classless-Route,MS-Classless-Route,Vendor-Specific

And Server only show:
echo: dhcp,debug received discover from 00:26:22:39:BE:75 with unknown giaddr 0.0.0.0

Client PC never can’t take a new IP
(If I delete Relay IP from DHCP Server, then all works fine, but I need use Relay IP for subnets assigment)

Can someone help me??
Thanks
