DHCP between router and firewall

[gabelz]

HI all,

i've DCHP server configured on FW eth1/4 and static IP on router interface Gi0/0.

Which configuration i should apply to ROUTER-EDGE in order that PC4 could receive IP address from FW DHCP server?

Thanks in advance,

MG

you should use helper address

Hi Kasun,

thanks for reply.I did already and not working:

FW port eth 1/4 ip address 2.2.2.2/24

DHCP server conf on FW

on EDGE-ROUTER:

interface GigabitEthernet0/2
no ip address
ip helper-address 2.2.2.2
duplex auto
speed auto
media-type rj45

Gateway of last resort is 2.2.2.2 to network 0.0.0.0

S* 0.0.0.0/0 [254/0] via 2.2.2.2
2.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 2.2.2.0/24 is directly connected, GigabitEthernet0/0
L 2.2.2.50/32 is directly connected, GigabitEthernet0/0

on PC4> ip dhcp
DDD
Can't find dhcp server

Thanks,

MG
