I don't see any DHCP packets received in the debug.
If I put the R1 also in the same vlan as vlan 3 and set the IP of R1 fa0/0 to the vlan 3 subnet IP, It is serving IP address to R3.
I know it is difficult to troubleshoot to someone else's config on the e-mail.
I just want to make the IOS DHCP server to server IP for remote subnets. If anyone have any working config, I will test it.

What does debug for DHCP on R1 looks like ?
