DHCP relay is not working FW 5100 and smb 1550

Hi

I've set up DHCP relay according to this SK 

Configuring DHCP relay through Site-to-Site VPN on GAIA embedded Appliances (checkpoint.com)

but it is not working, is something else has to be set up ?

FW 5100 80.30 , SMB 1550 80.20

The 5100 needs rules to let DHCP server behind it communicate thru VPN tunnel. You should see the drops in logs or using fw ctl zdebug + drop.

subnet where the DHCP server is placed is a part of VPN traffic, ANY / ANY traffic is allowed within VPN subnets
