Is there a command that does the same thing as a Cisco ip helper-address on the fortinet?

    The ip helper-address interface subcommand tells the router to forward UDP broadcasts, including BootP, received on this interface. (UDP is the connectionless alternative to TCP at the Transport Layer.) Use the ip helper-address interface subcommand to specify the destination address for forwarding broadcast packets.
    .... refer from Cisco website~ I don' t think so... instead you could setup the firewall policy to allow the UDP traffic passing through the Interface if you do need the UDP broadcast anyway.........

    But what the helper address does is specify a particular ip address to forward that request to.

    Look under DHCP and configure a relay.

    Does that work for things other than DHCP thou?

    All I' ve ever used an ip helper-address for is DHCP relaying, and that' s all this would solve. Since, apparently, that command can forward mutliple traffic types then the DHCP configuration would not be your solution.

    Yeah I' m sure that' s the most common use of it. However it does forward all udp broadcasts to the specified ip (which certainly can be helpful in unique situations).

    Seems like there are some problems with DHCP-relay and MR5; I have 16 sites which all of them was running DHCP-relay against a DHCP-server (W2K3) in main office and everyone was happy. After installation of MR5 (both 0547 and 0559); DHCP-relayed stopped working. Support got a report about this. . Yngve
