[AusNOG] DHCP/PXE Packets between multiple VLAN on Vyatta

[Craig Askings]

It will be something like this example. eth1 / eth3 are the interfaces where it is watching for dhcp / PXE discovery requests and server is the ip of the dhcp server it will relay it to.

service {
    dhcp-relay {
        interface eth3
        interface eth1
        server 192.168.2.5
    }
}
