Lightweight DHCP Relay Agent with GIF tunnel support

A light-weight DHCP Relay Agent.

Why not the ISC DHCP Relay Agent?

  • If your RA has multiple interfaces, you get multiple requests for each request

    DHCPREQUEST for 10.199.14.216 from 0010dcd1e639 foo via 10.199.14.1 DHCPACK on 10.199.14.216 to 0010dcd1e639 foo via 10.199.14.1 DHCPREQUEST for 10.199.14.216 from 0010dcd1e639 foo via 10.10.3.5 wrong network. DHCPNAK on 10.199.14.216 to 0010dcd1e639 via 10.10.3.5

    This RA sends only one request, coming with the IP address of the LAN the request came from.

  • If your RA has multiple interfaces, the outgoing interfaces to the WAN needs to be active in the DHCP relay otherwise answers are not picked up.

    This RA uses a unicast socket for returning answers.

  • If your RA has non-ethernet interfaces GIF-tunnels for example, which VPN back to the central network, the answers are not picked up by the RA.
