wanarp.sys and LLInterface

NTDEV
1

Hello all,

I’m looking for information on how to implements my own arp module
that will replace the default arp module, like wanarp.sys in dial-up
connection.

Any help would be appreciated,
Guy

As far as I know the interface between tcpip.sys and ARP modules is
undocumented. Standard way how to filter packets or change their contents is
NDIS IM or filter driver. For what reason do you need custom ARP module?

I’m writing a miniport driver that emulates Ethernet over InfiniBand
fabric.

I can filter the arp packets, but I think that the “right way” to do it
is by creating an arp module.

Thanks,
Guy

I don’t think so. If your miniport emulates Ethernet, it should behave
exactly as Ethernet on its upper side. There can be several filters between
your miniport and ARP layer which would be consused if part of processing is
done in ARP module. Anyway, custom ARP modules aren’t documented and
supported.

To run TCP/IP over some “interesting” network media, you can
either a) emulate Ethernet over it fully OR b) write a custom ARP
(undocumented).
MS uses custom ARPs for PPP and for 1394 (since IP over 1394 is
RFCed and does not imply Ethernet emulation). MS’s ATM support can use
both modes - ARP and LANE.

IIRC ARP module not only resolves the addresses, but also governs
what IP routing table entries will be added to describe this
interface.

Thanks a lot.

I think I’ll take Vodicka’s advice (option a in your reply).
