Hi folks,
	Is this group for what I think it's for, i.e. demon
subscribers who are developing TCP/IP products?

	I'm the primary author of PsiStack, the freeware TCP/IP stack
for Psion Series 3 handheld computers... see
http://www.gumbley.demon.co.uk/psistack.html for more details... 

	The problem I have is this: the stack has no concept of
routing (to keep things as simple and small as possible). The
data-link layer is SLIP, with PPP to be added later. At the moment,
the decision to send a datagram over the SLIP link is done by
comparing the network ID of the IP address of the SLIP interface, and
that of the destination. If they match, the datagram is sent. If they
don't match, how do I send the datagram to a gateway - where does the
gateway's IP address go? Certainly not in the IP header's destination
address... or do I just send the datagram over the SLIP link,
addressed to the eventual destination, and expect the gateway to see a
datagram destined for another network, and so route it accordingly?

	If you're interested in this project, please get in touch - we
need all the help we can get! (PPP experts especially!)

	Regards,
		Matt
