I'm looking for an IP router ("gateway" in old fashioned IP networking
terminology) to do IP routing between two ethernet interfaces.
To illustrate, imagine I have one network which has IP addresses
10.1.3.0/24 and another network with range 10.1.4.0/24, and I want a
device that simply sits between these (occupying 10.1.3.1 and 10.1.4.1
as an example) and routes IP packets according to nothing other than
knowledge of these two networks.
A PC can do this easily, but I want a cheap hardware device because of
the circumstances it is to be used in.
I can get a device that does this BUT forces the use of NAT for 30 UK
pounds, but NAT is not suitable for my needs. The world is full of
such NAT routers it seems. My understanding of IP networking makes me
think that, if it occured to the manufactures to offer the option,
turning off the NAT and doing basic IP routing should be easy.
Do such devices exist without buying a very expensive general purpose
Cisco router, complete with IOS?

Thanks for the prompt response. To answer your specific question, my
example required only one interface on each network. The device you
describe has those two interfaces and also a built-in hub or switch,
which is simply a bonus.
Having read the sections of the manual, and other material about this
router, it's clear that NAT can be disabled. It turns out we've even
got one of these little things in our company, and it can switch
between "router" and "gateway" mode.
This is exactly the type, functionality and price of product I was
looking for. Thank you.
