HELP: NON NAT HIGH SPEED MODEM ROUTERS

Hi

I have just bought a Belkin 125MB wireless modem router.

I have just found out that this router uses NAT. I now need help
finding high speed wireless modem routers that do not use NAT.

I have 5 external IP's which need to be related to internal IP's. This
is important as I have FTP and remote desktop sessions running
constantly.

Any recommendations?

Why is "nat" a problem ?

You won't find one.

I doubt if any are made for retail sale.

I don't know the Belkin, but most routers have ways of doing that.

Because of the way that many ADSL routers only handle the 1<->many
variant of NAT where a single public IP address (that of the WAN
interface) is NAT'd into multiple IP addresses on the LAN side. This
is inconvenient (to say the least) when you have a multiple IP address
block especially if you require access to more than one system on the
LAN from outside, as although many routers provide a DMZ capability it
can normally only contain a single system.

When you have multiple IP addresses allocated you either need a router
which does no NAT, and presents the global IP addresses on the LAN
interface or you need a router which does many<->many NAT (which not
many ADSL routers have) where you can map external IP addresses to
specific local IP addresses on the LAN.

Or you could (not suggesting this as best idea!) disable the NAT feature
on a (relatively cheap) ADSL modem/router and on the LAN side, plug in a
second (cheap) router (no ADSL modem) so the WAN side has one of many IP
addresses with LAN side handling any more PCs which need to be via NAT.

I'd have thought NAT could be disabled on whatever model Belkin this is,
so the original poster might consider this method, though the need for a
wireless model would make this less attractive, perhaps. Peter M.

If it's of any relevance Zyxel routers (well all the ones I have seen)
do many to many NAT.

.... or, as I said, a Zyxel.

I disabled NAT in my router (d-link) and could not connect to my isp, seemed
that the isp required it maybe?

Maybe then something like smoothwall on a old box then the wireless lan side
..
