Routing public IP addresses through privale lan.
I am planning the following network design:
I have a network of DHCP servers (routers with a DHCP server really) hosted
on an private addressing space, this DHCP servers are going to assign
public IP addreses, so here comes my problem, how can I route this
addresses from the machine really connected to the internet downstream to
the corresponding private address of the router which will assign that IP
address?. The reason which I am using private addressing on dhcp servers is
that my addressing space is really limited (I guess as everybody) and using
external IP'addresses on routers would hace two problems, first is
insecurity and secondwaste of addressing space.
Any ideas on how to do this?. Does the "route-to" parameter help?¿.
Now my second problem is the following:
Suppose this routers & DHCP servers (same machine) are really wireless
access points which are going to assign public addresses to wireless
customers, what method I could use to update dinamic routes, I guess some
dinamic routing protocol (BGP?, RIP? or OSPF?) would help but dont really
know wich one, and my other problem is that my wireless access points do
not support this routing protocols, so I guess I would have to make some
weird things with an expect script to reconfigure those access points
through console access (I know it sounds kind of strange).
Thanks in advance.
