Hello,

A while back I had heard a technology and wanted to ask you guys.

In a hotel we would like to give internet access to the clients. We
have 8 switches connected to each other. What do I need to use in
order to take clients to the internet regardless of their Ip
addresses. The technology I am looking for is built in nomadix
appliences but I do not know what it is.

For example clients has 192.168.0.2 gw 192.168.0.1 configured. He
comes and connects his cable to the network. Our network is
172.168.0.0. Switch is 172.168.0.1 and the internet router is
172.168.0.2. And he can connect to internet with his own ip without
even needing dhcp?

I hope I was able to describe it properly.

Thank you.

The question is probably more appropriate in comp.protocols.tcp-ip, but
yes. You could use a DHCP server to give clients an IP address to use
while connected to your network. And you can also provide Mobile IP
services, by installing a "foreign agent" in your network. This permits
clients with permanent IP addresses to pretend like they're still
connected to their home network. RFC 2002.

In the usual case you would want a separate wire to the router
for each such connection, but it might be possible without that.

Unlike most networks, the hosts on your net won't (usually) need
to talk to each other. As more than one might have the same
address, that would complicate the usual IP routing situation.

I believe if you implement the logic of a NAT router for each
port, though not necessarily separate physical routers, it
can work. Each host will have to be identified by its
MAC address, and the data processed accordingly. This should
be a relatively simple change to the usual NAT router logic
for someone who really understands NAT and IP.
