How to put LAN to use public IPs without bridge?

rz8168 · Thu Jun 17, 2004 1:29 am

I'm currently using bridges say..
interface "public" and interface "local" are on bridge1

they work flawlessly but I encounter one problem which is bandwidth limitation. I couldn't get it to work with bridge using PCQ. My question is, is there any other way to let local network to use public ip address? I've tried ARP-PROXY but it didn't work. Please help.

Need more information on your setup. Is this bridge inbetween your gateway to the internet and your users?. Please be specific in what your network layout is and your ip address scheme.

<LAN> --> <MT> --> <CISCO Router> --> <DS3/internet>

I have 5 subnets of public ip addresses.

10.10.10.0/24
10.10.11.0/24
10.10.12.0/24
10.10.13.0/24
10.10.14.0/24

hello rz,

sorry to inform you, but 10.*.*.* addresses have never been and will never be public addresses.

In general, these IP ranges ARE NOT public and will not be public:

10.everything - 10.0.0.1 up to 10.255.255.255 (A subnet)
192.168.0.1 - 192.168.255.255 (B subnet)
172.16.0.0 - 172.31.255.255 (partial B)

bye, mp3turbo.

Our real public ip addresses start with 64.x.x.x and 208.x.x.x. I'm using 10.10.x.x as example, not our actual public ips.

Anyone? Or it's not possible?

I have public and private ip on my lan.

I set up proxy-arp on the public interface and assigned a public ip to my customers and also a public ip to the private interface. So the proxy-arp can join the two subnet.

I'm not a network gutu but it works like a charm.

bye

Why not use just throttle bandwidth by IP address? I started routing public addresses recently using a bridged interface and limiting bandwidth in this way is working very well for us.

So are you saying it would be better to use bridge and PCQ? I don't understand what do you mean by throttle bandwidth by IP address.. can you please explain in more detail? Thanks.

Why don't you simply route the public IPs (subnet) inside the LAN?

We are ISP for student housing, and we provide public internet access to internal and external as we promised to students.
