Is a bridge the way to go from ppoe to a lan if you have multiple public IP's?

What I was wondering if a bridge is the right way to go.  Here is the situation:

I have a dsl connectin with 5 static ip's assigned to me from the dsl company.  I want to use each of these ip's on different computers on my network some of them going to other subnets through various ways such as wingate, and ipmasq.

My first thought was to use ipmasq, as I was already familur with setting this up.  As I soon realized I could not use the static IP's from the ISP with this solution.

Now I am researching putting up a linux bridge. Using Linux to connect through ppoe through eth0 and the hub on eth1 where my computers that need the static public ip's are.

Not sure exactly what you are trying to achieve, but the conventional way to do this is:


INTERNET
 |
 |
 |
ROUTER (ADSL/Cable/Serial interface)
 |
 |       (Everything above here is the red zone)
 |
FIREWALL/ROUTER  (Possibly your linux bridge?)
 |                    |
 |                    +--------------->PC1     PC2     PC3     PC4    PC5    (The orange zone)
 |
 |
Internal network (The green zone)


The area outside of your firewall is known as the red zone (very low level security - low security). The orange zone is configured using the firewall to be accessable from the internet, and also from the green zone.  The green zone is configured using the firewall so that external access is not possible.


PCs in the orange zone tend to include web servers/ftp servers/mail , and other resources.
PCs in the green zone are normally the internal office and user PCs.

Using this configuration, you'd apply the fixed IPs that you have been given to the PCs in the orange zone, and then if you required them to be a gateway to another network, you would configure the network PC allocated the fixed IP as another firewall/router, and port forward if you required access to a specific resource inside of the network.



Bridging is if you require to link 2 networks together to form a single network. An example is:



USA half of network----ethernet-->PC1(Bridge)--------ISDN/FIBRE/CABLE etc------->PC2(Bridge)--ethernet-->UK half



Basically the 2 bridging PCs provide a transparent interface to the network, in much the same way as your modem/phone line provides a transparent interface to the internet using a dial up connection using PPPoE.

Hope that helps clarify things:)

Well if that is the way I am going to have to do it.
What I was really looking for is a way to not a have a router and have the linux box sign in to the isp on the dsl.
Thanks for your input...I guess its time to get that router.

You can get cards that provide the ADSL interface, however, due to the trouble with support from most ISP suppliers with anything non-standard...i.e - they won't support it at all, the best way IMHO is to keep the 2 bits seperate - better still use the recommended router from the supplier...and just work with an ethernet link to the outside world - takes all the hassle out of the configuration and support of the system (well most of it :)  )
