Installation and Upgrades / multiple static IP over pppoe

« on: April 17, 2009, 08:15:54 pm »

Hi all

I received several static IP addresses from my ISP.
Because I'll be running several different Web Servers I need to forward the external IP to the virtual and other computers and they have to communicate with this external IP.

When dialling with pppoe I receive the static IP. e.g. 80.80.80.80
The ISP has given me 8 additional IPs. e.g. 79.79.79.1 - 79.79.79.8

How can I forward the additional static IPs to the virtual machines and eth1?

My system looks like this:

      -------------------
      | pppoe modem |
      -------------------
                 |
       (eth0) |
      ------------------
      | Ubuntu eBox |  80.80.80.80 (pppoe)
      ------------------
       (eth1) |     |                                 -------------------------------
                 |     +------------------------| Virtual PC on Ubuntu eBox | 79.79.79.2, 79.79.79.3, 79.79.79.4
                 |                                       -------------------------------
                 |
         ----------
        | Switch |
         ----------
                 |
                 |                                ----------------
                 +------------------------| Webserver 1 | 79.79.79.5
                 |                                ----------------
                 |
                 |                                 ----------------
                 +------------------------| Webserver 2 | 79.79.79.6
                 |                                 ----------------
                 |
                 |                    ---------------                  -----------------
                 +--------------| Router NAT | ----------- | Workstation 1 | 192.168.1.1
                                      ---------------                  -----------------
                                    ( 79.79.79.7 / 192.168.1.100)

Many thanks for your answers!

Installation and Upgrades / NAT for multiple IPs

« on: October 15, 2008, 06:16:39 pm »

Hi all

I read about ebox and searched the manual but still have a question regarding IP forwarding in a LAN:

I have a ADSL connection with several static external IP addresses.
The computer I want to use has one NIC and several virtual machines with static IPs that should be available through a external IP.

The ADSL router can forward all incomming traffic on a specific port to a specific IP.
E.g.
All external IPs:22 --> 192.168.1.100:22
All external IPs:443 --> 192.168.1.100:443

Is it possible with the above configuration to forward to a internal IP according to the external IP?
So that if a connections comes into the ADSL router on IP 78.31.123.100 that ebox forwards this to 10.0.0.100 and if a connection comes into the ADSL router on IP 43.42.189.234 that ebox forwards this to 10.0.0.200?

If this is not possible what hardware do I need to forward to internal IPs?

Many thanks for your ideas and support!

Edit:
My setup looks like this:

+-----------+
 | Internet |
+-+--------+
     |
     | Multiple IP's
+-+--------------+
 | DSL Modem |
+-+--------------+
     |
     | 192.168.1.100
+-+-------+
 | ebox    |
+-+--+--+
     |    |
     |   +-----------+
     |                     |
+-+-------+   +-+-------+
| Server1 |     | Server2 |
+----------+   +-----------+
10.0.0.100    10.0.0.200
