Quick interface question

I have 2 Ip Adresses coming from my ISP assigned by DHCP. I have my cable modem, eth0, and eth1 connected to a belkin switch. Both devices receive ip addresses. Although when both are enabled I am unable to access network resources of any kind. Beloiw is a rough diagram.

btw, I forgot to mention that I find it a bit funny that I am unable to assing a gateway for each interface.

Code:


     ----           ---

     |  |-----------| |  SWitch

     ----           ---

     Modem           |

                     |

                     |

                     |

                   Astaro

                ------------

                |          |

                |          |

              eth0        eth1

           66.69.*.*    66.69.*.*

Any help is greatly appreciated as I would like to use the ip on eth1 for server access.

You can (should) do this with one External NIC, and create a virtual nic for the second address.

Then, use SNAT to forward traffic as you wish.

Okay.. So I tried your suggestion using a VLAN and setting it to DHCP.. I get the following when trying to bring up the interface.

Code:

You cannot set up an interface of this type on the selected hardware, since it cannot coexist with another active device on the same hardware.

He said they're BOTH assigned by DHCP. I thought you couldn't have 2 DHCP assigned IPs on the same physical NIC?

Oops... sorry.

But can you have 2 nics on the same switch? I've had some problems when doing that before (with other Linux systems, not ASL).
