    Hi All,

    I have installed a second nic card into my server it is running ubuntu 8.10 and ispconfig 2.x,

    When I enabled the the second card, we are unable to connect to the server via http or smtp. I have not changed any config files yet ?

    Just to add, I have install VMware Server and ISPConfig 3.x on a VM, I am wanting to use the 2nd nic on the VM, curerntly my router forwards all ISPConfig traffic to NIC1, I have "or will give" NIC2 an IP which I can slowly migrate domain to the new ISPCONFIG server and direct the traffic to that IP.

    Just a little more explination

    The server1 has 2 nic's

    It is sitting behind router2 which is plugged into router1 which is connected to a thrid internet router with 5 ip's

    Internet router IP x.x.x.25 (LAN SIDE)
    Router1 - WAN x.x.x.27 & LAN 10.10.0.1
    Router2 - WAN 10.10.0.2 & LAN 192.168.1.1
    eth0 192.168.1.250

    I want to migrate to ISPConfig3 on a VM on the server1
    I want to setup eth1 with IP x.x.x.26 so that it's internet facing and then I can slowly change DNS to point to the new IP as I mirgate the domains and sites.

    Another options is to use apache and somehow mail routing. but this I don't know how to do either.
    The VM ca use eth0 or eth1 for traffic. so which ever is easier as this is temp till the migration is complete.

    I understands this but how do I configure it that if traffic comes in on eth0 it should also got out on eth0 and the same for eth1 ?

    I would also like to know the answer to this question. I am having a similar problem with 2 NIC's. In my case though it appears only the LAN gateway shows and not a the real WAN gateway IP.
