Thread: Dual Network Card in RH7.3

    Dual Network Card in RH7.3

    What i have now:

    I have 1 server with 2 network cards:

    NIC1
    - Static IP (219.93.225.x)
    - connects to a switch that gives me DSL connection

    NIC2
    - Internal IP (192.168.100.x)
    - connects to a switch to my LAN


    What i'm trying to achieve:

    1. Let my LAN users access the server internally
    2. Use the server to host my website


    I would like to map watever request from NIC2 to NIC1 so that watever request is processed transparently to the users.
    Since this is gona expose my LAN, i figured that i should have a firewall for security.
    Is there any software on RH7.3 that allows me to do this? If yes, how?
    Thanks in advance

    First of all, Welcome to LJR.

    Redhat 7.3 Bible by Christopher Negus gives a good run down on how to setup everything for the two NIC cards so you can do both. However, /10ded puts on security cap, You want to be really careful having a firewall, a webserver, and the gateway all on one computer. If a blackhat were to stumble onto your little lan, in short order you would find yourself up shit creek without the proverbial paddle.
    As for firewall's, if you browse thru the security section you will find several good firewalls that peeps recommend. I personally use Monmotha's, It starts automatically whenever I connect. But the choice is yours.

    IIRC Red Hat 7.3 used ipchains as the default firewall, so get a book on that. 10dedfish is absoultely correct on both points, the book he reccomends (Red Hat has good docs, but for printed in store shit -- this is where its at), and the NAT/Firewall/HTTPD box is not a great idea. Make the server spearate from your gateway. Just use forwarding to route the traffic, after its filtered of course.
