  • 2 NIC on server and their IP range

    I have 2 NIC on my server.The 1st NIC is connected to switch and provide my LAN connection.
    The 2nd NIC is a DVB PCI card which provide my internet connection throw one way satelite connection.
    ISA04 is running on win03.I have not activated windows RRAS.MY 1st NIC IP is
    10.20.20.1-subnet mask 255.0.0.0.
    I do not know the range I should use for my 2nd NIC(DVB card).
    How these 2 NIC communicate with each other?should I use any rule on ISA?
    Any Practical Solution for this situation?

    Since it's your internet connection why not ask your ISP?

      dear danielp,
      Since I don't think ISP has any responsibility about my internal Network.Simple rule: You connected to their network and recieve data then they have done accord to their agreements

      I don't think that's a strange problem,but need your help to do it.My problem is that I have 2NIC on 1 server thses 2 connected to different Networks.I do not Use Windows Routing Console and Use ISA as NAT for My internal Network.What should be the TCP/IP settings of the 2nd NIC to communicate with My Internal Network.
      bet regards,

        Your internal card (DVB) needs to talk to your router/modem so it shuold be on the same subnet.

          First of all, please contact the server vendor. Sometimes, advanced vendors like HP allow you to create a virtual network adapter so the server use 1 IP and use two pysical adapter (This require supported switch - Manage switch - HP/Nortel/Cisco will do the work).
          Also, using two nics (without the virtual NIC) on the same server cancreate problems like:

              This is basics m8.

              The IP address of both NIC's will be in the same corresponding network are the router

              Nic#2

              IP Address:- Should be in the same range as the DSL router.
              SNM:- Should be in the same range as the DSL router.
              Default Gateway:- Should be the IP Address of the internal interface of DSL router.

              Your ISP should provide you with these details.

              NIC#3

              IP Address:- Should be in the same range as the satellite router.
              SNM:- Should be in the same range as the satellite router.
              Default Gateway:- Should be the IP Address of the internal interface of satellite router.

              Your ISP should provide you with these details

                dear wullieb1,
                I have set these settings before but my problem still continuing.Dvb is one way satelite connection.I use DSL Line as my send connection and dVB as recieve.Therefore I connect throw VPN connection to satelite internet connection so that I could Recieve throw Satelite provider connection.therefore NO IP to set for DVB(NIC#3).
                My most problem is with ISA.
                My DSL modem works in brige mode.it's an ethernet modem and I have connected it to my 2nd NIC on server.It does not have any Valid IP.It's a PPPoE connection.
                I have set 192.168.0.0-192.168.0.250 as the internal in ISA2004.
                It block my Satelite Traffic.I do not know whther I should add my DVB as internal In ISA or not.

                  Re: 2 NIC on server and their IP range

                  Now i'm confused.

                  To be on the internet you NEED an IP address no matter what.

                  Is your DSL static or dynamic?? How is it connceted to the server?? USB or NIC??

                  I've never dealt with satellite before but you will still need and IP address to get to the internet.

                  Maybe one of the more ISA orientated guy's can help.

                    DSL modem Is connected to server throw cat5e cable.

                    The 3rd NIC duty is just recive.if you do not use firewall Like ISA,then you could use it without any TCP/IP settings.When It works onlt Packets recieved.To enable this qualification you should use VPN to satelite connection provider.

                      "Network and Routing Issues
                      This section describes network and routing issues and solutions.

                      ISA Server Does Not Support Multiple External Interfaces
                      Problem: ISA Server does not support multiple external connections to
                      the Internet.

                      Cause: ISA Server does not support configuring multiple connections on
                      the External network adapter.

                      Solution: No workaround. There are a number of third-party products
                      that may provide a solution. For more information, see High
                      Availability and Load Balancing at the Windows Server System Web
                      site."

                      this is taken from an ISA list.. by a Microsoft Bloke ISA server doesn't support 2 External Interfaces. There is an issue in routing traffic through multiple interfaces as there is only one gateway

                          thanks for you comments simonwhale,Dumber

                          I have tried different configurations even I have added persistent route in my server to route packets from NIC#3 to local host but it does not answer.I concluded that ISA Block the NIC#3 Traffic therefore I could not use that.
                          I think according to above text ISA blocks the NIC traffic sinceIt's not able to support the additional external interface.
