Guest Miha Posted September 18, 2007 Posted September 18, 2007 Hi Have a problem with setting one of two Ethernet adapters to default. Win2003 Web Server, 2 NICs are connected to a switch which has two firewalls connected to it. 1 NIC 190.191.0.18/16 GW 190.191.2.1 2 NIC 190.191.0.17/16 GW 190.191.0.1 First NIC routes through a firewall that has access to the internet, second NIC routers through a firewall that has access to LAN and Internet. But after restarting server, or disabling/enabling second NIC, default traffic is always routed through second NIC through GW 190.191.0.1, but I want that internet traffic is always routed through the first NIC that has GW 190.191.2.1? So in other words I want to achieve that first NIC will be default adapter. How can this be done? Thank you in advance Regards,Miha

Guest Bill Grant Posted September 18, 2007 Posted September 18, 2007 Re: How to set NIC to be default You should not have two NICs enabled which are in the same IP subnet, unless they are teamed. You can only have one gateway per machine, not one per interface.

Guest Claus Posted September 19, 2007 Posted September 19, 2007 Re: How to set NIC to be default What is the purpose for this unsupported configuration? It doesn't make much sense. And why are you using a class B network mask? If you want it to work you need to create a routing table on your server and tell it which addresses to use with which interface. In order to do that you first need to define the traffic that you want to see over the 0.17 interface. What is the subnet range that you want to use via 0.17? After you have done that, you send the rest through 0.18. -- Claus "Miha" <miha.bernik@email.si> wrote in message news:uQQgTDk%23HHA.4880@TK2MSFTNGP03.phx.gbl... > Hi > > > > Have a problem with setting one of two Ethernet adapters to default. > > Win2003 Web Server, 2 NICs are connected to a switch which has two > firewalls connected to it. > > > > 1 NIC 190.191.0.18/16 GW 190.191.2.1 > > 2 NIC 190.191.0.17/16 GW 190.191.0.1 > > > > First NIC routes through a firewall that has access to the internet, > second NIC routers through a firewall that has access to LAN and Internet. > > But after restarting server, or disabling/enabling second NIC, default > traffic is always routed through second NIC through GW 190.191.0.1, but I > want that internet traffic is always routed through the first NIC that has > GW 190.191.2.1? > > So in other words I want to achieve that first NIC will be default > adapter. > > How can this be done? > > Thank you in advance > > > > Regards,Miha > >
Guest Miha Posted September 19, 2007 Posted September 19, 2007 Re: How to set NIC to be default Yes that was the problem. I deleted gw on the second nic and now it works like we wanted. Thanks!
