| 619613 | 2007-12-09 23:16:00 | Hi all. I have a Asus A8N-E motherboard with a 10/100 NIC integrated, plus a PCI TP-Link wireless NIC. The thing I try to go over is: set one NIC as the main one I use for surfing internet; while as another I'd like it to be used as connecting in the LAN. Statically, I assigned IPs for both of these NICs. Details r as followed: Motherboard integrated NIC: IP: 192.168.1.11 Mask: 255.255.255.0 Default Gateway: 192.168.1.1 DNS: 192.168.1.1 Wireless NIC: IP: 192.168.1.10 Mask: 255.255.255.0 Default Gateway: N/A DNS: N/A Problems I am having are: 1. When people from other PCs in the LAN type in & run "\\192.168.1.11", they can still see and access my stuff. But I want them can only access my files thru 192.168.1.10, but NOT 192.168.1.11 at all. 2. Sometimes when my computer s rebooted into the system (Vista Business 64bit), it appears that the wireless NIC is taking time to try to identify its default gateway, and at the same time there is no info filled in the motherboard NIC at all. If I try to again manually fill in IP, default gateway and so on to re-tell the system - USE THIS NIC TO GO TO THE INTERNET, NOT THE WIRELESS ONE! when I clicked “OK” it just keeps complaining "Warning - Multiple default gateways are intended to provide redundancy to a single network......" However, I have only 1 default gateway through, there is none filled in the default gateway part in the wireless NIC, how cum... At this point, the only thing I could do to fix it is, reboot & reboot, until the system randomly chooses the motherboard NIC as the go-to-internet one. Sorry for the unreadable description. Any help would be appreciated!! Thanks in advance！ |

| 619615 | 2007-12-09 23:33:00 | not sure if it would work or not. but you could use a different ip range or subnet for the LAN. that should clear up any confusion maybe. as they will essentially be 2 different networks not able to access each other. which means the other pc's will have to change ip range's and subnets as well to be able to access the wireless NIC. i may be wrong. but im sure someone else will point that out :D |

| 619616 | 2007-12-09 23:38:00 | I know my original mind could be very puerile. Because my flatmate often access to my drive for watching movies, copying things, and some other stuff. I just want to give them a NIC particularly doing those things rather than sharing a NIC I use to surf internet. I doubt my internet speed could be affected. So I give one NIC the default gateway but no to the other. I actually have tried to also give the motherboard NIC the diff subnet mask, but this could only deny the others in the LAN to access my files thru the motherboard NIC, but it is not helpful to stop the warning msg of multiple default gateway stuff. |

| 619617 | 2007-12-09 23:44:00 | other option is to get the gateway on both nics. that may stop it from being annoying and telling you that each one's default gateway is different. that way it may solve that problem. and they can not access the net on the wireless NIC because you won't have Internet sharing enabled. but then if they are all plugged into the modem/router as well then it wont make much of a difference anyway. |

Do you mean even my true default gateway is 192.168.1.1, but just fill in sth wrong like 192.168.100.1 into the NIC property? |

| 619619 | 2007-12-10 04:53:00 | no i mean give both nics your proper gateway address. just because it knows where the gateway is does not mean it can be used by others for net traffic. although your pc might try to use both for net access. Don't know much about this. just suggestions :D. maybe someone else can confirm or rebut my idea. |

| 619620 | 2007-12-10 05:58:00 | sorry but i still duno wot to do exactly. I dont want to let it everything go automatically by DHCP, because as long as I have a stable & static IP, others in the subnet can easily explore and access files from my pc. From your suggestion, which reminds me another question which I have ever asked somewhere b4 but still with no reply yet - Is there any application I can use to appoint traffic? Especially in the cases of having more than one NIC. For example, I could let all traffic caused by IE all go thru NIC 1. At the same time, appoint all local LAN traffic go thru NIC 2. |

| 619621 | 2007-12-10 08:05:00 | Could you not simply set up your firewall so that it blocks remotely-initiated access to your 192.168.1.11 address? It should still let that NIC initiate any connections. That's pretty much what all firewall software does anyway - just not sure if it would let you do it on one address that would normally be in your "trusted" subnet. | MushHead (10626) | ||
| 619622 | 2007-12-11 00:42:00 | I think it will work best if you make your interfaces live in different subnets. Try 192.168.1.x and 192.168.2.x . | Graham L (2) | ||
