Dual Nics For Accessing Network And Dedicated NAS?
Nov 24, 2011
I'm trying to setup a server with two nics, one of which is connected to the network, and the other connected to a NAS via crossover. I've never done anything with subnetting, but I was thinking I could just set the main nic to 192.168.10.20 with a subnet of 255.255.255.0 and the other to 192.168.10.250 with a subnet of 255.255.255.240 and the nas nic set to 192.168.10.251
Am I thinking through this right, or is there a better way to do this?

Ok so even though this isn't really needed, it's for a 10 user office I have two tower servers with dual nics but not the same brand (just bought a cheapy gigabit startech) to go with intel on board nic. Also my switch is also gigabit which is a trendnet teg-s24dg which does not support link aggregration.
But since I have two nics and both servers are running win2008 enterprise I want to use the other nics for throughput if possible. So to give an idea servers are doing DC/AD and fileserver DFS rep. If I turn one off the other picks up and network still functions (there is a small lag since dns has to pick up that other is not responding. So far the best I can think I can do with the extra nic is add ip's to second nics and add to dns and round robin or install NLB role to for two server cluster.
I can't really team them since they are two different brands, so what would you do or do you suggest I can do with them. Also I have a T1 and dsl going into a dual wan firewall dsl is not being used for anything. (might use it for a seperate wifi network if people need it.

Does Cisco MSE 3350 comes with two NICs. I want to configure them as a team bound to one IP address and send each to a separate 6509 switchport all in the name of redundancy and failover.

Our current topology is a single N7K with two 48port 10Gb F2 linecards and FEX 2224TP in the server racks. In a few of the racks that house important servers, we have placed dual FEX 2224's. Each FEX has 2 10Gb links back to the N7k (each link on a separate LC). I've tried to create a port-channel for the important servers in such a way that each NIC on the server is connected to a separate FEX - but its failing (simple drawing attached). I've read multiple posts saying this is possible, and others that say its not. I've also submitted a TAC case and have been told it's impossible to port-channel interfaces on separate FEXs connected to a single N7k - but I find this an impossible limitation and want to verify it's actually right. Is this really a limitation?

I have a networked PC with 2 NICs.One is connected to our business network, with a static IP address (10.38.75.xx) the other NIC (10.42.10.xx) is connected to a Controller machine.The business side of things works fine - network access & internet access works well.The intent with this PC is for a vendor to be able to RDP it (which he can) then open a browser and use the Controller's IP address (10.42.10.33) to access and control the connected machine.I am an administrator - logged in as myself, and trying to browse to this IP address, the page tries to load forever. It never times out or displays an error - just continues trying to load.At first, the vendor that was accessing this machine, when logged in as himself, COULD get the web page to open up at that IP - but he wasn't authorized to install an activeX program that needed to be installed. Logged in as myself, I couldn't get to the point where it asked to install the program.
Because I couldn't figure out how to fix this, I just set him as a local administrator as a short term fix - now he can't access the web page either. I've tried setting him back (removing his adminstrator privileges) - but now neither of us are able to access this page.

In my restaurant, we currently have a password protected wifi network for customers and staff. The load is typically light, so it's worked fine. Now, we're putting in a new cloud-based point of sales system, which effectively means that I need a totally uninterrupted, high quality wireless signal running to the POS terminal (in this case, an iPad). If the terminal is sharing that connection with 15 customers Facebooking on their iPhones, I imagine we'll have some signal issues. I'd rather not install a second network dedicated to the POS terminal. Are there any other possible solutions, i.e. a way to give priority to the terminal over other connections? A way to "split" the existing network so only a portion of it is available to customers?
FYI, current network speed is 20/mbs 2/mbs, and the POS terminal requires a minimum of 7/2 mbs.

I'm considering adding a dedicated Firewall to my network.Here is what my home network currently consists of:
-Comcast Arris TM722 Broadband Modem
-Netgear WNDR4500 N900 Gigabit WiFi 450/450 Router
-2 x Netgear GS108NA 8 Port Gigabit Switches
-1 x Netgear WN2500RP Universal WiFi Range Extender
-4 Pc's running Windows 7 Home Premium
-Netgear ReadyNAS NV+
-3 x Blu-ray players - Sony & Oppo (2 wired, 1 connected by WiFi)
-Sony PS3 (wired)
-Onkyo TX-NR905 AVR (wired)
-Sony KDL-55HX800 TV (wired)
-2 x Vizio E400 Seies Smart TV's (1 wired, 1 connected by WiFi through Netgear WN2500RP Range Extender)
-HP Photosmart Printer
All wired connections using Cat6 ethernet cabling.So, I want to setup a Gigabit Firewall between the modem and the router (and just use the router as the wireless access point) but I don't want to take a hit on my bandwidth speed.I was thinking of the Netgear ProSafe FVS318G for this.

I know enough to be dangerous when it comes to networking, but this one has me baffled. I'm running a win 7 pc with dual nics.
I need to have 1 nic connected to a vpn and the other to be restricted to intranet access only. I can't for the life of me figure out how to accomplish this.
Once I connect 1 nic to the VPN i'm no longer visible to my lan, even if the 2nd nic is connected.

I am wondering if all routers that have a USB port to which network storage can be attached, support the functionality to enable that storage to be accessed from outside the network. If this is true how (in a conceptual sense) can the router be configured to do this and what are the security implications?

I am connecting the router to a corporate network that assigns "real" IP to it (DHCP). Then I have 3 computers connecting to this router (local IP 192.168.1.2-4).Assuming I want to access a network drive named "ADrive" (on the same corporate LAN) from any of those 3 PCs, how do I do it? ("\ADrive" does not work, neither does replacing the network drive name with its IP, cannot ping either - it's like I'm on a totally separate network).

Q1/ I have 2 WinXP laptops on the network. One is WinXP Pro and one is WinXP HomeIn My Network Places of WinXP Home, it can see the WinXP Pro. In WinXP Pro, I have to do a search of the WinXP Home computer in order to detect its existence. WhyQ2/ In both systems, when I tried to access the other computer, a popup screen asked for password. I keyed in the proper password, but I cannot access the computer on the network. I repeatedly keying in the password but had the same result. I turned off the firewall on both systems. Same problem existed. On both systems, "File and Printer Sharing" are enabled in the Firewall exception. And on both systems, I can ping the other system without any problem

Setup as follows:
Cisco ASA 5510
Inside 172.17.101.249
outside 5.5.5.2
DMZ 192.168.100.1
I have an internal server 172.16.1.202 that is PAT to 5.5.5.103 to allow RDP connections. - This works fine from the internet.I have now been asked to allow our guest wireless (192.168.100.0/24 - DMZ) to access this same external connection.We have 2 cisco controllers, with the guest controller "anchored" in the DMZ.I cannot get this to work.Both the DMZ and inside NAT their internet connections to 5.5.5.2.

have a home network and access it thru an ATT wireless router. I also have a wireless printer but unable to access it vis the network. I ran ipconfig. I can see ip address for the router, ie, the Ethernet adapter wireless network connections: IP add, Submask, Default, DHCP Class Id. I also see 'Media State....Media Disconnected' Could this affect not having access to the wireless printer?

How do I block a particular IP from accessing my network entirely? I have a hacker with a known IP I want to shut out. I tried creating a DENY inbound filter (with just that IP as the range) but that didn't seem to work. that hacker kept being able to attempt logins.

Is there any way to access the router's configuration pages (192.168.0.1) via the Guest wireless network when routing between the zones is disabled?
Here's the story:
I am using my landlords wireless internet, but I administer the router myself. The router is 'upstairs' and i am 'downstairs' and he has his computer plugged into it plus one wireless laptop. He knows nothing about computers and is vulnerable to downloading viruses (and other ****) and I don't want my computers to be on the same 'network' as his.
I had a brilliant idea that since I am 100% wireless, I can make a guest network, put all my computers on that network and disable routing between them. Now all of my computers (some connected through a wireless bridge) can not see his computers at all (perfect!). The only problem now is I can no longer access the router config pages at 192.168.0.1!
Is there any way I can segregate my computers from his and also access the router config? I've tried accessing the WAN IP for the remote admin pages from inside the NAT, but it still blocks it.

Just upgraded my system. I am using D-Link 615 as access point hardwired LAN to LAN to ActiveTec MI424WR N capable Verizon Fios Wireless Modem/Router. The Fios Router is set up with WPA2 security. Intend on having three 615s as Access Points off of ActiveTec. Have a number of wireless devices accessing the network. Have followed instructions from manual to use 615 as Access Point, disabling UPnP and the DNCP Server function on the 615. My ActiveTec IP address is 192.168.1.1 and I changed the 615 to 192.168.1.50. I can type this IP address in my browser and get to the 615 set-up.
I have tried a couple different options in naming the SSID on the 615 set-up. If I name the SSID on the 615 the same as the ActiveTec router, when I go to Connect to a wireless signal where there is overlap, there are two signals that one can connect to, named the same SSID, the Fios is WPA2 secured and the 615 is not. Shouldn't these all be on one SSID? It seems that I have two different networks (different SSIDs) instead of one (rather than the 615 simply serving as an extension of the Fios router as a wired remote access point) with different security protocols (WPA2 and None). The SSID name almost seems meaningless. If I name the 615 SSID the same as the Fios router SSID or something different, I still have the option of selecting one SSID that is secure and one that isn't. If I try to connect to the SSID name associated with the 615 I can get on without providing a password.How do I make it so that one can walk around and go from one area to the next and seamlessly move to the best signal? I did read to select different sets of channels for each access point.

I recently upgraded from Linksys WRT54G to D-Link DIR-655 firmware version 2.0. All the features are working as advertised however i am having difficulties accessing UPnP services in my network. I have a Samsung 55" internet enabled TV connected to the router and also have few devices that can stream over UPnP to the TV. The option to enable the UPnP is enabled in the router configuration however its not finding devices in the network ... comparing that with Linksys ... all i had to do is enable the UPnP and all my devices discovered each other and started streaming without any issue. What do i need to do in D-Link to enable the UPnP devices ...

I have been doing network and computer work for a small public library which will soon be needing to change internet providers. Our planned route will be to have a fiber connection directly from our local ISP, but we need to figure out the best network hardware to accommodate this network connection.We currently have two HP 1810-24G switches connected to a Sonicwall TZ100 firewall as the primary router. The firewall/router connects to the internet with Cat6 connected to a fiber optic media converter. The media converter is on lease from the current internet provider so it will be gone.Our new ISP has said that they can provide a fiber connection in our building to an SFP port termination, which is their recommendation. Ideally, this would be an SFP port in a router or firewall. However, there seems to be very few options for routers with SFP and they're all incredibly expensive compared to a network switch with SFP. While I imagine we could just terminate the fiber optic connection into a cheaper switch with SFP and connect to that with the firewall, our network is further complicated in that we have a CISCO LifeSize video conferencing system which ideally runs best without running directly through the firewall, which can cause some lag and glitches in the signal it seems. I don't believe it's possible to have the router WAN interface connect through to the ISP with a static IP and PPPoE sign on as well as another network devices using the PPPoE and a separate static IP address, am I correct?Have I just over-complicated this network issue, and everything should just be run behind the existing firewall, or should I be able to find a different firewall/router or switch that can connect with SFP to the ISP?

I currently have CenturyLink (Qwest) DSL (12Mbps/896Kbps) and Comcast Cable (12Mbps/2Mbps) going into a Cisco RV08. I redirected all DNS traffic to the DSL line as an experiment with no decrease in web browsing speed. e are rural and speeds fluctuate considerably during the day. It seems like it's more of a response issue than a bandwidth issue. I would like to order a 2Mbps dedicated line from Comcast to use for DNS and VOIP traffic only, the DNS resolution times should be faster on that connection. There would be several tenants in this building using it for that purpose. The secondary purpose of this line would be for backup internet connectivity
