Multiple Networks Different Subnets Windows 7?

Jan 24, 2013

I have a Windows 7 Pro Desktop with an on-board Ethernet and an Axis USB To Ethernet adapter. The on board Ethernet is configured as dhcp and obtain the address with subnet. The Axis USB to Ethernet adapter is static ip configuration with and as subnet. Under the adv settings I have also another ip with subnet. When the Axis is communicating network I can not access the internet using the on board Ethernet I have to disable either one of the cards to access one network at a time.

Why Should Wireless And Wired Networks Be On Separate Subnets

Oct 24, 2011

With traditional classful subnetting, the same number of host bits is used to designate the subnet ID for all the resulting subnetworks. This type of subnetting always results in a fixed number of subnets and a fixed number of hosts per subnet. For this reason, this is known as fixed-length subnetting. The decision about how many host bits to use for the subnet ID is a big planning decision. There are two considerations when planning subnets: the number of hosts on each network, and the number of individual local networks needed. The table for the subnet possibilities for the network shows how the selection of a number of bits for the subnet ID affects both the number of possible subnets and the number of hosts that can be in each subnet. One thing to keep in mind is that in all IPv4 networks, two host addresses are reserved: the all-0s and the all-1s. An address with all 0s in the host portion of the address is an invalid host address and usually refers to the entire network or subnetwork. An address with all 1s in the host portion is used as the local network broadcast address. When a network is subnetted, each subnet contains an all-0s and an all-1s host address that cannot be used for individual host addresses.

Cisco :: Multiple Public Subnets On Asa

Mar 2, 2012

I've currently got my ASA (5505) serving a /28 public subnet. I've ran out of IPs, so my DC has issued me an additional /24 subnet that they have routed to my ASA. What needs to be done on my ASA so be able to use these new addresses? I've been trying to search and not been able to find a good answer (some say I shouldn't have to do anything, everything else references NATing, which I currently don't do and would rather not do).The servers I assign these to, I'd like them to have the public ip assigned directly to them.

Multiple Public IP Addresses From Different Subnets On 1 Router

Feb 20, 2012

Is it possible to have multiple public IP addresses that are from different subnets going through one router? I have been told that this is not possible with most routers and that I would have to spend a lot of money on a router to be able to do it. I am still not totally clear on what defines a subnet even after reading up on them. What I am trying to achieve:

-My office has 10 computers.

-All would be connected to one router.

-My internet service provider has provided me with 10 public IP addresses, that are all very varied (which I asked for)

Cisco :: SG200-08 Setting Up Multiple Subnets

Aug 26, 2011

I am setting up my home lab to practice and play around.I have VMWARE ESXi environment with two workstations as my servers.I would like to setup two domains with two domain controllers  but i want each domain to have its own subnet.So this is my setup. I have Cable modem from cablevision , thay connects to my router which is Apple Airport which acts as the DHCP server. DNS server and default gateway. The network on the router is 10.0.1.xThen i have two switches . One is a 5 port unmanaged switch that connects to the three physical desktops .Then i have a Cisco small business switch SG200-08 that connects to my ESX servers and NAS. Now currently all is good and working but like i said all my machines physical or virtual get an IP that is 10.0.1.x and they get all this from the router. And i think i can setup two domains with two domain controllers without an issue and they will all get an IP address of 10.0.1.x. This is all good but i want to have one domain on one subnet and other on another so for example one domain will have 10.0.1.x and other 10.0.2.x. I am just not sure what i need to to  get this setup like this. I know my SG200-08 supports vlans and i am pretty sure on the apple router you can only have one subnet i think. So can i do this with my current setup by setting up a DHCP server with two scopes ?

Cisco Routers :: RV042 Multiple Subnets

Jan 22, 2013

Here's what I want to do with my RV042: I have a bunch of devices, including a server, inside my network at
I've set up VPN using PPTP. It works, but if my clients have their own remote DHCP set up to 192.168.1.x, they can't get to the server. If their home DHCP is 10.x.x.x., everything works
I am considering changing my internal network to something obscure.
My server has two NICs. So I thought, I why not set one address up to 10.x.x.x But the two nets can't ping each other. I tried using "multiple subnet" on the RV042, setting up, but no luck.

Cisco Routers :: RV042 VPN Tunnel For Multiple Subnets?

Aug 5, 2011

We have 4 RV 042 routers and  cisco router at HQ, we have Site to Site VPN tunnels in between, All branch offices are connected to HQ via S2S VPN tunnels 24 HQ Branch 1 Branch 2 Branch 3 Branch 4
now lets say i am branch 1, i can access network but cant access network, means i dont have branch to branch connection, it should be through HQ, means my RV042 at brnach  should fwd all traffic to HQ for another branches also. Under VPN tunnel if i try to configure remote destination its not allowing me it says network overlaping with local network, how i can sole it, I know how to do in cisco, we can permit those networks in access lists.

Cisco Firewall :: PIX 515E - Multiple External Subnets

May 23, 2011

I have an existing pair of PIX 515E that has two interfaces. One connected to the public internet via my ISP and one internal.  
I recently ran out of IP's and had the ISP route an additional block to public IP of my firewall. This isn't working for some reason and I'm trying to figure out why.
The "ip address outside XXX" command defines the outside address and I don't see any way to add a secondary sub net.
I tried just adding a rule to the firewall for one of the IP's in the new subnet, but I can't seem to get traffic to pass though the device.

Cisco Routers :: RV042 Protocol Binding Multiple LAN Subnets?

Aug 16, 2011

We have Point to point T1 environment where 3 additional WAN sites get internet access through our RV042. When we setup load balancing we have problems with https traffic, so we setup protocol binding for https and everything worked great from the local LAN. When trying to access https content from the remote LAN across the WAN the sites failed and I see no option to add additional subnets to the protocol binding. Is there a command line feature that supports adding additional subnets for protocol binding or is the local LAN the only option?

Cisco VPN :: ASA5505 - Multiple Distinct Inside Subnets And VLANs?

Nov 17, 2011

The ASA device is going to be the gateway for multiple distinct inside IP subnets.   We can have have a unique outside IP address to correspond to each inside IP subnet if needed, but we need some means for a VPN client or a site-to-site VPN to have acess to a pre-definied IP subnet (i.e. if customer A establishes a VPN connection, they have connectivity to IP subnet X; customer B establishes a VPN connection, they have connectivity to IP subnet Y, etc.).Currently, the two inside IP subnets are and We will be adding more.The problem we are facing is that we cannot reach the VLAN 201 from the ASA we believe this is because. I have setup two addresses on port 0/1 Vlan1, and as an alias. How can we make traffic for the subnet untagged and traffic for the subnet tagged for VLAN 201.

Cisco Routers :: RV180W VPN Configuration / How To Choose Multiple Subnets

Jan 4, 2013

I have setup 15 x RV180W's so far for a particular client.They have requested that we add a Corporate Wireless VLAN for their laptop users (not guests) and add a Special Use WiFi VLAN for a particular mobile platform that is being deployed (in this case we need 2 separate WiFi VLANs to ensure compliance).Also, none of the VLANs can talk to eachother and they have their own subnets.I have the Wireless and VLANs setup, no problem... but I am having an issue wiht the VPN settings.I have the wired network's subnet working fine. But I do not know how to add the subnets for both Wireless VLANs to the traffic selection.The IP schemes will not allow me to just select a large subnet... here are some examples:
Wired VLAN: 10.10.x.y
Corporate WiFi VLAN: 10.15.x.y
Special WiFi VLAN: 10.18.x.y
x is the octet that defines the physical unit location (unit 1 = .23, unit 2 = .24, etc...) y is the octet the host.Since they are not in a contiguous block, I cannot just use a larger subnet mask.I can add multiple traffic selection rules to the ASA5515 at HQ, so that side of the tunnel is perfect... I just don't know how to add the three VLANs to the RV180. Is it as simple as using commas or semicolons?

Cisco Firewall :: Netgear FVX538 - Multiple Subnets On SA520

Jan 5, 2012

I am new to Cisco products. We have currently got a Netgear FVX538 running in front of a few servers. We currently have 2 ranges of IP addresses provided to us on 2 separate subnets. We configured the netgear box with the first IP addresses of each subnet as the IP address of each of the primary and secondary LANs. This then allowed us to set the gateway addresses of servers on the network to either of those 2 addresses, depending on it's range.
This all worked fine - except for the fact that the Netgear box is incredibly flakey, so we decided to get a Cisco box.
We have gone for the SA520, which I have been trying to configure this afternoon. Unfortunately I am now having concerns as to whether it is possible to configure 2 separate subnets internally on this box in the same way we have done with the netgear box. ie - classical routing, one incoming WAN interface with multiple subnets?

Cisco Switching/Routing :: 2901 - Multiple Subnets On Same Vlan Switchport?

Jun 29, 2012

I have a Cisco 2901 with the 4port gigabit ethernet switch module that I'm trying to get configured to have a seperate subnet for each port.  So far I have it set up so each subnet is a vlan, then on each port I use the switchport access vlan command to tell it which subnet I want that port to be on.  However, there is one port that I need to have 2 subnets on.  The way I found to do that was to use switchport trunking on that port, but it doesn't seem to be working properly. how they would configure this?  Right now I have vlan 101 as x.x.x.17/28 and vlan 103 as x.x.x.53/30.  I think where I'm getting hung up is the proper association between the physical port and the vlan subnets.

Cisco WAN :: 6509 Fwsm Multiple Subnets Routed On One Port From 3750

Dec 20, 2010

We have a 6509 that was connected to 2 other locations(location A and B) and our local lan (location MAIN).  We wanted to move the location A and B to a 3750 switch and only allow the traffic that needed to access our location MAIN to come through the firewall.  The only problem I ran into is that before location A and B were on different interfaces so in the 6509 firewall the routes for traffic to our MAIN location was done by static routes.
static (MAIN_intf,A_intf) netmask 0 0
static (MAIN_intf,B_intf) netmask 0 0


because it has a static overlap, which makes sense to me, but my question is how do I configure the network to get this to work?  Do I have to reconfigure my network and access-list?  Do I need to add more ports between the 6509 and 3750?  I'm not sure if this is the best way to do what we want. If something is not clear I'll try my best to explain the setup, but I just took over for our I.T. guy when he left.
I put instead I should have put the routed port is on a different subnet than the computer I'm trying to access.

Cisco Routers :: 3750 / RV042 And Multiple LAN Subnets Access To Internet

Nov 27, 2011

We have RV 042 deployed for internet access/firewall purposes. Due to growing number for Wireless devices and also to separate WLAN traffic from wired devices, we have created a separate VLAN/IP Subnet for the wifi devices. We are having trouble accessing the internet from the WiFi VLAN/IP Subnet.  Cisco 3750 is layer 2 and layer 3 device. We have VLAN 1 (, all wired devices and RV 042 are part of VLAN 1. Connectivity to internet from VLAN 1 is good. VLAN 2 ( / was created for wifi devices, 3750 does the inter-vlan routing, I have enabled the multiple subnet feature on the RV 042 and added / 24 to the subnet list, we still have issues accessing internet from vlan 2 devices.
As a workaround, I shutdown vlan 2 and added as secondary address to the VLAN 1 interface on 3750 and i was able to access internet from network with wifi devices also on vlan 1, we want wifi devices to be on separate vlan / ip subnet. Looking at the documentation for RV series routers, it talks about supporting multiple subnets access to internet by enabling multiple subnet feature but it doesn't seem to work.Are there restrictions on having multiple vlans?

Multiple NIC's - Two Networks?

Feb 14, 2012

I am having trouble setting up two networks.Basically, i want one 'private' network and one public network. The problem is, the private network can't access the internet.(Network 2)

Network 1(Public) works fine as i don't want them to access Network 2.Here's how it is setup.

Router/Modem (Network 1)
Server NIC1
Server NIC2
Switch - (Network 2)

Network 1 can access the internet and shared files on the server.

Network 2 can access Shared files on the server (which is what i want) but cannot access the internet.

Router/modem IP is subnet

Server NIC 1 IP is subnet
Server NIC 2 IP is subnet

How can i get computers in Network 2 to access internet?

Cisco Routers :: Getting VPN Gateway To Gateway With NAT For Multiple Subnets / RV082?

Feb 11, 2012

I have a pair of RV082 routers and I'd like to configure gateway to gateway VPN tunnel as described in a cookbook, "How to configure a VPN tunnel that routes all traffic to the Remote Gateway," (file name Small_business_router_tunnel_Branch_to_Main.doc).  I followed this cookbook and found that my while the Main office has internet connectivity, the branch subnet doesn't have internet connectivity. 
Routing does behave as advertised, where all traffic does go to the main office.  However, the subnet in the branch office does not get internet connectivity.  I've read in other posts that the Main office router will only provide NAT for the local subnet, not the branch office subnet.  Is  there a way to configure the RV082 router to provide NAT for all subnets?
If not, which Cisco product will provide the VPN Tunnel connectivity as well as the NAT for all subnets?  Can the RV082 be used as part of the final solution or are my RV082s a  wasted expenditure?

Following is the configuration that I'd implemented, (real IP and IKE keys are bogus). 
Gateway To Gateway    
Remote                                                   Main Office
 Add a New Tunnel
Tunnel No.                  1                                               2

Connecting Multiple Computers Through Different Networks?

They are all connected to the company network for internet and access to shared network drives.The computers are used for media (mostly video) production and we need to move large files between the computers easily and quickly. The current network (company wide) is slow and unreliable, so I would like to create a separate network for these four computers and have them connected to both the company network and the office room network. Each computer already has two network ports and I have a router I can use.
