Making 4 Subnets For VLANs?

Dec 4, 2012

You have to make 4 subnets for 4 VLANs, the router interface assigned to each VLAN is the LAST usable host on the unless I'm really bad at networking the graph should be:

NET ID // HOSTS // BROADCAST ADDRESS // VLAN // - // // VLAN1 // - // // VLAN2 // - // // VLAN3 // - // // VLAN4

So if I'd have to write down a single host configuration for VLAN2..I think it should be:

subnet mask:
default gateway:

Is this correct? I'm not sure whether the default gateway should be (as would with normal subnets) or as I wrote down, this is the first time i've ever gotten assignments including VLANs and I havn't really gotten a solid explanation.

Cisco Switching/Routing :: Isolating Two Different VLANs With Subnets On 6509E Sup 2T

Oct 1, 2012

I have a pair of Core VSS 6509E SUP 2T. Two different LANs, two diff. Subnets. larger LAN has been connected to the VSS pair usng normal SVI and Post-Channles (has lots of closets 3750 stacks) and no problem. Second LAN, two closets, stacked and connected to each other via Port channel and trunk + SVI interfaces. Now, I have SVI interfaces for both LANs on teh VSS pair and that is causing traffic from one LAN to jump over to the other VLAN and rightly so because the VSS pair see both subnets as directly connected subnets. I was wondring if I delete the SVI for the second LAN and only keep the L2 VLAN this will be resolved> The reason for the second LAN to connect to the VSs pair is only that It has to go through the VSS pair to get to the WAN router (both LANs will go out through this Same WAN router) but WAN router is not my concern at this time. I need to isolate these two LANs/subnets traffic so no one VLAM traffic jumps over the other.I have also thought about VRF but at this point I am not sure if teh 3750 stacks supports VRF and if it does how to implement VRF on the second and samller LAN to just allow it go through the VSS pair in order to get to the WAn router.

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.

DELL 2816 - Benefit Of Setting Up VLANs If Subnets Wired Separately

Jun 12, 2013

I have 2 sub nets within my office: and All devices on each subnet are wired independently from each other into the server closet. Previously each sub net had it's own switch in the closet to connect to that sub nets servers. We are replacing the 2 switches with a single Dell 2816 managed switch.

Is there a benefit to setting up the switch with 2 VLANs over just letting everything pass through the switch in un managed mode?

My only security concern is this: 1 sub net has access to the internet while the other does not. Does setting up 2 VLANs provide additional security by preventing 1 subnet from accessing the other? In other words, if a computer with internet access gets hacked will it being on one side of a VLAN prevent the hacker from accessing the other subnet?

Making Computer A Wireless Hotspot?

Dec 19, 2011

I have a computer hooked up to the internet with a cable modem via usb cable. The ethernet part of the modem is hooked up to my xbox 360.

I don't have a wireless router or a wireless internet connection but I do have a Belkin USB Wireless Adapter and I read on the web that you can turn your computer into a wireless hotspot if your computer has a wireless card with antennae or a usb wireless adapter.

Example, I have a Nintendo USB Wireless Adapter. All I do is stick it into my computer's USB port and it becomes a hotspot that I use to connect to my Nintendo DS to the internet wirelessly. So I basically thought that my Belkin adapter would be able to do the same thing only with whatever other devices I try, not my DS.

DLink DI-624 - Router Not Working Or Making Connections

Mar 28, 2012

I'm running XP and have Bell-Aliant modem SIEMENS Gigaset SE567 running to DI-624 router. It has been working for years but after the internet was down in the area for most of the day, it has failed to reset. I've done the usual un-plug/wait/replug routine a few times but cannot connect. I can connect directly through the SIEMENS but when I introduce the DI-624 back into the mix, I'm not able to connect to the internet. How do I make it happen. I'm not tech savvy so go slow.

In reading some of the other post seems hit or miss on adapter seeing and working with routher. Is there a brand or type of adapte I should look at? as I said Desktop will now be wireless media hardwire dose this sound like the way to go about doing this? Any media server that seems to work better than others . not doing x box or Wii not a gamer just want to stream Netflix without buffering and as good a picture as Poss.

Cisco VPN :: WRVS4400N To Change ISP And Making Changes In Firewall

May 12, 2011

We have a customer that recently changed IT Vedors and came to us. We needed to change the ISP and need to make changes in their Firewall. I went out on site and wasn't able to get into the Routers and I contacted the previos company but they wouldn't release that information. So we had to reset the devices and set everything back up. Everything works great except before they had an IPSEC VPN Tunnel between the 2 buildings. Both Buildings have WRVS4400N Routers and I have setup a VPN IPSEC Tunnel on both sides. I have named them the same and the summary says that both are up. But when I try to go from one side to the other I am unable to Ping or resolve anything. I called Cisco but they said they are out of warranty. Cisco directed me here.

I am trying to get the ACS 5.3 to work with NCS but cannot make it work correctly. url...But this does not show how the ACS referencing AD groups would work when determining which custom attributes to use.
On the ACS 5.3 i have set up the following .The ad is working and in Users and identity stores/External identity stores/Active Directory then my AD test works fine.I have set up the  Users and Identity stores/Identity Groups with appropriate ip s.I have configured the Network Device Groups/Network Devices and AAA Clients with the ip address and Authenication optionsA.In Policy Elements/Authorisation and Permissions/device administration/shell profiles.I have creeated a shell  profile called network shell pro which das a common tasks of def priv = 0 and max priv = 15

Now i can get into the NCS but i do not see any of the administration buttons on NCS - so this means the custom attributes are not working.i shouldnt need a user for this on the ACS as its using AD.

Possible To Extend Wireless Signal Without Making New Access Points

Jan 18, 2012

At the moment i have 3 routers across the house, each acting as a wifi access point.My problem comes to when i use my phone or laptop, it connect to a random access point doesn't matter of the signal.Is it possible to combine 3 routers as one access point. So that i would connect to one access instead of 1of 3 access points, that would be a strong wifi signal no matter when i am in the house. Something similar to what bit malls or stores have.I have looked at wi-fi repeaters, but they just repeat the wifi and make new access point.

I understand that some wireless devices can affect a router and that these are usually 2.4ghz devices but I have no idea if my cordless telephones are 2.4ghz or 5.8ghz or indeed if this is the source of the problem at all.
