Cisco :: Dealing With Security When Merging Private And Public Networks?
Jul 18, 2011We have a private network, multiple vlans etc. for our domain users/employees across several amenities. We also have a Public network, that we have managed by a 3rd party for guests/conference rooms/attendees.Private network is all static ips, mac restricted port security, as strict as possible from a security and PCI Compliance standpoint. The public network is all DHCP with hundreds of users. Having them physically separate has always been the best option. Separate switches, server, and I even have the uplinks separated on a 3825 router. However, unfortunately it seems as though that luxury is coming to an end.One of the meetings that is taking place is going to be at one of our outer amenities so I've got to push that "public" network through my network, over my backhaul to the other side.
My suggestion was to create a new vlan on the switches with the shortest path possible to get where it needs to go. This way the traffic never goes through our ASA, and it has a small footprint on our network, it plugs into the switch access port with the dedicated vlan at the entry point into our network, and leaves from an access port on the other end. To me that seems to be the best/most secure way to handle it. We're also in the process of rolling out Public Wifi through the entire property and since we'll want to push both Public and Private vlans over it....merging the two networks to a point is only inevitable. Especially since it will be going through a controller and the property covers a good 7000 acres.
A good IDS/IPS...other than already having port security on every port, I'd definitely like to know if somebody inadvertently cross connects the two networks and it starts flooding whatever vlan access port it's plugged in to with dhcp...especially since a lot of the laptop users on the domain are set to DHCP first with a static in the alternate for working at the office and remote.
Cisco Switching/Routing :: 4500 Max Spanning-tree Instance When Merging Networks
Feb 23, 2013I have been tasked with migrating 24 access switches from their current distribution switches, 2x stack 3750's to a their new 4500 distribution switches. Ideally with no downtime. My plan for this was to connect the 4500's to the 3750's and create replica vlans on the 4500's therefore spanning the L2 broadcast domain across both sets of switches.
Each one of the vlans that had been created on the 4500's would have the STP bridge priority set to 4096 and 8192. When one of the uplinks from the access switches to the old 3750 stack is connected to the 4500's, as I understand this should have a stp cost of 4 and move the old uplink into discarding therefor passing traffic across the new link. This would then allow me to disconnect the old link and connect it to the second 4500 as the L2 traffic is spanned between all switches. Not ideal but the only way I can see this working.
Once each of these switches have been moved, the SVI's and static routes will be moves from the 3750 stack to the 4500s.The problem I have is that I've ran out of the available STP instances I can use, these 3750's all seem to be at 128 already so as far as I know, is that if a loop was to be formed when the 128 allocation is hit this would indeed cause loop in the network.I have a total of in use vlans to be spanned of 700. I'm unaware how many instances of stp the 4500's can deal with however I can bet it's not 700. 3000 logical interfaces I believe is the maximum I can see online with regards to how many stp instances the 4500's can use.
Home Network :: Merging Hard Drives In XP?
Jun 20, 2011How do I combine two (or more) physical drives into one on an XP based machine? I have an older machine I want to essentially use as a NAS type device over my home network to stream content from, but want all the installed drives to essentially be "merged" together to show as just one if possible. I think its sometimes referred to as "disk pooling". I have XP Pro available to install so maybe this has something built-in that can easily handle this task. It also needs to be done on an XP based machine (not Linux) due to some other specialized software that will be running on it for another reason and is for XP only. Basically, any suggestions on how to have some sort of 'disk pooling' for 2+ drives on an XP machine? Can it simply be done within XP Pro? Or maybe there is some sort of free software out there that can handle this. This machine currently doesn't have any important data on it so experimenting and wiping something out can be done if needed.

Feb 18, 2013Our work building currently has 2 separate DSL lines feeding into it, one on each end of the building. The reason for two lines was so each one would have its own bandwidth, thereby supporting more simultaneous users. There is a router connected to the DSL jack at each end of the building, broadcasting its own wireless network: let's call them Work 1 and Work 2.Is there any way for me to connect the Work 1 and Work 2 wireless networks, so that they appear to the end user as one contiguous network?

Apr 1, 2012My dad has a business he runs on our network that everyone in the house uses for general needs. I am a gamer and often want to host servers for my friends. This requires that I have ports opened on the router, which I cannot do as I don't have access to change the network. Is it possible to create 2 networks on the same ISP, and if so how would you do it?,I have my current network running on an Apple Time Capsule with AirPorts around my house acting as extenders.

May 1, 2011I have 2 PCs at home. Lets name one of them as PC 1 which has two onboard LAN Ports. Now, PC1 has to connect to PC 2, just a home network for easy transfer on files and stuff, and it also has to connect to the internet via a network. The problem is both of them use static ip and when I tried configuring PC 1, it allows only one of the connections to remain active. I simply get an error otherwise saying "Multiple Gateways" will cause conflict and I will be stuck with only one connection. After much study I "somehow" connected both. I vaguely remember using the "route" command in cmd to achieve this. But now, I am getting an error when I try to access PC 2. My Internet is working fine.I am not network savvy at all. run both these connections from PC 1. I should add that I can in no way modify/change/or do anything else to my internet network since it is out of my control. I can do anything, however, for my Home Lan with PC 2. I run windows 7. Both the connections are wired, by the way.

Aug 15, 2011We have three computers (one of which acts as a file server) plugged directly into an internal office network. Then we have another such connection leading to the WAN port of a router which shares a single connection among another 5 or so computers & laptops. So the WAN connection is providing internet access AND access to the file server.
Since upgrading to a new router, it is now not possible to "see" the file server from the computers connected to the router, although the internet can still be accessed without a hitch. This has now become infuriating as I've spent several hours changing all possible router & IP settings to no avail.
Won't Connect To Certain Networks?

Previously I could connect to any available network as normal, but all of a sudden I can't get onto certain network connections despite the fact they are available and at full signal strength. Some connections are fine, others are not.Something odd happens when I unsuccessfully try to connect: a window pops up but in the blink of an eye disappears again before I have time to register whether it's an error message or what.I've checked for Window updates and am fully updated, I've run my virus scan (Microsoft Security Essentials), and I've performed Windows Network Diagnosis to no avail.otel overseas and am now feeling the problem as I can't get onto the hotel's free wifi and am having to use my iPhone as a personal hotspot which is costing me a bomb

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 10.10.1.254 subnet 255.255.255.0
Server NIC 1 IP is 10.10.1.252 subnet 255.255.255.0

Becuase of this i connected MY PC directly to my ISP's modem so i dont keep crashing the router.
This all works fine, but i recently purchased a network storage drive that i would like every one to have access in the house.Becuase the Storage drive and my PC are on the IP range 192.168.2.xxx and everything connected to the router is on the IP range 192.168.1.xxx how can i give everyone access to the storage drive ??I know if i reconnect my PC and drive back on the netgear router it will work but i cant do that becuase of the location and becuase of the original issue of when downloading on my PC it would block the router.

Apr 13, 2012Our church has two internet connections, one that the internal network accesses and one that the wireless network in the building accesses. For (obvious) security reason we need to keep the networks isolated from eachother. On sunday's when we upload the sunday sermon video recording we caused a network lag for other computers on the network, thus the church has asked us to use the wireless network to upload the videos. We record the video on one computer, then can transfer it to a Mac that has 2 network cards.
How do we isolate the two networks from eachother without plugging and unplugging cables and have the Mac upload through the wireless network instead of the wired network?

The smart phones and Windows 7 computer have never had a single problem connecting. My daughter has tried to use one of the XP machines at some coffee shops with no success, I assume they are "N" networks.
