Routers / Switches :: Multiple Gateways On A Single Router?
Feb 28, 2011
We are in the process of installing time clocks at some of our sites around the USA. Our security department has asked that the time clocks be completely isolated from the rest of the network. The time clocks will be administered by ADP via a centralized firewall utilizing NAT. We have multiple subnets available at each site. Let me give an example to calrify what I would like to do. Example: Site A has 10.168.19.0 /24 user subnet and is configured for VLAN1 using 10.168.19.1 on the router as the default gateway. I would like to use subnet 10.168.20.0 /24 for the time clocks, configure it for VLAN2 and use 10.168.20.1 as the router gateway address for VLAN2. This should allow me to NAT one of our additional public IP addresses to the 10.168.20.1 gateway address thus completely isolating the time clocks from the remainder of the network. Problem is I have not done this before so I'm a little confused about how to configure it in the Cisco 3750 switches.

I want to setup an home network with a wireless router and use multiple switches for wired connections through out my home. I currently have an Airport extreme hooked up to a cable modem and a leviton gateway hooked up to the Airport. The 2 computers connected to the Leviton are on a windows 7 homegroup and share fine, but won't share or discover any wireless device connected to Airport. My main goal is to have a wireless/wired network with all computers sharing information with each other. I want 2-3 wired switches/gateways with a min of 2 devices connected to each, connected to my wireless router whiich is connected to cable modem.

We our currently using site-to-site VPN tunnels to connect our multiple offices using static public IP's via ADSL connections.We wanted to get an additional ADSL connection from a different ISP so that if one connection drops, the other could be used.Are there any hardware devices or tricks we can use to automatically get our networks to failover to use the backup ADSL connection and have our VPN traffic remain up?

I am trying to create a VPN between an SRP547W and a Cisco IOS router, in this case a UC540.I am running firmware 1.2.4 (003) Jan 11 2012. Now I can do this with an SRP527W and many other routers successfully. Including other IOS routers 1801, 1941 etc.
The issue I have is on the SRP547W I cannot create more than one IPSec Policy through a single IKE policy. I require this to route multiple v lans to our remote site. When I try to add an additional IPSec Policy I am give the error "IKE policy has been used by other IPSec policy"
This is possible to do on the SRP527W with latest firmware. I have tried rolling back to earlier firmware but instead I am given an error about overlap. Latest release note for this firmware suggest this issue was already resolved.

We have a HP Procurve 5412zl switch as our default gateway for all our VLANs from there the traffic will be going to a Cisco ASA 5515 and then to a Cisco 3800 Router then to our ISP.
We have yet to purchase the ASA but my question is about my future configuration. I will have the router of last resort on the 5412zl setup to point to the ASA inside interface, how does that work with multiple VLANs? For instance the ASA inside interface would be 10.0.0.1 but traffic could come from another VLAN via the switch with a 192.168.1.x address. Would the ASA just pass it on to the router? Or would it conside this spoofing and drop the packet?
Lastely, if we have WCCP set for the ASA's inside interface, how would it handle the redirect for multiple VLANs ip addresses? Would I use GRE for the redirect to my web filter?

remote location on MPLS circuit terminated on a Cisco router that has Internet connectivity through Central Site router. We are installing a cable modem at the remote location that is to be used as the Primary Internet Connection but still be able to use Internet through MPLS if the cable Internet goes down. We want the failover/fallback to be handled automatically.
We have an ASA5505 for the cable Internet which then feeds into the ISPs modem.
At first I was thinking about getting a module for the remote router so the cable Internet could be terminated on the remote router as well but that introduces a single point of failure. I would also like to firewall both the MPLS and the cable Internet but if I do so on the ASA there is another single point of failure.

This is the situation in our Lab.We have one telephone line with broadband connection and a system which is connected to a modem to use this broadband facility. Recently we have taken two static IPs over this connection for a project work.Now what I want to know is, how to configure these static IPs, so that I can connect two systems (each one to one static IP) to use these static IPs and continue to access the internet in the 3rd (already present) system.

We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are 192.168.184.0/24 & 192.168.186.0/24. We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .
Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]

In my office we have concrete walls and very limited wiring. The way it is set up is we have a Verizon DSL Modem that comes in then I have a router with it that splits the signal to 4 other routers that each split the signal 2 to 3 more times. I have to use routers so that it assigns IP addresses.I bought a new D-Line N300 Wireless router with USB imput. I want to attach my Home Media Network Hard Drive Cloud edition to the 1st router (attached to the modem) and then share the data off that hard drive with everyone connected to the sub routers.

At my company, we lease 3 static public IP addresses from 1 ISP. We want to have 3 separate networks that each use one of the IP addresses. Network 1 is the computer network, network 2 is the VOIP network, and network 3 is the security camera network. I am trying to determine the best way to do this. I have come up with 2 solutions in my head, but I'm not sure if they will work or not. I would like to get some input. Solution 1:Solution 1 looks something like this. Fiber box -> Router-> 3 switches. There would be one WAN input on the router, that would have a static route to 3 different LAN ports. For example, address 24.244.208.101 would be assigned to LAN port 1, 24.244.208.102 would be assigned to LAN port 2, and 24.244.208.103 would be assigned to LAN port 3 (by assigned, I mean have a static route to it). Is there some type of router that is capable of doing this? Solution 2:Solution 2 looks something like this. Fiber box -> Switch -> 3 Routers. The ethernet cable would run from the Fiber Box to a switch, and then 3 routers would be plugged into the switch. Each router would have the Static information configured in them. Would both of these methods work? If so, which would be the best way to go?

I'm going to move offices into a shared situation with 3 companies. Each company will want its own private network so there's no snooping between companies. I am planning on using VOIP for the phone system (Nextiva cloud based). Is it possible to set up the system so that each company has access to the VOIP system but yet remains sequestered in the their own network for everything else. I was hoping to do this with one data port at each workstation using Cisco SPA-303 phones. The way I understand this, is that the phone plugs in to the data port and you daisy chain the workstation off from each phone. Is this possible to do this while having the system I described? Another wrinkle is that I'd also like all the networks to be access shared printers.

Am trying to understand how we can have multiple IP addresses on a single NIC and what are the restrictions on the same. If i can have two IPs from two different networks present on a single NIC, then why would i ever get a new NIC?
Also, i want to understand the concept of virtual IP and how it fits into this picture.

I have an older DELL power edge 2800. Currently we have 2 NIC's one for the WAN one for the LAN. I wish to increase my users access speed. Can I team and or bond up to Four NIC's on the LAN side and leave the single NIC for the WAN? I am having trouble finding any info on the net for pulling this off. I have 67 users and throughput is getting a little rough.

Is it possible to assign a single ssid to multiple interface groups by assigning the ssid to multiple AP groups?
I have buildings geographically dispersed that are configured with multiple vlans in interface groups so that I can maintain an addressing scheme of dhcp assigned addresses per building. Each building is also further grouped as AP groups. I'd like to know if by assigning the same wlan ssid to each of the AP groups, will I maintain addressing integrity for each building? I'm thinking it will work.
Do the buildings have to be outside AP range of each other to avoid problems?
5508 controller
7.2.110.0 code
6 buildings
6 interface groups
1 ssid

I need to put a few cameras, without a server, on a static WAN ip address. Do I just assign them a static LAN ip address(for example 192.168.1.200), make sure the port they use is open, then type the WAN static ip address then colon and the last address? Like this.....I'm making up the WAN address....45.34.55.334:200

some of the servers are not pinging from one switch but they are pingable from other redundant distribution switch. So I took the IP addresses from the redundant switch, with that I found MAC addresses from the access switch.But when I tried to see to which ports these MAC are addresses are connected to, multiple MAC addresses are resolving to the same switchport. like 5 MAC's are showing to 1 port and other 3 MAC's are showing to other port, like this there are many. All these MAC's belong to virtual servers.

I currently have mutiple computers at my place. Once the computer turned on i want the option of which login for the current computer to use, it can login it current computer or the mutiples computer with their content/data all inside. So more like an computer linked. Example, it can only to A or B, A is the current computer data, while B have all the data of the different computer monitor datas, and if i login B it will show that current computer info. And same goes to the B computer, i can login to A or B on the B computer. What makes this very good is that, both the computer logins are sort of connected, for example if im on actual computer A, but logined to computer B and downloaded/changed some files/data on the B login, once i login on computer B to login B, the changes will apply even tho the changes are done in computer A.

We have a project in which we are using 34 Cisco SG200-18's each with a MGBLX1 (LC Single Mode Fiber) SFP mini-GBIC.All the fiber's come back to one building where we must "bridge" all 34 fiber connections. What hardware should be used to accomplish this? A L2 switch? For example, a 12 port SFP Switch with Fiber SFP's accepting the first 12 fiber connections, then other switch with SFP for the next 12 and so on, until there is a overall capacity of 36 and having patch cables between the 3 switches?
what cisco or non cisco hardware would work with these SF200-18's to accomplish this?

Our 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?

setting up a simple internet plan for a place, but a LAN center needs crazy fast internet, faster than most large enterprise class offices that take up an entire floor or two. Otherwise there is too much lag in games like first person shooters. We are expecting to have 60 computers, plus people bringing their own gaming rigs from home and laptops as well, xbox, ps3 and other consoles, all accessing the internet at the same time to varying degrees, with no room for lag. There is a LAN center in california that has 200 or more computers and they pay for 9 t3 lines, which is thousands and thousands of dollars per month. Plus the initial equipment to set that up from what I can find on cdw is many thousands of dollars also. Something like 10,000 for a router with 4 expansion bays, and 4000-6000 dollars for a t3 expansion card, bringing the total to around 22-28,000 for equipment to do just 4 t3's. Plus the monthly cost. Since we don't need all of the traffic to be secured like a high end business class line like a t3, I was considering what it would be like, and how one would set up, having multiple cable internet lines coming in. They make cable wic cards for cisco routers. 4, 50meg cable lines would give us 200 down and 40 up but I don't know how to make that work without having multiple public ip's. I was thinking that if I did have multiple public ip's on the network I could just divide the computers up so that they are in groups, using all of the public ip addresses for gateways, so that the load is split pretty evenly, but still, there should be a more seamless way to do this, I just don't know what it is. At the rate for business cable internet, 4 lines would probably only cost around 700 dollars a month, which is much better than probably 5 grand a month for several t3 lines.
