Cisco Firewall :: HP Procurve 5412zl Switch / Multiple VLANs And Gateways?
Feb 9, 2013
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?

Is it possible to have multiple dhcp pools for multiple VLANs? The switch is a 6509 and/or 4506 catalyst. I don't want to use server-based products.

I have:
-Procurve 1810-24G
-Procurve 2520-8-PoE
Router (with Internet Connection) is plugged into port 24 of the 1810.My asterisk server is plugged into Port 1 of the 1810.The 2520 is plugged into Port 2 of the 1810, and all of the VoIP phones are plugged into the 2520.Rest of the office computers are plugged into the remaining ports on the 1810.
After setting up the subnet and assigning an ip to the 1810, everything else just worked out of the box. I would imagine that I should segment and prioritize the network so that the VOIP traffic is isolated and is higher priority from everything else.
I tried playing around a bit, but the phones lost connectivity, so I just defaulted everything back for now.
What would the suggestions be for setting up the VLANS properly to do this?I would also need one of the office PC's (say the one plugged into port 13 of the 1810) to be able to access the asterisk server.Also, would it be more optimal to have the asterisk server on the PoE switch or the main switch?

I need to create a firewalled segment that not only separates hosts from general population, but also from each other. The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible. 1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9
This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).

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?

My problem is that I have a Cisco 300 series small business switch with multiple VLANS each one with an IP address and two or three ports assigned to each VLAN. I have an E3200 wireless router that I want to use to use to share internet on the switch. All of the VLANs are reachable from the other VLANs and I've put a static route on the E3200 so that I can reach the VLANs from a machine connected only to the router. But I can't reach machines on the otherside of the router or get to the internet from the switch.

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've got a cisco asa 5520 and setting up the NAT for multiple DMZs on it.
I want to use PAT on the outside interface.
internally ive created subinterfaces for the VLANs and connected to a trunk port on a switch.
configure NAT for this scenario. I've got only 1 external public IP address.

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.

I have an ASA 5505 with the security plus software and I'm trying to find out how to assign 2 public IPs to the outside interface and have each IP routed to a separate internal VLAN. For example, IP 1 = X.X.X.1 routed to 192.168.1.0 and IP 2 X.X.X.2 routed to 192.168.2.0. I was told this was possible and I've been trying to find configuration examples, but I can't seem to get anywhere and now I'm getting desperate because I'm scheduled to install it this weekend.

how i can configure a second ssid for guest access in our environment. this is our network setup prior to this request: Internet----Firewall (not ASA)---ce520---C1131AG and CME router is also connecting to the ce520 switch. we only have two vlans: one for voice and two for data.
Presently, there is no vlan configured on the AP because it on broadcasting ont ssid and wireless users gets IP from a windows DHCP server on the LAN. the configuration on the ce520 switch port for the AP and other switches say access vlan is the DATA vlan which automatically becomes the native vlan for all trunk port connecting the AP and other Stiches to the network.
Now with this new requirement, i have made my research and i have configured the AP to broadcast both the production and the guest Vlans. The two vlans are 20-DATA and 60-Guest. I made the DATA vlan on the AP the native vlan since the poe switch is using the DATA vlan as native on the trunk ports. I configured the firewall to serve as DHCP server for the guest ssid and i have added the ip helper-address on the guest vlan interface on all switches while the windows server remains the dhcp server for the production DATA Vlan. I have confirmed that the AP, switches can ping the default gateway of the guest dhcp server which is another interface on the firewall. I can now see and connect to all broadcasted ssids but the problem is I am not getting IP addresses from both the production dhcp server and guest dhcp server when i connected to the ssid one at a time. My AP config is attached below.
Do i need to redesign the whole network to have a native vlan other nthan the data vlan? Does the access point need to be aware of the voice vlan? Do the native Vlan on the AP need to be in Bridge-group 1 or can i leave it in bridge-group 20?

we're running some HP ProCurve 2520's (24 port PoE for desktops/phones) and 2510's for our server racks. The CPU's are a bit weak from what we can tell and sometimes end up with issues on them. The specs on the EAS series look like a decent jump compared to the older HP's. However I've never worked with these ever.
My other option is to go back to Cisco. However to make it fit our budget, we have to dump gig switches for 10/100 + PoE. Which isn't really a major issue on the desktop switches. We'll naturally put gig versions on the server racks. I like our ProCurves, however they cause issues from time to time.
I've also considered going back to Adtran, however I haven't kept up with what they have to offer. I'm tempted to play it safe and go the Cisco route. We're using ASA5510's active/passive for routing/firewall (gig versions).

My current switch layout at work is very basic and offers no redundancy. I'd like to at least setup redundant core switches, so that if any of my switches would to fail, it would result in a smaller number of systems affected.
Current Core Switch: HP Procurve 3500yl-48G (3500yl-24G as cold spare)
Internet Switch: 3com (forget model)
User distribution switches: 9 Planet 10/100 Layer 2 Managed switches, and 2 Dell Powerconnect 5448
Server switches: 5 Procurve 2810-24Gs (1 in each server rack)
In addition, we have 50+ site to site VPNs using different 192.168.x.x subnets across 2 different VPN concentrators, several routers, and a pair of MPLS's.My first step to improve speed and reliance was to reconnect the user switches. The old distribution switches were daisy chained, and all users 120 users were on a single 1GB port on the core switch, and if switch 2 of 11 failed, I'd have 10 switches knocked out of the network. I've since connected them directly to the core switch, and the users have noticed the improvement.
I'll try to get a diagram, but it's basically a large hub and spoke. Each and every switch is connected directly to the single core switch. All of the internet sources are connected directly to the 3com and are on separate VLANs which are then connected to the core via a trunk, which then handles the routing. Currently, I'm using less than half of the ports on the current core switch, so I should still have enough ports on the 24G to at least maintain the critical systems. Each server switch is trunked to the core, as is the internet switch, but the user network is not (but probably should be). Instead they are connected via simple untagged uplinks.
I absolutely cannot afford new equipment right now, so whatever I do will require reusing existing equipment. I'd very much like to increase the bandwidth from the server switches to the core if at all possible. Is there an easy way to configure and Active-Active setup that would improve bandwidth? Or would It be active-passive and require a 2 port LAG on the 48 port (for speed), and a 3rd port for the 24 port (for redundancy).
NOTE: With any luck, we'll be dropping our analog phone system and replacing it with VOIP sometime within the next year. So I should be getting some extra budget to replace the distribution switches with POE. Until then, I'll have to live with my crappy Planets.

I have 2 ASA 5505 firewalls and 1 cisco 3560 switch.
One ASA 5505 firewall and cisco 3560 switch located at SITE-A. Another ASA 5505 firewall located at SITE-B.
Below is the my connectivity:
Site-A IPSec VPN Site-B
cisco 3560 <----------------------------> ASA 5505<------------------------------------------------------------------------------------> ASA 5505
I planned to create 5 vlans in my cisco 3560 switch. these 5 vlans needs to have internet and needs to access Site-B.
I will write on dafault route to firewall in my cisco 3560 switch. Is ASA 5505 supports this scenario??? If it is then how to configure ASA 5505 firewall.

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]

A CISCO 3750-X stack with several VLANs and many ACLs applied to the virtual interfaces. Intervlan routing is on. Connected to this stack are VMware hosts and with about 500 VMs.We started using the ACLs to allow connectivity between VLANs to specific hosts and it has grown to thousands of lines. I personally do not think this is good for the switch and believe the switch was not intended to be used for that security feature.
- Does it make it sense to add an "internal firewall" between the CORE ROUTER AND THE 3750-X SWITCH STACK ?
- Do you recommend any other way?
- Any recommended CISCO resource/white paper to read about best practice

Currently in our environment we have have two buildings with an ASA 5520 in each and a core stack of 3750's in each building. I am currently working on a network segmentation project and am thinking of adding another stack of 3750's in each building to add more redundancy to our network. This will allow our access layer switches to have a trunk to each stack and prevent an outage if one of the links or stacks were to go down.
My question is how I would set this up on the ASA end of things while using a common subnet and HSRP on the 3750's. I understand how to use HSRP and STP on the switches to achieve this on the 3750 end of things. I saw you can do etherchannel on the ASA with 8.4 but how does that work in a failover situation?

I have a 5412zl 10.215.x.x/16 Most of the connections on this switch are on vlan1. B9 is the port which is connected to a Cisco 2821 Router. The port on that end is GE0/1. The port on the cisco side is not a trunk but configure with an ip of 10.215.1.30/24 Its part of a some ip access group. The network that i now sit on is a 172.x.x.x/24 (behind cisco router, about 3 hops to that main 2821)We current have a system on my side that talks to a server on the 10.215. that has no issues. I'm trying to access some switches on the 10.215. and have had no luck reaching them.
Here is the access list that i found that port is configured to use:
permit ip 10.215.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 172.14.0.0 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 172.14.0.0 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.215.0.0 0.0.255.255 192.168.20.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.20.0 0.0.0.255 I would think the first permit would allow me to get through to the 10.215 side but maybe i need to set something up on the hp size to let it know how to get back? I'm very new to this stuff.

The network topology is like this. Router with DHCP_Server on it.
VLAN 10
VLAN 20
VLAN 30
My question is how to configure the router so that all devices on all 3 VLANS can obtain IP from the router. I've tried to enable proxy arp on all interfaces and create sub interfaces and trunk them to their appropriate vlans, but I can't specify the gateway on all trunked sub interfaces because I get a warning that addresses overlap. Then I tried to set access-group on all sub-interfaces and still doesn't work.

I recently set up a Cisco 881 to cover a small business network. The router is currently set up and working as expected. We recently decided to move to VoIP phones and here is where I'm running into some issues.
First an overview: We run a network with a cable internet WAN connection, this connection is DHCP, however we have a static IP through our ISP. We also have a block of 30 additional IP addresses for one to one mapping as we need them. The new VoIP system is being run over T1 lines throughout the township (we are a municipal organization) and the VoIP system is being run to about 5 buildings in the township.
This brings me to the topic of VLANs. As the phone engineer explained it to me, there is a network set up over the T1 that allows the VoIP equipment to talk to one another and operates all of the VoIP phones on one network. The equipment that is being installed at our building connects to the network over the T1 and "talks" to the other equipment on the network. The engineer wants to create a VLAN and run it on ports fa1 and fa2, with the fa2 port being connected to the actual "MPLS" (their term) that connects to the T1 and into the cloud, and the fa1 port connected to the internal phone switch.
TLDR; The problem is this: When we attempt to set up the VLAN on ports fa1 and fa2, we have no connectivity with the other units in the external VoIP cloud. Pinging while directly connected to the "MPLS" yields successful pings, while pinging from the router with the "MPLS" connected to fa2 yields failures. I'm going to post the running config below, I feel like what we're doing should be working. I asked around about subinterfacing, but others seemed to think this was not necessary.

I am having problems accomplishing these tasks with my new SG 200-18.
I have a LinkSys WRT54G2 connected to port 1. I would like ports 2-8 to be in one VLAN with access to the Internet and to be able to share their printers, hard drives, etc. with other computers on ports 2-8. I would like each of ports 9-16 to be on a separate VLAN with access only to the Internet and no other ports on the switch. I would like to be able to manage the switch from any of the ports 2-8.
After I create the VLAN 1009 (see screenshot below), port 9 can browse the Internet and cannot see the other ports on the switch which is correct. However, ports 2-8 can no longer access the switch at 192.168.1.20 in order to manage the switch.

I have two Cisco 1300's acting as bridges only. I have created an infrastructure ssid on VLAN 2 and assigned this to the radio. I am carrying multiple VLANs between the bridges (using subinterfaces on the fastethernet and radio ports).I have enabled WPA-PSK, but how do I check that this is being used between the bridges? Also - I have a switch connected at each end of the bridge. When I make VTP changes, the remote switch does not pick these up - is this because VTP goes over VLAN1 regardless of the Native VLAN (2 in my case)? Do I have to carry VLAN1 over the bridge to get VTP working, or is there an alternative solution?

I have a RV180W and a EnGenius EAP350 Access Point. The EnGenius supports multiple SSID's and VLAN tags them. If port 1 on the RV180W has VLAN 1 untagged and VLAN2 tagged, any connection to the EnGenius always gets an IP from the VLAN 1, even though they are connected to the SSID which is tagged with VLAN2.
