Cisco Switching/Routing :: Configuring ASA5510 To Allow VLANs To Internet
Jan 29, 2012
Here is what I have. Windows Domain Controller running DHCP with configured scopes.I have one ASA5510 And 4 HP Procurve switches with VLANS preconfigure from vender.
Here are my DHCP scopes/VLANS:
VLAN1 -Default 10.2.x.x/17
VLAN201 -DHCP 10.2.201.x/24
VLAN202 - WLAN EMP 10.2.202.x/24
VLAN203 - WLAN Guest 10.2.203.x/24
VLAN 252 - MGMT 10.2.254.x/24
Here is how I configured the DHCP Scopes:
Changes needed to make to the DHCP Server (AUSPDC) in order to get things working with the new switches.
1) Configure 3 new DHCP scopes on your DHCP server.
a) scope for 10.2.201.x/24 to serve LAN employees and give them a gateway address of 10.2.201.254.
b) a scope for 10.2.202.x/24 to serve WLAN employees and give them a gateway address of 10.2.202.254.
c) a scope for 10.2.203.x/24 to serve WLAN Guests and give them a gateway address of 10.2.203.254.
I just upgraded and decided to go with the VLAN configuration. None of my VLANS can get out to the internet or each other due to I think My ignorance in configuring the firewall.The PC's are getting proper IP address but they cannot get out or to the other VLANs. I tried to duplicate what is working for VLAN1 but it is not working.
Here is my config.
Result of the command: "show running-config"

I have 2 ASA5510's acting as routers/firewalls, setup on a LAN, each one pointing to a different gateway (different ISPs), and the exact same VLANs set up as sub-interfaces on each of these. Both act as DHCP relays to a Windows Server 2008 DHCP server. All the Trunking has been setup and works. When I Untag a switch port, and point it to whichever gateway?

I would like to configure a 3750 switch port to be able to use two vlans. I know you can do this with a voice and data vlan, but what about two data vlans ? Say I have two devices, one on a 10 subnet and the other on a 172 subnet, but i only have one wall jack for both devices to plug into. So I use a mini switch to connect both devices and connect the switch to the wall jack; and of course this all leads back to one switch port. When I go to enter the switchport access vlan 172 cmd, how would I also make it so the device on the 10 subnet could route out ?

i have one SF300-24p switch where i setup some Vlans and echolife hg8245 ONT router to access internet. the diagram is the following
VLAN1 (Subnet of users) -----> Switch SF300-24p
VLAN2 (Subnet of users) -----> Switch SF300-24p
VLAN3 (HG8245) -----> Switch SF300-24p
VLAN4 (Servers) -----> Switch SF300-24p
i want to control access to internet on VLAN1 and VLAN2 (access on VLAN3), while providing access to VLAN4.My problem is in connecting to internet, i can't find a way to "route back traffic to VLANs 1 and 2 since HG8245 don't seem to provide proper static routing ON LAN interface. Maybe without resorting to changing the HG8245 router ?

I am trying to setup VLAN's in the company I work for and I am almost there but missing the part when the internet works.I have an SG300 as a L3 Router IP 192.168.0.93.I have created VLAN20 and VLAN40 Assigned VLAN20 192.168.2.1 and VLAN40 192.168.4.1
The static routes have been created and a default router going to the Sonicwall firewall at 192.168.0.1.Port 24 is configured as Untagged VLAN1, Untagged VLAN20 and VLAN40 in trunk mode and going to the Sonicwall NSA 2400. [code]
Working to move all 192.168.0.x network off of VLAN1 and move it a management switch.I have DHCP helper on pointing to the DHCP server.Both VLAN's once the DHCP server is configured to Gateway 192.168.0.93 can get an IP from the correct subnet either 192.168.2.x or 192.168.4.x
All PC's are getting a GW IP of 192.168.2.1 pr 192.168.4.1.All test PC's on both VLAN's can ping each other and any server with the correct GW.When I try to ping google.com or open a web page and try google.com it times out.

I have an ASA5510 from which I am using 3 interfaces.
-One interface have the main internet connection router
-One interface is attache to a switch 3750 and has multiple virtual interface configured on it
-One interface has another internet connection router.
What I am trying to do is to have only one of the Vlan using the second internet connection and not the first one.
My idea was to just have a static route who says that on interface VLAN_B (for the special VLAN), all traffic goes to 2nd internet router interface. But it does not route. All I have is a default route configured : on interface Internet1 0.0.0.0/0 goes to 1st internet router interface.

They have a locked Cisco Router which is from the ISP and its confed on a fa 0/0 interface to share Internet access on the network. The ip on that interface is 195.198.11.217 255.255.255.252 and i tried it with a PC (set my personal ip to .218 and entered their dns info (195.67.199.27) and it is working. The question is now. My friend found a 3550 laying around and since the ISP wont let them conf their router he wants to use the 3550 to create 2 vlans with internet access and without access to eachother. Vlan 10 for the desktops and Vlan 20 for the wireless (Moving on to some netgear wireless switches) How would you configure the 3550 for this to work?

i am trying to set up a cisco 2950 with a vlan to seperate all of the pos machines on the network (4 of them) from all other machnes in the building (3 hard wired and wi-fi). i was going to use vlan 1 as a trunk to allow internet access to go from fa0/1 to both vlans (vlan 10 and vlan 20). i have read things about the acl having an explicit deny at the end, so i'm thinking that is my problem. i am testing it at my house before deploying it to the network. i have 1 laptop setup with an ip of 192.168.0.50, and the other is .60. my router is 192.168.0.1. i have the ethernet from the router plugged into fa0/1, the 1st laptop on fa0/2 and the other at fa0/3. before i set the vlans up, i checked the communication by just plugging them in and trying to ping, they could both ping each other, the router and 8.8.8.8. when i finished setting up the test vlans, they could not ping each other(what i wanted) and laptop 1 can ping the router, and 8.8.8.8. laptop 2 cannot ping anything.
the only thing i did was create vlan 10 and 20, set port fa0/2 to vlan 10 and no sh, fa03 to vlan 20 and no sh, fa0/1 to vlan 1 and no sh. then i did switchport mode trunk on fa0/1, and switchport native vlan 1. this seems to be how i was supposed to do it, but it's been a while since i have worked with switches. i'm sure it's simple, but after searching the internet and poring over my cisco books for 5 hours, it is turning out not to be the case. here are some details:
greenhouse#sh int fa0/1 switchport
Name: Fa0/1
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: trunk
Administrative Trunking Encapsulation: dot1q

I have a small cisco switch cluster (seven different 2924, 3524cisco switches) with 3550 as a cluster control which does all the inter vlan routing that works fine.
This cluster is in semi production PBX interop testing lab. This is a closed network without internet access and not connected to our corporate network.However now I have to add this capability so some equipment in the lab can get Microsoft updates over the internet.
I've created a port on a 3550 (fa0/19) and connected it to another network that has internet access. It picked an ip address and when I'm logged in to the 3550 I can ping hosts on the outside network. However I can't ping any hosts on that network from any hosts that are connected to my vlans.I've tried a few different things, but still can't make it to work.
Here is a short version of my 3550 configuration:
!
version 12.2
no service pad
service timestamps debug uptime
service timestamps log datetime
no service password-encryption

We need to give differentiated internet access to three VLANs. Each one of this VLANs is used for totally different purposes, so traffic between the VLANs is not allowed. Each VLAN has its own internet access provided for the data center using one fast ethernet connection.
We're thinking about using cisco 2911 for Internet access, VPN and firewall. I suppose that best option for VLANs is using Catalyst 2960S or a swithing module for the 2911, but these two options are too expensive for us. We're thinking about using swtiches from the SB series (maybe a SG-200).
We're totaly newbies to VLANs so we have many doubts. This are our questions:
1) The 2911 has three on board ethernet interfaces; we have three VLANs and three internet connections, so we need to use HWICs to get three more ethernet ports. That's right?
2) We need three HWICs or there is some kind of HWIC with more that one ethernet interface?
3) The routing solution is to assign static routes in the 2911 for each interface connected to a VLAN through a 2911's interface connected to internet?
4) Simply connecting three different router interfaces with three different switch ports, each one of them assigned to one of the three different VLAN, are we going to get internet access for all devices in those VLANs? or do we need to configure something else like trunking, VSIs...?
5) Can we achieve our goals using the SG-200 switch?
6) We have the chance to use older routers, is this possible? We're specially interested in knowing if a 1841 or a 2801 router could be used for this setup.
7) This is not a production environment so we can use refurbished equipment.

I have a Cisco C3560CG which is running C3560c405ex-UNIVERSALK9-M), Version 12.2(55)EX2.The switch has vlan 1 and vlan 50 configured, vlan 50 should have access to a limited number of host in vlan 1.The following acl has been applied on the inbound to vlan 50:
10 permit tcp 10.16.30.0 0.0.0.255 host 192.168.15.243 eq 137 138 139 445
20 permit udp 10.16.30.0 0.0.0.255 host 192.168.15.243 eq netbios-ns netbios-dgm netbios-ss 445
25 permit icmp 10.16.30.0 0.0.0.255 host 192.168.1.243
26 permit ip 10.16.30.0 0.0.0.255 host 10.16.30.254
30 permit ip 10.16.30.0 0.0.0.255 host 192.168.15.254
[code]....
I sure the above would work, but for some reason some of the packet counter are not incrementing but the traffic is being blocked. But I would like to see the counter increment.Also I have that I may beed to use VACL wouls this be the case?

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.

I use the cisco 871 router as a firewall to my home-office. I have configured two vlans for each seperate port. That is, FE0 configured as VLAN 10 ----> connected to Layer 2 Switch, FE1 configured as VLAN 20 ----> connected to another Cisco Layer 2 Switch,FE2 not in use, FE3 not in use and FE4 is connected to WAN.I got 100Mbps speed from the ISP, but I can see that I only get 50mbps even connected to VLAN 10 or VLAN 20.Does configuring two VLANs on Cisco 871 router divides the bandwidth (to Internet) into half?

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.

I'm using an ASA5510 with AP1130 and attempting to set up a public and a corporate WiFi-network. The corporate one should allow users to authenticate with Radius running on MS ISA for access.
VLAN70 security level 1 (IP-range 10.10.70.0/24) for open guest WiFi.
VLAN71 security level 100 (IP-range 10.10.71.0/24) for corporate users WiFi.
VLAN100 security level 100 (IP-range 10.10.100.0/24) server network (only wired servers).
ASA is gateway at 10.10.70.1, 10.10.71.1 and 10.10.100.1. It is also DHCP-server for VLAN70 and 71.
Radius server is at 10.10.100.5, listening on port 1645 and 1646 for EAP/PEAP and MS-CHAP v2.
I get both WiFi-networks with VLAN 70 and 71 working without encryption, ie. open networks. Traffic flows fine and get network access without problems.
The problem I run into is that it seems the Radius server must be on the same network as the WiFi-clients for them to be able to authenticate with it. That is, I tried to use VLAN100 as the corporate WiFi network and then I am able to connect, authenticate and get network access if I also enable DHCP for that range. However with VLAN70 as WiFi I am unable to authenticate with Radius on VLAN100. It seems the AP can reach the Radius server but clients never get connected and eventually fail with an error.
I can ping the Radius server from the AP. All traffic should be allowed from VLAN71 to VLAN100 in the ASA. Packet tracing shows no errors there.
The switch is a 2960G with the following interface config:
interface GigabitEthernet0/20
description WiFi trunk
switchport trunk native vlan 71

As per my attached diagram, I have three switches (Cat 3560-E and couple of Cat 2960-G)
Each PC is on different vlan
PC -1 on vlan 100
PC-2 on vlan 200
I need to connect PC-1 and PC-2 to the server. Server has no fixed vlan and can be changed.
Restrictions:
1) can’t change PCs vlan assignment.
2) can’t add 2nd NIC in the server.
I’ve tried private vlan but it requires separate physical ports for host and/or community vlan and somehow it did not work. I could be wrong Trunking using dot1q enabled on port 2 on all switches and connection works fine (server to PC-1 or server to PC-2) by enabling switchport access vlan 100 or switchport access vlan 200. However I need port 5 on switch-1 to respond to vlan 100 and 200.

We have 4 1142N LAPs that I want to divide between an internal wireless and a guest wireless network using the controller. Currently all of the APs are on an established internal network, but I want to migrate one over to a test guest network before buying more LAPs to augment the networks further. Currently the port connecting to the WCS from the 3560 switch is configured as an access port using VLAN 10. Whenever I make it a trunk port carrying VLAN 10 as well as the other ports we will be using for the guest and ap-manager networks, I lose connection with the controller. To me this implies that the port on the controller is configured as an access port as well. In the documentation I found for the controller it states that by default the ports are al configured to be trunks, but it appears as though something was changed by the previous tech. All of the APs are connected to other switches, not to the controller itself.
1) How can I get the port on the controller back to being a trunk port
2) Can I use the internal DHCP server for the guest network if the subnet is different than the management subnet, or will I have to use another external server and relay/proxy it through the controller to give guest clients IP addresses?

upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

I have the following config using a Cisco 1921. I am trying to get devices on the the native VLAN to get internet access via the gateway x.x.x.73.Any thing being routed from the other Vlans 15/20/30 can get access, but nothing from an internal IP address. Is there something I am missing.
The Xs replace the same 3 octets for each interface.I am trying to route from VLANs 15/20/30 to see VLAN 5. I have tried a few things, in terms of adding extra ip routes, but can't get anything to work. Each of those Vlans have another router on the other side of them, which I have also tried adding ip routes too, but nothing. One of the routers (Vlan15 is a Draytek 2830). [code]

I am setting up a vm environment for a customer in my lab off site. I have two stacked 3750-x switches, a san, and threes UCS c220 M3S servers for hosts. I am trying to separate the lan traffic, san iscsi traffic, and san management traffic using vlans. The problem is i'm unable to communicate cross vlan with my current config, which I have attached to this post. The only noteworthy things in my conifg is that the ip route 0.0.0.0 0.0.0.0 192.168.83.6 is referring to a switch stack they have on site, that I will connect this stack to using the first two trunk ports on each switch, that I do not have here in the lab. I don't want to cause any confusion in why I have things set a certain way.
