Cisco VPN :: How Many VLans ASA 5505 Security Plus Support
Nov 18, 2011
i have asa 5505 adaptive security plus. and i have only 3 vlans . outside , inside , DMZ restricted.so it's working fine but i want to connect to my inside another private network, or do i need to buy License.and how i can activate the license key.
I am buying ASA 5505 with security license. It says it can support 20 vlans does it support 20 vlans by allowing to create subinterfaces? As it has 8 physical ports only?
I am working on my CCENT after getting my A+. I have an old 3600 router and I am following CBT Nuggets to configure it. CBT Nuggets seems to have an IOS that supports VLAN and IP Addresses and it looks like mine only goes up to Token Ring so it doesn't mirror the instruction. I know it's an old router but is there a software release (like the 12.4 maybe?) that would allow me to follow the CBT Nuggets more accurately so that I can set the switch up for IP Addresses and VLAN instead of limiting me to token ring?
On an 887VA running 15.x IOS, is there a way to support both public and private addresses on inside vlans? The outside interface is public static ip, so the requirement would be to not nat anything if coming from inside vlan10 but nat if coming from inside vlan20.I didn't think this was possible since the outside interface would have to use an outside nat command that would not be ignored for traffic coming from vlan10.
routing between VLANs on my ASA 5505. I am very technical system wise, but my knowledge of routing and switching is very shallow.
What I am trying to accomplish: Small lab environment with basic services split onto two seperate VLANs (such that DHCP would need a relay on the second VLAN to deliver leases). No external network connection as of right now (so no Internet).
My current configuration: Cisco Catalyst 2960 As you can see below, the two VLANs I am trying to set up are vlan101 (10.100.100.1) and vlan102 (10.100.101.1) Code:
I have a ASA 5505 that I test with which originally came with the Security Plus license. I recently erased flash and loaded the latest asa841-k8.bin version of IOS along with asdm-642.bin. Everything booted fine and came up as it does when freshly wiped however I noticed that i was now only running a base license. If I issue the sh activiation-key command, I noticed the following messages (full output is at the bottom):
The Running Activation Key is not valid, using default setting ...... This platform has a Base license. ...... Failed to retrieve flash permanent activation key
Did I somehow kill my Security Plus licensing when I did the erase flash? If so how do I recover it?
ciscoasa# sh activation-key Serial Number: JMXXXXXXHU Running Permanent Activation Key: 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000
The Running Activation Key is not valid, using default settings:
Licensed features for this platform: Maximum Physical Interfaces : 8 perpetual VLANs : 3 DMZ Restricted Dual ISPs : Disabled perpetual VLAN Trunk Ports : 0 perpetual
[code]...
This platform has a Base license.Failed to retrieve flash permanent activation key.The flash permanent activation key is the SAME as the running permanent key.
I have an ASA 5505 and I have the three regular vlans, outside, inside and dmz. The best would be only have outside and inside and skip dmz, but without explenation there is not possible to have more then two clients in whats now dmz because of a mac filter on third party device.
So as security is concerned dmz and inside is equal, one to one and there should be full access between them. I ran the wizard and said that the only way traffic not should be possible to flow is from dmz to outside.
In the NAT rules the onle rule is global (outside) 1 interface nat (inside) 1 0.0.0.0 0.0.0.0
But traffic from one way or the other dmz to inside, og inside to dmz it says in log
3Dec 06 201215:38:39305006172.17.6.1053portmap translation creation failed for udp src inside:192.168.6.102/49358 dst dmz:172.17.6.10/53 From documentation I have an image with network drawing from documentation. What do I have to do allow traffic btween inside and dmz, both ways.
I have a 5505 with Base license running ASA software v8.4(2) that has been working happily for a while with an inside and an outside VLAN.
The outside has a single statically configured public IP, and I have a number of static NAT rules to expose a few internal servers as well as Dynamic-NAT for all devices on inside to gain access to the Internet... the main bits of the config are below:
I now have a requirement to add a "dmz" VLAN for guests to have access to the Internet using a dedicated wireless AP, but not to any of the inside resources. As the ASA has a base license I have configured "no forward interface" to the inside vlan, which suits the purpose fine
interface Vlan12 description Used only for guests access to the Internet - no access to the corporate resources no forward interface Vlan1 nameif guests security-level 20 ip address 192.168.2.1 255.255.255.0
My problem is that when I try to add NATing from the dmz to the outside I get a:
ERROR: Address a.b.c.d overlaps with outside interface address. ERROR: NAT Policy is not downloaded
Having had a look at the ASA Configuration guides, all the examples I can see with several "internal" VLAN's being NAT'ed use one external IP per VLAN - is this a feature/restriction of the ASA software? Are there any workarounds? Or is the overlap in the error message really about the current NATing to the inside VLAN which is done on the "any" 0.0.0.0 subnet - would the following then work:
so I look up ASA5505 licensing and for VLAN support see: 3 (no trunking support)/20 (with trunking support)*
I need 3 VLANs...inside, outside, and DMZ..but when it is creating the third (DMZ) it says I am only allowed to have 2 VLANs and can only create the third if its set to not forward traffic. ?
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've got an ASA 5505 with the Security Plus license that I'm trying to configure.
So far I have setup NATing on two VLANs, one called 16jda (VLAN 16 - 10.16.2.0/24) and one called 16jdc (VLAN 11 - 10.105.11.0/24).
From each subnet I am able to connect to the internet, but I need these subnets to also be able to talk to each other.
I have each VLAN interface at security level 100 and enabled "same-security-traffic permit inter-interface", and I have setup static NAT mappings between the two subnets, but they still can't communicate.
When I try to ping there is no reply and the only log message is: 6 Aug 21 2012 09:00:54 302020 10.16.2.10 23336 10.105.11.6 0 Built inbound ICMP connection for faddr 10.16.2.10/23336 gaddr 10.105.11.6/0 laddr 10.105.11.6/0
I have ASA 5505 Firewall with security plus license, I configured two V LAN 1 and V LAN 5 as my inside V LAN for different sub net, i need to route the traffic between this two V LAN's through ASA. I configured
int vlan 1 nameif inside Security level 100 Ip address 172.16.100.1 255.255.255.0 [Code] .........
The problem is i am not able to ping other sub net, for ex my PC is in V LAN 1 not able to ping 192.168.22.1 ... For troubleshoot i type debug icmp trace while pinging other subnet

I have 2 Vlans with seperate networks and want to create a route between one server in vlan 465 to another server in vlan 436 via port 80.Vlan 465 has a ASA 5505 inside that IP address 89.254.12.35 will be initiating the connection to address 10.200.1.213.
-Vlan 465: server address 10.200.1.213 -Vlan 436: server address 89.254.12.35
However for extended security I would like to restrict the firewall opening to an IP to IP opening.
I have a ASA 5505 with the security plus license. I have 7 vlans, 2 are guest vlans for wireless and wired connections. I am allowing traffic from the guest vlans to any with the http & https protocols I have ACL's in place before the allow all rule that do not allowed traffic from the guest vlans to the other vlans. Is there any way to have all traffic from the guest vlans to always go to the outside interface for the http & https traffic in stead of trying to go to the other vlans first, I know I have the ACL's in place to prevent the traffic but if I would feel better if I had this in place as well.
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.
I have set up a scenario for a small business and have some questions about how to manage the access between the VLANs. Is there is a better / another way to do it. See the attached picture for the topology / info.
My question is: My switches is set up with x numbers of VLANs and a routed port (no switch port) to the ASA for internet connectivity. How is the best (or only??) way to manage the access between the VLANs? Is it ACL's on the switch?
And by "managing access" I mean VLAN 50 (public WiFi) only have access to the internet, only management servers have access to management VLAN, Client VLAN only have RDP access to server VLAN and so on. Is there any way to do this in the ASA (or add another (gigabit) router to the topology)) or it the only way to have lots of ACL's on the switch itself? I have thought about "router on a stick", but then I imagine there will be a bottleneck between the switch and the ASA?

One of my client want to upgrade its already installed ASA5540-bun-k9 by adding CSC-20 Module. As per below link CSC-20 is supported with ASA5540. but for any reason the ASA5540 bundle option with CSC Module is not available that create confusion.Will CSC-20 Module work with ASA5540-bun-k9 [URL]
My company has started the migration from Windows 2003 to 2008 R2. Will my ACS Express boxes (currently running 5.0.1) ever have an upgrade option to work with 2008 R2? Do I need to trash the ACS Express appliances for some other solution?
I need my ASA 5505 to support ESP-AES-128-SHA on 2 dynamic clients, one with PFS and another without PFS. I add 2 dynamic maps like this. [code] Now the client without PFS can be connected, but the one with PFS cannot.How can I set the dynamic maps so that they can support both clients at the same time?
we have installed nac for our customer and it works fine ,but the customer want the change the version of kaspersky antivirus from 6 to 8 end point security ,when we have try this the nac agent does not find the antivrus on the the workstation . i want to know if this version of kasoersky (end point security ) is supported by nac ,if no is ther a solution to make it works with the NAC .
I am going to update my Windows Small Business Sercer 2003 to 2011.I currently have an ASA 5505 with the IPS installed on it. I am reviewing the migration procedures from Microsoft. Within the procedure it asks if the firewall or router supports UPnP. Does my ASA 5505/IPS support UPnP?
Just want to check out, does the non-Microsoft based OS client OS (Example: MacOS, Ubuntu, Android) support anyconnect v3.0 And also if my RADIUS server is host using window server 2008 Network Policy Server (NPS) component, can this doing the 802.1X authenticating?
I recently got a refurbished external (USB) wireless adapter by Netgear. It's the WNA3100 but who knows what they did to it while refurbishing it.
I tried using it to connect to the wireless network at my university, and I got the above-displayed error. So what's the deal? This RADIUS thing is not a new technology, right? So any modern wireless adapter should be able to handle it. Why would this thing not support it?
Secondly, if it doesn't work, that's alright. I need a second wireless adapter anyway, so I could use this one at home where the RADIUS thing is not an issue. But how do I make sure this does not happen again with another one that I buy? I can't seem to find anywhere in the specs anything about this compatibility. For instance, I believe I want to get this one next:URL
Does the ASA 5505 will allow the addition of a 2nd external link to its configuration? I know the device is capable of Redundant or Backup ISP Links, but that’s not what I need. I will have two different links for two different purposes. Currently we are using the ASA 5505 just for Internet access, so only the ISP link is connected, very basic configuration. We are planning a connection to a client’s global (MPLS) network and we need to be protected against any traffic coming from that network, ergo we need to use a firewall for connection to that external link.Now with the final configuration the Internet traffic must keep being routed to the ISP link, and some other traffic must be routed to the new external link. Can the ASA 5505 be configured for this scenario?
one of my router are scanned by Foundstone and get an alert :
""The SSH2 protocol specification requires that a SSH2 server support the diffie-hellman-group1-sha1 key exchange algorithm. This key exchange algorithm is considered strong, but faces a potential weakness in that the same prime number is used for all key exchanges."
SO wanna check if cisco SSH2 can support the diffie-hellman-exchange-group-sha1? If yes, which IOS version required?
I have a customer that wants to purchase an ASA 5510 security plus to terminate client VPN access for an external support team. The customer claims to want URL content filtering/proxy which leads me to suggest a CSC SSM 20 plus module. But upon further conversation, he mentioned wanting IPS. In this case, the customer does not seem to know the difference between the URL content filter/proxy and the IPS and uses both terms interchangably.
1. What would you suggest in your expert opinion would be the best module to get for this customer? IPS or CSC
2. If I go with the CSC module, where can I find good documentation on how to configure it and get it up to date?
3. does the CSC module provide any web proxy functionality?
WE have to deploy ASA5585 in between User vlans & server vlans. we have to find all the ports that needs to be opened on firewall. any tools to do same.
