Cisco VPN :: 5510 IPSec VPN In Security Context / Shared Interface Or Not
Feb 17, 2013
I have at the moment an ASA5510 pair in Multiple Context configured. Everything is ok, but we use til now only ACL features.Now I would be interested in configuring 2 contexts, with IPSec VPNs. One VPN per context. But I cannot find any information if it would be possible to use a shared interface for both contexts. My wish would only be to spare public IPs.If I have to configure 100 VPNs in 100 contexts, do I need 100 public IPs ?
ASA 5510 security plus edition will it support active/active failover. and does it support context with securiyt plsu edition. and how many default context do we get with asa 5510 security plus edition.
I currently have an ASA 5510 setup with Dual homed ISP's and a remote access IPsec VPN setup to terminate at either interface. The first interface is named Outside and the second is simply called Outside-2. When outside the company(such as at home), the VPN client will connect on the Outside-2 interface and work normally. The problem is while testing on our DMZ, the VPN Client will not connect on the Outside-2 interface. It will try that interface fail to connect and then connect to the backup Outside interface. This isn't a huge concern because it still connects, but if we were ever to get rid of one of those connections, it would be nice to reliably test from our DMZ.
i configurated ipsec vpn at cisco asa 5510. all them are working very well. now i want to change ipsec remote vpn to L2tp over ipsec.i have router, asa and 3750 switch. all nat translation are done at router , ipsec vpn configurate at asa.
this is my ipsec configuration. this is working config. as you see i do static nat asa outside ip for vpn at router. now i want l2tp over ipsec. before i do it i have some question
1. must i do static nat port udp 1701 for l2tp over ipsec vpn? can i write access list at asa to open port 1701?
2. can i remove this static nat or i can not be change anything.is this nat is true for l2tp over ipsec vpn?
3.as you see user authentication from radius server at ipsec vpn. i also want this is same as l2tp over ipsec vpn..
4. i think that i must be add this addtional config. is this true? tunnel-group DefaultRAGroup ppp-attributesno authentication chapauthentication ms-chap-v2
is this config enougth for l2tp over ipsec vpn?? what is addtional config i need?
my inside ip 192.168.10.156 my public ip: 85.x.x.x my peer ip : 62.x.x.x
the project is that:the remote site want the interesting traffic like that:
source ip 172.16.1.104 can access destination ip 10.0.154.27
my inside ip is 192.168.10.0/0 and i can not to change it 172.16.1.0/24 and i can not to add this ip at my network.i do that way but i can not test it.
What are the new features added or going to be available on the 8.5 release on the ASA. Would this release "finally" support VPN on multi security context mode.
By the sounds of things looks like every other major vendor supports this feature except Cisco.
I had lots of trouble creating an IPsec VPN tunnel between a SRP527W (FW 1.01.24 (003) Sep 7 2011) and 2811 (Version 12.4(25e)) Router.The message on the 2811 was "IKE message from x.x.x.x failed its sanity check or is malformed". The reason was the password complexity (or length, which I did not try out). The password I used was "$SIMA$B3nlXySl-q+C&PnI" which is not in use any more . Now I use a password without special chars and it works fine.
I think this is a bug on the SRP527W, because it works fine with an old 836. How to report a bug to cisco? I'm Cisco SMB partner, but I'm not allowed to create a TAC service request.
I have a ASA 5510 and planning to implement multiple context in a 2 tier security level and vrf-lite. meaning I have 2xASA facing the internet and below that a 2x3560 switch for our extranet and below that is another 2xASA for intranet. See diagram below. In this kind of network I want to know how it would impact the total throughput and resources of the ASA using multiple context?
I need your support for upgrading the Security context license on 5550, at present we have 5 Security context license installed in ASA but we want it to increased till 10 conctexts. I want to understand if we need to get addtional 5 Security context license or 10.
I have a active-active setup with 2 cisco asa 5585x running 8.4 - the boxes ahve each 2 sec context's build-in - which gives 4 sec context in the cluster. I have 2 x 5 extra licenses (2 x ASA5500-SC-5) which I haven't applied yet - will this give me a total of 10 or 14 security contextes? I am a bit in doubt because if I only get 10 sec contextes in this cluster then could I instead get a single 10 security context license (1 x ASA5500-SC-10) and add this - hereby I would get 12 then.
ASA have two context groups say admin and and x. Its interface gi0/2 has 6 subinterfaces from 1 to 6.3 subinterfaces ----0/2.1 to 3 are in admin and last 3 are in context x.when i went to system context it does not show where interface gi0/2 belongs to it only shows up up.how can i find which context group physical interface gi0/2 belongs?
On our ASA 5510 we have two security contexts. After opening ASDM I can see and manage admin context, but cannot see second context. I can do changes to second context via CLI but as probably you know it's easier and quicker doing it via ASDM.
My corporate internal network is currently fire walled by an FWSM module on a 6513 switch. We have each security zone (we have eight) assigned to a FWSM context and have ACLs set up between the contexts and the enterprise LAN/WAN. Is it possible to support fire walling between these zones within a single security context? The reason I am asking is that we would like to purchase a second FWSM for use as a standby, but do not want to cough up the ~ $12K for the context license. We will ultimately be transitioning to ASAs for internal security, so do not want to spend more than we need to.
Is it possible to use 1 or 2 of the 4 gigabit ethernet ports from one ACE straight into the other ACE for redundancy? So ACE_01 gig0/4 to ACE_02 gig0/4.If so, is it a case of just having the layer 3 config instead of trunking etc..Also - is it possible to create a context within the same vlan as the Admin context?
On my production environment I have a firewall with already two contexts defined (15% of CPU used) and I want to add a new one.
This context is going to use the same interfaces as the others contexts. When I will enable the context, can I have some sort of repercussion on these two context ?
I have two ASA 5510 in an Active/Active failover configuration; On the first ASA I have a license for five security contexts, on the second one I have the default two. On the pair I configured seven security contexts and everything works as expected; so far so good. Let's suppose now that the first ASA (the one with the license for 5 contexts) goes up in smoke; all the contexts migrate to the surviving firewall and life is still good. But what happens if, for some reason, I need to reboot the second ASA before the first one is repaired? My guess is that it will come up with just its own license for two contexts and that I will not be able to operate all my virtual firewalls.
use of a pair of ASA 5585's in active/active mode with a shared outside interface.Last time I did this was with FWSM, there was a restriction where all contexts that share an outside interface have to be in the same failover group.Does this apply also to the ASA? My thought is that it will, but I am unable to find that in any documentation.
I have attached a pdf of an example of a FWSM configuration with shared interfaces. Now what I dont get is (please refer to the link) url...Is there any difference between the natting that they have done on page B-4 on Context A.as opposed to configuring a static NAT for processing traffic to correct context nat(inside,outside) 209.165.201.0 10.1.2.0.The other question is on page B-2 (diagram) Context A has a customer A network linked to the inside interface. Is it possible to put a default route towards that "Network 2" cloud and restrict traffic from the 6509 switch towards the context A?
I recently picked up two ASA5510s (ASA5510-SSL50-K9 & ASA5510-SEC-BUN-K) with intentions of creating an Active/Standy configuration. I'm receiving the error message "Mates' license (2 SSL VPN Peers) is not compatible with my license (50 SSL VPN Peers)", but I was under the impression that I didn't have to buy idential SSL VPN licenses post 8.2 in an Active/Standby configuration. am I missing a step that enables the license transfer(sharing?) feature to work correctly before the failover will build correctly?
I have a situation where we have a single DMZ server currently statically forwarded to a single public IP. TCP ports 80, 443, 8080, 8500, 53, and 21 are open to this server via an access list.
However, we have added an additional server to the DMZ, and because our web developers did not communicate with me beforehand, we are forced to use the same DNS name (thus, the same piblic IP) for this server. This server only needs traffic on TCP/8800 forwarded to it.
I am using ASDM 6.4 for configuration of this, as I am required to take multiple screen shots of the procedure for our change control policy.
My question lies in the reconfiguration of NAT/ PAT. Since our current server has a single static NAT to a single public IP, it is simply natted for "any" port. I understand that I can add the new server as an object, and only PAT it on TCP 8800, but will I then have to go back and reconfigure the first server multiple times for PAT, or will the ASA notice the specific PAT, and forward 8800 to the new server without affecting the existing "old" server?
It appears ASDM will not allow me to put multiple ports into a single network object. I am assuming I will need to add 6 separate object translations for the "old" server based on TCP port, and 1 object translation for the "new" server, correct?
How to place security + a password on a folder that is shared on a local area network. i don't want other users to access the contents in the folder since we are all on the same local network.
I have configured Ipsec vpn tunnel beetween two routers (from site A to site B) over untrusted internet connection by cisco 3825 routers and i can successfully access both of this routers. But now i need to access internet on site B router sitting on site A router. So that if i run traceroute from A site machine then the gateway by which internet passing through shows the ip of site B.
The Architecture of our both site routers :
Site A 10.1.11.0-----Router A 172.18.12.1-----VPN tunnel----Router B 172.18.12.2-----Site B 10.4.11.0

I'm actualy trying to bring two IPSec VPN on only one interface. I've successfully created a tunnel between Par and Barcelone and between Par and Mad. But I can't create it between Barcelone et Mad. We have a cisco ISR1921 in Mad and Barcelone, and a Netgear in Par.
How to make a Cisco 881 router finally work. I have the following configuration:
Current configuration : 2964 bytes ! ! No configuration change since last restart version 15.1 no service pad service timestamps debug datetime msec service timestamps log datetime msec
[code].....
As much as I understand, the VPN tunnel is active.I can access the Internet, but I cannot access anything through the VPN tunnel.
i have started managing a asa 5510 firewall which is already having 10 ipsec tunnels , the problem i am facing is they are configured as "ipsec vpn map"
i have attached sample config, i am finding it difficult to understand the parameters used in each tunnel as the configration seems bit complex to me, how it works .
I have a network with Two 3800 Cisco Routers as Central and many Cisco 2811 Router as Branches. Now I set two Tunnel on each router connection Interface FastEthernet from each 2811 to SubInterface Fastethernet on 3800. I set OSPF as Routing Protocol and I configure QOS on Tunnel connections. Then I have a safe connection with backup connection between 3800 Router and each 2811 Router. Now I want to set VPN with IPSEC and Certification Authentication with CA Server for Security all connection. I set IPSEC and ISAKMP and Certificate on each Router and Set Dynamic VPN on Cisco 3800 Router and Static VPN on each Cisco 2811 Router. Now when if I configure tunnel with Crypto map, it works correct and all packets are encrypt. But if I try to set crypto on physical Interface(because I want to set qos on tunnel then protect packets on physical interface) however all packets are routed but crypto and encrypt d o not work. Set qos on tunnels and crypto on fastethernet interface.
