SNMP per-ipsec tunnel bandwidth monitoring
Whish oid can be used for monitoring bandwidth (bps, kbps...) per ipsec tunnel, assuming there is now logical tunel interface configured?
ios supports CISCO-IPSEC-FLOW-MONITOR-MIB, but cannot find oid in ftp://ftp.cisco.com/pub/mibs/oid/CISCO-IPSEC-FLOW-MONITOR-MIB.oid.
Tnx!
Hi Spr,
Check out VPNTTG (VPN Tunnel Traffic Grapher) is a software for SNMP monitoring and measuring the traffic load for IPsec (Site-to-Site, Remote Access) and SSL (With Client, Clientless) VPN tunnels on a Cisco ASA. It allows the user to see traffic load on a VPN tunnel over time in graphical form.
Advantage of VPNTTG over other SNMP based monitoring software's is following: Other (commonly used) software's are working with static OID numbers, i.e. whenever tunnel disconnects and reconnects, it gets assigned a new OID number. This means that the historical data, gathered on the connection, is lost each time. However, VPNTTG works with VPN peer's IP address and it stores for each VPN tunnel historical monitoring data into the Database.

Monitoring IPSec Tunnel Bandwidth Utilization
We have a Cisco ASA 5520 supporting multiple VPNs - both remote-access and Lan-to-Lan. We would like to monitor the bandwidth utilization of the IPSec Lan-to-Lan tunnels. How can we do that?
Thanks,

Is it possible to build two different L2TP/IPSec tunnels per subnet or per user?
Dear colleagues
I wondered whether anyone could help with this one.
Is it possible to build two different L2TP/IPSec tunnels per subnet or per user on a Cisco router or any other third party manufacturer? The idea behind is to allow different access to resources to different support technicians. Your help is much appreciated.Sure, the ASA can use LDAP/AD information to select what access list should be applied for that specific user or group of users logging into the VPN. You can use whats called DAP or just LDAP Attribute Maps.

The tale of two IPSec Tunnels...
I'm trying to set up an ipsec tunnel at a particular site, and I am just stumped at this point. I have two sites I'm working with, a test site on my bench and the other actual site at another location. Both are ASA 5510's, both are running ASA v8.2(5). The test site has a 3560 off of it, and the production site has a 3750 stack off it. I don't think that part should matter, though.
I used the wizard to create the ipsec configuration on both devices, test and prod, and used the same naming on both to help compare. The test site connects and I can ssh to the 3560 behind it just fine. The production site, however, cannot connect to that 3750 or ping it to save my life. I've poured through the configs on both, and although there are just a couple of differences, the two ASA's are pretty close in configs.
At first I thought it was an acl issue, but I've filtered the logs by syslog id 106023 to watch for denys by access group. When I try to connect to the 3750, I get absolutely no entry in the log that anything is being denied, so I figure that's not it.
Then I thought it may be a routing issue. The one difference between the two sites is that the test site is using eigrp to disperse routes between the asa and switch, while the production site is using static routes. But I also didn't think that would've mattered, because on the static route switch I even put a static route in there to the vpn network which didn't make a difference.
I've also run packet traces on the firewall when doing a ping, and on the test siteI see echo requests and replies. Oon the production site I only see requests, no replies. My encap counters don't increment during pings, but the decap counters do, which make sense.
Other things to note: The test site that works also has a site-to-site vpn up and runnning, so you'll see that in the config as well. Client is Mac OS X 10.6.8, using the Cisco IPSec Config.
I'm hoping someone can look at my configs and tell me if they see anything I'm missing on them that could help solve my problems. I'd appreciate it! Thanks

AP registration over IPSEC Tunnel(ASA)
Guys,
I have my WAP sitting behind ASA and have ipsec tunnel between ASA and router.below is the topology:-
WAP>>ASA<<< IPSEC TUNNEL>>> Router<<<WLC
Recently we have replaced router with ASA 5505 for security reasons and since then WAP is not able to registered to WLC. we have VPN tunnel up and working. Even WAP is able to ping to WLC ip address.
Do we have any special configuration in my ASA considering my above topology. I can confirm that capwap and lwap ports are opened in asa.
Please let me know if some one has faced this issue before.Hi,
I hope you have already allowed the below mentioned ports as per your requirement.
You must enable these ports:
Enable these UDP ports for LWAPP traffic:
Data - 12222
Control - 12223
Enable these UDP ports for mobility traffic:
16666 - 16666
16667 - 16667
Enable UDP ports 5246 and 5247 for CAPWAP traffic.
TCP 161 and 162 for SNMP (for the Wireless Control System [WCS])
These ports are optional (depending on your requirements):
UDP 69 for TFTP
TCP 80 and/or 443 for HTTP or HTTPS for GUI access
TCP 23 and/or 22 for Telnet or SSH for CLI access
Also if it goes over the IPSec VPN, MTU size for the path between AP and WLC should be of 1500, if it has the lesser MTU, then communication fails.
Can you get me your WLC and ASA OS versions?
Regards

Cisco ASA 5505 IPSec tunnel won't establish until remote site attempts to connect
I have a site to site IPSec tunnel setup and operational but periodically the remote site goes down, because of a somewhat reliable internet connection. The only way to get the tunnel to re-establish is to go to the remote site and simply issue a ping from a workstation on the remote network. We were having this same issue with a Cisco PIX 506E but decided to upgrade the hardware and see if that resolve the issue. It ran for well over a year and our assumtions was that the issue was resolved. I was looking in the direction of the security-association lifetime but if we power cycle the unit, I would expect that it would kill the SA but even after power cycling, the VPN does not come up automatically.
Any assistance would be appreciated.

Inserting a Flash video and the Bandwidth Monitor
I am new to Captivate, and I want to be sure I'm following
some practical guidelines for inserting Flash video in my Captivate
slides.
I know there are quite a few variables relating to practical
bandwidth usage--basically, we are creating elearning presenations
that will have "talking head" videos embedded within. These
presentations will be available for download via our LMS site, both
within the US and overseas.
I have utilized Captivate's Bandwidth Monitor to gauge the
bandwidth hit each video slide is responsible for. However, I don't
believe the numbers I'm getting back: because I've set each
embedded video to "Pause slide till end of video", all the slides
are reporting the same length in seconds, KB per sec and Video KB
numbers.
Can someone suggest a practical method for setting up the
videos such that the Bandwidth Monitor can interpret them
correctly? Can you also suggest a rule of thumb for maximum length
for each slide with an embedded video (320 X 240) in it?
Thanks in advance,

"Discoverying Proxy" across a IPSEC Tunnel over wireless
Bear with me here, there are lot of moving parts in this puzzle, and I'm unsure where to look.
Users are using IE7 (some IE8's), group policy has "Automatically Detect Settings", and we have published a WPAD DNS entry, and are hosting the PAC file on the S370 box. We're very early in our deployment, so we're still functioning in "Monitor mode", till management has some information, and will direct us on what traffic they will allow .
The majority of users are located at our main site, the same site our Proxy is at, these users are having zero problems. For all intents and purposes, they don't even know the proxy is there.
about 30% of our users are located at remote sites. They are connected via an IPSEC L2L VPN tunnel (ASA5505 at remote site, connecting to an ASA5550 at main site)
The users using a wired connection work fine
Wireless users, connecting via LWAPP accesspoints (Wireless LAN controller version 4.2.176.0) at the remote sites, experience a delay connecting to the proxy, usually a few minutes. I actually believe that they are bypassing the proxy, since it takes two minutes. Unfortually, most of my users at the remote sites are wireless.
Thing's I'm immediately going to try are upgrading to the latest version of WLAN controller software, and then open a TAC case on the wireless LAN controller, but before I do this, has anyone run across something similar to this before? (Proxy discovery having issues across an IPSEC tunnel)
MikeHi Javier,
Please explain to me how I should explain this technically elaborate issue to either ISP tech support? :-P
Well, I tried my best and ended up on the phone for 5 hours with 6 different techs between Verizon and TWC BC. I should get paid for explaining them the basics of networking.
Anyhow, my last desperate attempt was to ask the tech to reboot my ONT so I'd get a new IP. Maybe some traffic balancer or filter didn't like my source and destination IP combination. Maybe it was cursed.
Ring. Ring. I finally got an awesome tech (John) from Verizon who actually knew what he was talking about. I connected my Verizon supplied router again and asked if he could log into it or run pings from it remotely (to show him that I'm not crazy). Though other techs told me that was not possible, he did in just a few seconds without much pain. He saw the pings failing as well. Then he said pings from the Verizon ONT gateway were successful, so I assumed it must have been an issue somewhere in Verizon's neck of the (network) woods where the problem persisted.
Long story short: The new IP address worked like a charm and no more packet drops. -
I have cisco 1841 Software (C1841-ADVIPSERVICESK9-M), Version 12.4(25f) router IPSEC tunnel intermittently get dropped.
Following are error message

could you please help in isolating issue.Hi,
You can see this information:
Routers without Call Admission Control for IKE
If the IKE process is under heavy load, incoming IKE packets may spend too much time in the IKE input queue which will result in the generation of a error level (severity 3) Syslog message. The Syslog message is %CRYPTO-3-IKE_PAK_IN_Q_TIME_LIMIT_EXCEED which has this format:
%CRYPTO-3-IKE_PAK_IN_Q_TIME_LIMIT_EXCEED : Pak spent too much time in the IKE input queues
Additional information on those syslog messages can be found at http://www.cisco.com/en/US/docs/ios/12_3t/system/messages/smg2tmsd.html#wp715560.
All %CRYPTO-3-IKE_PAK_IN_Q_TIME_LIMIT_EXCEED messages should be investigated to determine if this issue is being exploited.
Do you have a ISM module to encrypt the traffic, or you are using the built-in crypto engine to encrypt the traffic? (show inventory) would show the hw modules.

VLAN's over Internet/IPSec Tunnel
Hi All !
I have a problem.
I have trunked 5 VLANS from various sites over sattelite and have them all ending on a hub router ,
but my difficulty now is in getting them sent to the HQ over the internet.
I have thought about only 2 ways of possibly being able to do this
1. Get a leased Line :-)
2. and the only feasable alternative ! is to get the VLANs sent per IPSec over the internet but this is my problem....
How do I get a packet from a VLAN into an IPSec tunnel and vice versa ?
What equipment would I need ? (more switches/routers)
Do I need 1 IPSec tunnel for each VLAN to keep them separate from each other ?
Can someone please help.You have posted this same question on the WAN Routing and Switching forum where it has gotten some responses. I suggest that we consolidate the discussion of this question on that forum.

we have connected our two branches using Ipsec tunnel?connection speed is 2Mbps.and we are accessing a server from the 2Mbps enabled plant.After upgrading to 5Mbps also very slow.other end of the tunnel is 5Mbps.
is there any default speed for tunnel?site to site tunnel?Disclaimer

Generally, there's no logical bandwidth cap on an IPSec tunnel. The tunnel might have a low default bandwidth setting, but that doesn't actually limit tunnel performance.
That said, there's much that can impact an IPSec tunnel's performance.
First, encryption can be very processor usage intensive, so performance will depend much on the supporting hardware.
Second, encryption consumes additional bandwidth, for its overhead, which can be a fairly large percentage for small packets.
Third, an IPSec tunnel can often lead to packet fragmentation, which consumes both additional bandwidth and CPU performance.
There are many performance measurement tools, some free, that you might use. Personally, on Windows hosts, I often use PCATTCP. It's a very simple tool; I find the UDP bandwidth generator often good for testing end-to-end bandwidth capacity. For example, I might set it to send 10 Mbps to the far side to confirm 5 Mbps gets there. -
IPSec tunnel on sub-interface on ASA 5510
Hello All,
I working on a security solution using ASA firewall and need some technical advice on ASA. Is it possible to setup a IPSec tunnels on each subinterface of a physical interface on ASA 5510?
I would be greatul if someone please reply post this with some details.
Regards,
MudsHi Jennifer,
Thanks very much for your reply. I understand where you coming from, but the reason of using sub-interfaces is that, we have only one physical interface on the firewall connected to the MPLS cloud, and we need to setup a seperate IPSec tunnels for each client for security and integrity. In the current scenario, I have static peers and we can easily setup a static route to peer address.
Many thanks for your assistance, please feel free to to advise if you have any other suggestion.
Regards,
Muds -
Cisco ASA 5505 Site to site VPN IPSEC tunnel to an Clavister Firewall
Hi,
I have weird problem with a Site to site VPN tunnel from a Cisco ASA 5505 to an Clavister Firewall.
When I restart the Cisco ASA 5505 the tunnel is up and down,up, down, down, and I get all strange messages when I see if the tunnel is up or down with the syntax: show crypto isakmp sa
After a while like 5-10 min the vpn site to site tunnel is up and here is the strange thing happening I have all accesslists and tunnel accesslists right I can only access one remote network (Main site Clavister Firewall) trought the vpn tunnel behind the Cisco ASA 5505, and I have 5 more remote networks that I want to access but only one remote network is working trought the vpn tunnel behind the Cisco ASA. I see that when I do this syntax in ASA: show crypto ipsec sa.
They had a Clavister Firewall before on that site before and now they have a Cisco ASA 5505 and all the rules on the main site thats have the big Clavister Firewall is intact so the problems are in the Cisco ASA 5505.
Here is some logs that ASDM give me about the tunnel issue, but like I said, the tunnel is up and only one remote network is reachable in that tunnel.....

All these remote networks are at the Main Site Clavister Firewall.
Best Regards
MichaelHi,
I'd start by getting the configuration of the remote site related to Local/Remote network configurations and go through them. Even though no changes have been made.
If they are mirror images of eachother already I'd say its probably some problem related to Cisco/Clavister setup
Seems especially wierd to me that one of the error messages includes 0.0.0.0 lines.
I have run into some problems with L2L VPN configurations when our Cisco device just doesnt want to work with the remote end device. In some cases we have confirmed that our networks defined for the L2L VPN are exactly the same and yet when checking debugs on the ASA side we can see the remote end device using totally wrong network masks for the VPN negotiaton and therefore it failed. That problem we corrected with changing the network masks a bit.
Maybe you could try to change the Encryption Domain configurations a bit and test it then.
You could also maybe take some debugs on the Phase2 and see if you get anymore hints as to what could be the problem when only one network is working for the L2L VPN.

Multiple site to site IPSec tunnels to one ASA5510
Question on ASA VPN tunnels. I have one ASA 5510 in our corporate office, I have two subnets in our corporate office that are configured in the ASA in a Object group. I have a site to site IPSEC tunnel already up and that has been working. I am trying to set up another site to site IPSEC tunnel to a different location that will need to be setup to access the same two subnets. I'm not sure if this can be setup or not, I think I had a problem with setting up two tunnels that were trying to connect to the same subnet but that was between the same two ASA's. Anyways the new tunnel to a new site is not coming up and I want to make sure it is not the subnet issue. The current working tunnel is between two ASA 5510's, the new tunnel we are trying to build is between the ASA and a Sonicwall firewall. Any help would be appreciated.
Hi,
Regarding setting up the new L2L VPN connection..
Should be no problem (to my understanding) to configure the new L2L VPN connection through the other ISP interface (0/3). You will need to atleast route the remote VPN peers IP address towards that link. The L2L VPN forming should add a route for the remote networks through that L2L VPN. If not reverse route injection should handle it in the cryptomap configurations.
I guess rest of the setup depends on what will be using the 0/0 ISP and what will be using the 0/3 ISP.
If you are going to put the default route towards the 0/3 ISP you will have to think of something for the 0/0 ISP if some of your local LAN devices are going to use it for Internet also. (Possible routing problems) On the other hand if you have remote VPN Client users using the 0/0 ISP there should be no routing problem for them as they would be initiating connection through that 0/0 ISP link through ASA so ASA should know where to forward the return traffic.
Most of my 2 ISP setups have been implemented with a router in front of the actual ASA/PIX/FWSM firewalls where the router has performed Policy Routing based on the source IP address from the firewalls and then settings the correct gateway towards the correct ISP.

All the traffic go through IPsec tunnel(site to site ) ,but something seems not working correctly
Hi, all,
I have seen a good post in google.com about how to make all the client's traffic though IPsec tunnel then out to the Internet from the Main site,now I attach this configuration and application for discussion, and what the problem is that I am still confused with the configuration on Main site , I hope anyone who can tell me more detail and how to accomplish it. Any answer will be appreciated , thank you !

Question ? :
Mine is a very simple configuration. I have 2 sites linked via an IPsec tunnel. Dallas is my Main HQ R1 and Austin R2 is my remote office. I want all traffic from Austin to route thru the tunnel up to Dallas, then out to the Internet.
Dallas (Main) Lan Net is: 10.10.200.0/24
Austin (Remote) LAN Net is: 10.20.2.0/24
The Dallas (Main) site has a VPN config of:
Local Net: 0.0.0.0/0
Remote Net: 10.20.2.0/24
The Austin (Remote) site has a VPN config of:
10.20.2.0/24
Remote Net: 0.0.0.0/0
The tunnel gets established just fine. From the Austin LAN clients, I can ping the router at the main site (10.10.200.1). This is how I know the tunnel is created, but I cannot ping anything beyond the router from the Austin LAN, e.g. 8.8.8.8.
I'm sure it's something simple I failed to configure. Anyone have any pointers or hints?
Answer:
Thanks to Jimp from the other thread, I was able to see why it was not working. To fix, I had to change the Outbound NAT on the main side to Manual. Then I created a new Outbound NAT rule that included the subnet from the Austin network (10.20.2.0). Basically, I just created a copy of the default rule and changed the Source network.
Once I made this change, Voila! Traffic from the remote side started heading out to the Internet. Now all traffic flows thru the Main site. It makes perfect sense why I needed to make this change, it just took a slap in the head from Jimp to point me in the right direction.
My question ?
