• RV325 Cisco VPN throughput?

  Dear Sir.

  I intend to buy this VPN router to connect my laptop to the home network via the VPN Ipsec configuartion Office of Mr. I have a few questions to ask.

  First of all, my laptop can see all computers on the network with 100 M/s?

  Second, I used this connection for my software Vray for rendering distributed remotely. This is the main objective. Now, I m using the Asus RT - 66U router built in open VPN service and speed 2 M/s, but the actual data flow for this process is 20 M/s. I wonder if I buy cisco RV325 which can help to solve this problem?

  Thank you

  David

  Hello David,.

  You can find in the RV320/325 Datasheed IPSec VPN throughput is 100 Mbps:

  http://www.Cisco.com/c/en/us/products/collateral/routers/rv325-dual-Giga...

  Please note that the upload speed and download you'll actually are also determined by your ISP, as well as the way which you VPN tunnels will have many assets on the router.

• Cannot ping vpn client of 1721 cli on the tunnel endpoint

  I have a 1721 fortunately supporting ipsec vpn client connections. With one small exception, everything works perfectly fine.

  The VPN pool is 10.10.10.1 - 10.10.10.254

  The interface internal f0 is attributed to 192.168.1.254/24.

  In my example:

  Ip address of the VPN client is 10.10.10.5

  The host address of an arbitrary machine on the internal lan is 192.168.1.151

  I am able to ping 192.168.1.151 10.10.10.5

  I'm * not * able to ping 10.10.10.5 192.168.1.254 using the cli on the 1721.

  There is a very good reason to want to solve this problem. I would like to be able to access a tftp server on the client vpn directly from the router in order to download the new startup-config files. Is it possible to get the traffic of vpn-/ tunnel-point endpoint client tftp to travel through the tunnel?

  When you ping from the CLI on the router, the packet will be from the external interface, not the IP address fa0 interface. The VPN client and the router only built a tunnel from the 10.10.10.5 address the 192.168.1.0 network, then the router not cryptera a package that her origin is outside the IP address.

  Try to ping extended to 10.10.10.5 and source of 192.168.1.254 package and see if it works. If it does, you will have also to the source of your TFTP packets from inside interface, you can do with:

  IP tftp source interface fa0

• VPN Throughput

  I have just set up a point-to-point VPN tunnel between a 3825 central and two 2811 remote on a 100 MB connection via Ethernet.

  I'm using the AES 256 encryption for isakmp and ipsec. Speeds w/o the active tunnel between the remote and central site are that 60-70 Mb speeds WITH the tunnel are 28-32 MB.

  Why such a significant decrease in speed? This is a good result and I would be able to increase the speed of some how?

  CPU utilization on the 2811 about 75% increases when a large amount of traffic is passed. I guess it has something to do with the speed decreases.

  The process of encryption/decryption of packets is performed by the processor. Just like on a busiest PC CPU, they slow everything performs. You're in luck, however. Cisco has a PURPOSE which performs the encryption/decryption and allows the CPU to perform other tasks. You will see a 'speed' when using the card for the PURPOSE of gain. Here is a link for more information.

• The ISR G2 GET VPN throughput

  I looked up a document detailing the flow of VPN to GET on the ISR G2 routers. I only found a general IPSec flow for them, and I couldn't find a document GET VPN for old ISR routers.

  Can someone help me find this information?

  Kind regards

  Xavier

  Xavier,

  It is always better to ping your Cisco system engineer for this information.

  I don't think we have an external update (module ISM came out considering in particular).

  As employees of Cisco, we cannot provide internal data and the majority of the results of the tests are labeled "confidential Cisco.

  Provide you those could make trouble for us :-)

• RV016 for 20 site to site VPN

  Best regards

  Currently I have a RV016 and a router RV110W to try to connect to one of our branches (retail of clothing) with the central site, we managed to install and VPN works very well, but we have more than 19 stores throughout the country.

  In stores, we can have 2 to 8 computers such as point of sale, one of them acting as server to our system, this server is required to connect to the main server in the central office.

  My question is: we have received some tips from people who say that these facilities are too small to connect to our 20 stores, anyone know if this is true? These RV series are suitable for this amount of connection of branches?

  Thanks in advance for any help!

  Hello

  The ASA5506 is a very good security device and give you a lot more security.   The RV016 isn't a security feature, but it has a firewall.  Less flexible, less features.

  You need the ASA5506-x w / power of fire and more security license.  With the license of security Plus the 5506 do support that 10 IPsec VPN tunnels.  With the license, it supports 50.

  The broadband VPN (speed), however, is substantially the same between the ASA and the RV016.  ASA get 100 Mbps VPN and the RV016 get 97 Mbit/s throughput.  very similar.

  The neck of the bottle is actually with the RV110w on the remote site.  There only get 5 Mbps VPN throughput.  You should consider the RV130W with 50 Mbps VPN throughput.

  Kind regards

• Forward traffic IPSec VPN

  Hi dude, I want to address this topic to understand ipsec VPN throughput.
  I have 1 router 1921 and 1 ASA 5510 behind the router. I want to set up remote access on ASA firewall by traffic shaping router forwards (port UDP 500 and UDP 4500 port). I have 1 public IP address and I already configure NAT on the router. In fact, I heard that IPsec cannot pass through the NAT. So if I want to configure VPN on SAA, it is possible to do? All the guys comment on and propose your idea to me. Thanks for your reply.

  Hello

  When you say, you have a public IP address. Is this address IP is assigned to the interface of the router or not attributed distinct IP address.

  If its not assigned public IP address, you can make static NAT with ASA outside the IP address to a public IP address on your router as below

  {100.100.x.x}fa0/0<-(R1)->fa0/1{192.168.100.1}<------->{192.168.100.2}eth0/0(ASA)eth0/1{172.16.01}

  IP nat inside source 192.168.100.2 static 100.100.x.x

  This way you have full IP to IP NAT.

  If you got the only IP address that is assigned to the interface of the router then you will need to nat as port said

  For VPN gateways running versions of the Cisco IOS software prior to version 12.2 (13) T, the functionality of IPSec passthrough is required on the router that runs PAT to enable payload ESP (Encapsulating Security) through.

  Note: This feature is called IPSec through NAT (NAT) network support Advisory software (registered only customers).

  In order to initiate the tunnel of the local counterpart (PATed), no configuration is necessary. In order to initiate the tunnel of the remote peer, these commands are needed:

  • IP nat inside source static esp inside_ip interface, interface

  • IP nat inside source udp static inside_ip 500 interface interface 500

  For VPN gateways that run a version of the Cisco IOS software later than 12.2 (13) T, IPSec traffic is encapsulated in data protocol packets UDP (User) port 4500. This feature is called IPSec NAT transparency . In order to initiate the tunnel of the local counterpart (PATed), no configuration is necessary.

  In order to initiate the tunnel of the remote peer, these commands are needed:

  http://www.Cisco.com/c/en/us/support/docs/security-VPN/IPSec-negotiation-IKE-protocols/23820-iOS-Pat-IPSec-tunnel.html

  • IP nat inside source udp static inside_ip 4500 4500 interface interface

  • IP nat inside source udp static inside_ip 500 interface interface 500

• VPN-3DES encryption speeds

  Anyone know if there is any Cisco documentation which corresponds to what the 3des encryption maximum speeds are by router.

  I am looking specifically for the Cisco2621 router without the GOAL card.

  Thank you

  Hi Patrick,

  Peroformance without OBJECTIVE cards numbers are difficult to obtain that the processor runs other operations at the same time and would not be a difficult number just for the VPN/throughput performance. With the GOAL card numbers can be seen at: http://www.cisco.com/en/US/products/hw/routers/ps259/products_data_sheet09186a0080088750.html

  In addition, you must contact your local Cisco SE or team account for any number of performance, they should be able to provide those.

  Thank you

• Use of the PIX of the to encrypt a WAN link

  We are looking to purchase a service of dark fiber between 2 data centers.

  We want to encrypt all traffic flowing between the sites, but many dedicated devices stop to 45 MB.

  We use PIX at each end, just to drive the connection like a virtual private network, but what speed I would get the link?

  Thank you!

  Hello

  The PIX and ASA can deliver more than 400 Mbps 3DES/AES VPN throughput. (Models of high-end with gigabit interfaces).

• ASA5540 flow

  Hello

  ASA5540 firewall throughput is 650Mbps, 3DES/AES VPN throughput is 325Mbps.

  Is the total throughput of 650 M + 325 M firewall? Or 650M?

  Thank you

  650 is the total cumulative flow amount that will support the device.

  The notation 325Mbps is simply to specify that the device can process 325Mbps of 3DES/AES encrypted data. These data would be the limit of 650Mbps.

• Cisco 1921 / K9

  Hi all

  1: my Corp Office, I installed a K9 Cisco 1921, I want to know that how IPSec VPN Tunnel Cisco 1921 /k9 can support and what is the IPSec VPN throughput?

  2: I have connected a link bandwidth (150 Mbit/s Download and 25 Mbit/s upload) to my Cisco 1921/K9, I want to know if Cisco 1921/K9 is able to manage bandwidth 150Mbps?

  3: If one of my retail site runs on 10 Mbps of bandwidth on Cisco RV220W connect to Cisco 1921/K9 for the Corp. Office. How much bandwidth IPSec tunnel will use?

  4: I have 200 points of sale and each have 5 computers, wifi and son (Mix few are on wifi and little are wired) that is block to install to the location of the retail of Cisco RV325 Cisco RV220W or 3.

  Thank you

  Sandy

  For retail locations, I would watch the series 880 s. They are available with built-in ADSL/VDSL modems and also wireless. The WIFI network can be controlled by a WLC.

  Management is the reason why I use RV-devices. As far as I know, they have still any IOS-like. The AP can be controlled with a WLC which also makes very easy to manage.

  For the router to 4000, I know that what is stated in the data sheet and the part of the config guide of license (the last router Cisco 4000 I used performed a decade... ;-)).

  But there are more feature-licenses like DRY/SSEC you need.

  It seems that the performance is entirely controlled by the license and the 100 / 300 Mbps is the performance of the services. But without the HSEC license, you are limited (as for many cisco routers) to 85 Mbps encrypted 225 tunnels and bandwidth.

• PIX501 Question flow

  Hello

  I have a PIX501, that is about 2 years 6.3 (5) running. I wonder what the flow is about it. I looked through the cisco Web site, but I noticed that the PIX501 is now 100 MB outside the Interface. Was there a change to this. I am convinced that mine has a 10 MB int. I guess that it is half-duplex.

  I am upgrading to the 17 MB internet connection and wonder if the PIX can handle this.

  Otherwise, and since I do not think that Cisco will never bring Pix 7.0 on these units, I look something like a 871, etc.. How to compare the capabilities of FW to PIX.

  Thank you

  I don't think you need to worry unless you use VPN tunnel on it

  When you upgrade the PIX 501 version 6.3, the inside interface is automatically upgraded to 100 Mbps duplex full. During the upgrade process, the system displays the message "interface ethernet1 can be defined to 100full."

  Summary of performance

  ClearText flow: up to 60 MB/s

  Concurrent connections: 7 500

  THE 56-bit IPsec VPN throughput: up to 6 MB/s

• LAN-to-LAN tunnel between VPN 3000 and Cisco 1721

  Hello

  I have a current LAN-to-LAN tunnel configuration between VPN 3000 (3.6) and Cisco 1721 (12.2 (11) T).

  When I use the encryption = authentication and Des-56 = ESP\MD5\HMAC-128 for the IPSec Security Association, everything works fine.

  However, I would like to Turn off encryption for some time getting the speed improvements, so I changed

  Encryption = null esp (in 1721) and to "null" in VPN-3000.

  Now the tunnel is setup but I can spend only ICMP traffic. When I pass the traffic UDP\TCP the message below appears the Cisco 1721

  % C1700_EM-1-ERROR: error in packet-rx: pad size error, id 75, hen offset 0

  Has anyone seen this behavior?

  All those put in place an IPSec Tunnel with only the ESP authentication and NO encryption between VPN-3000 and Cisco 1721?

  Thanx------Naman

  Naman,

  Disable you the vpn Accelerator? "no accel crypto engine. Sure that you can't do with a null module vpn.

• VPN between a router from 1721 to a Juniper srx 240

  Hello

  Is it possible to set up a vpn tunnel on a 1721 router that uses the following ios:

  C1700-y7 - mz.124 - 13b .bin

  I thought I had read somewhere that the tunnels were not supported in the 1700s, but wanted to make sure. If they are I would like to know if they are supported in ios preceding.

  Thank you.

  Yes, 1721 supports the termination of VPN tunnels and you need IP/firewall and IPSec 56 or sets features IOS IP/firewall and IPSec 3DES.

  Here is the Cisco1721 router for your reference data sheet:

  http://www.Cisco.com/en/us/products/HW/routers/ps221/products_data_sheet09186a00800920ec.html

  However, please note that Cisco1721 has reached EOL:

  http://www.Cisco.com/en/us/prod/collateral/routers/ps221/prod_end-of-life_notice0900aecd8044473f.html

  In addition, the current ios you have: c1700-y7 - mz.124 - 13b .bin does not support IPSec. You need to download IOS with IP/firewall and IPSec 56 OR / IP/firewall and IPSec 3DES IOS feature sets to support IPSec.

  I hope this helps.

• VPN on 1721

  I'm still learning and I hope it's a good place to ask questions. I take the ICND2 in 4 days and I'm more than ready for this. Right now I play with VPN and just wanted to know if that would work. I have the following network...

  ISP > 2621XM FA0/0 FA0/1 > 3524XL FA0/1

  3524XL various ports > guest LAN

  3524XL FA0/3 > FA0 1721

  I have a static IP from the ISP assigned to 2621XM / FA0/0 and overloaded NAT for the hosts on the LAN to access the internet

  I have an another static NAT with static IP to the ip address of the 1721 / interface FA0

  The following configuration for VPN work will have access to my network? It's like 'Router on a stick' for VLANs, but it's for the VPN.
