• Cisco ISR 4400 series SSLVPN Support

  Hello

  New series routers Cisco ISR 4400 support SSLVPN?

  According to the feature for this, but according to the document browser 4451-X Q & A is not.

  Does that mean I can or Canon use the AnyConnect client?

  Thank you.

  Kind regards

  Armand

  According to documents that I looked, new SRI (4300 and 4400) 4000 series doesn't support SSL VPN at all:

  http://www.Cisco.com/c/dam/en/us/products/collateral/routers/4000-series-integrated-services-routers-ISR/enterprise-routing-portfolio-poster.PDF

  http://www.Cisco.com/c/en/us/products/routers/4000-series-integrated-services-routers-ISR/series-comparison.html

  It is possible that the AnyConnect client may be still usable for IKEv2/IPSec VPN connectivity, but SSL seems to be off the table in these units.

  My guess would be that access the VPN feature is moved exclusively to the portfolio of the SAA, but which is slowed down just think.

• Default configuration of the PFS on the Cisco ISR

  Hello

  I want to learn more about the default configuration of PFS on the Cisco ISR router.

  -Introduction to IP Security (IPSec) encryption - create a Crypto map
  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_tech_note09186a0080094203.shtml#cryptomap

  You can also change the configuration of your PFS here. PFS Group1 is the default value in this example. You can change the PFS to group2, or turn off all together, you should not do.

  DT3-45 a (config) #crypto card armadillo 10 ipsec-isakmp
  DT3 - 45's (config-crypto-map) #set counterpart 192.168.10.38
  DT3 - 45 session key has seconds (config-crypto-map) #set 4000
  DT3 - 45's (config-crypto-map) #set transform-set HAAT PapaBear BabyBear
  DT3 - 45's (config-crypto-map) #match address 101
  --------

  This example has no configuration PFS PFS is set to group1.
  However, the following command reference indicates that PFS is not requested.
  Which is the correct description for the PFS setting?

  -the pfs value
  http://www.Cisco.com/en/us/docs/iOS/Security/command/reference/sec_s2.html#wp1063163

  Default values
  By default, it is not required of PFS. If no group is specified with this command, the Group1 keyword is used by default.
  -------

  Thank you for your cooperation in advance.

  Order is correct.

  If pfs set is not configured in the crypto map configuration, pfs will be negotiated not.

  If set pfs is configured without any group, then it uses default group1

  And if you do not want to use the other group, you set the group # in the command set pfs.

  I hope it is clear now.

• HOW connection NAT on ASA 5505

  Hello guys

  first of all, thank fully any community of cisco, they helped me a lot withouth expert and University...

  Today, I have some question on NAT

  We HAVE site-to-site VPN, his job very well.  our company demand of patern to use the public Ip address instead of the ip address private field of encryption. and they said, you have to NAT for you the private to the PUblic ip address. really, we don't know how NAT for cisco ASA 5505.

  THIS IS THE CASE

  OUR COMPANY = USES CISCO ASA 5505

  OUR PUBLIC IP ADDRESS: 155.155.1555.20

  PRIVATE IP: 192.168.7.2 SOUND LINUX SERVER, THEN HOW WE CAN NAT THIS IP PRIVATE AND CHANGE IN PUBLIC

  Thank you very much

  If you have 1 public IP address and it is assigned to your ASA outside interface, then you need to configure static PAT (you will need to know what exactly they want to access and configure the specific port they need).

  However, if you have a free public IP address, then you need not to know exactly what they need to get to and you can configure the linux server using the public IP to spare.

  Also, they need access to the linux server using public IP via the VPN tunnel (encrypted)? or they are happy to access only via the internet (clear text)?

• How to use controls RS-232 on the edge of Cisco 340?

  Hello friends,

  Can someone please advise on how to run the RS-232 commands in Cisco Edge 340 players?

  I checked the Edge 340 sw configuration guide, but could not find any information related to it.

  Please respond if anyone has an idea?

  Hi Marc,

  Where did you get this 340 edge synchronized with? If its Appspace then you should be able to use appspace to control the TV Tower on and off tension and volume on and off through appspace.

  I have not tried, but you should be able to use any program like minicom to send commands from the Board Office.

• Protect and control the license for ASA with the power of fire

  I had 1 ASA 5515 initially delivered with the software cx, then made room for the software of firepower and got the virtual firesight for 2 devices and license of TAMAS tha L-5515, but this license was told only the URLs and malware license, I thought that this license was for all that since he has no other licenses in the data sheet and it's Reference with more features.

  How can I get the license protect and control now so I can add the asa with the firepower to firesight and apply to all licenses

  Thank you

  Hello

  L ASA5515-TAMAS = SKU license plans to "MALWARE" and "URLFilter" and legally gives the user to updates of the signature "PROTECT + CONTROL". It does not license "PROTECT + CONTROL". You need to buy "ASA5515-CTRL-LIC =" to license "PROTECT + CONTROL".

  Please discuss a case with CISCO GLO, they can help provide a CTRL license

• How in CISCO

  I have the following configuration:

  Private network <->SW <->CISCO VPN <->MODEM to ISP

  I have party VPN configured and working properly. I have a computer in the private network to the static address 192.168.1.100 and an application runs on this subject on the tcp port 8100 for customers.

  Now, I need to connect over the Internet to the application on 192.168.1.100 on port 8100.

  How to configure the CISCO router before inbound tcp port 8100 to machine 192.168.1.100?

  ISP modem will discount all traffic to CISCO device.

  Thank you

  Hello

  Well, I said public_ip just in case you want to use a different IP address to the external interface of the router.

  The extensible keyword allows the user to configure several translations static ambiguous, where an ambiguous translation is translations with the same local or global address.

  Example from a position of the SCC

  IP nat inside source static x.x.x.x y.y.y.y extensible

  IP nat inside source static x.x.x.x z.z.z.z extensible.

  When a packet comes from outside for insde with destination

  It will be sent to x.x.x.x y.y.y.y or z.z.z.z address,

• Issue of NAT for ASA running 8.4 (5)

  We have a client who is about to hang an ASA off the coast of the demilitarized zone of our firewall that is running 8.4 (5). This firewall is currently on another part of our network, and NAT will be considerably changed. Now, everything on the client firewall must be coordinated outside for the same thing as the IP model internal, for example like the old "static (inside, outside) 172.16.16.0 172.16.16.0 netm 255.255.255.0" command.

  When I look at the document from Cisco for (conversion) NAT

  ( http://www.cisco.com/en/US/docs/security/asa/asa83/upgrading/migrating.html#wp96828), I see not all conversions between the two. This is not a "nat 0" because users need access to certain hosts inside the firewall of our customers.

  Can someone tell me please in the right direction? Thank you

  Hello

  Lets assume that the following is true

  • The new ASA has 'inside' and 'outside' network/interface only
  • The ASA News should do EVERYTHING NAT 'inside' to 'outside' to any kind of situation traffic (your firewall handles this?)

  Then you can simply have the ASA with absolutely no. NAT configurations. The ASA with new software releases 8.3 and above all automatically passes all traffic through the ASA UNNATED. We use it on a single client and it works very well.

  Please let me know if the above is the case, or can't think of anything else

• NAT issue ASA 5510

  Just upgraded my ASA 5510 of 8.2 (1) 8.4 (4) 1.  Well, everything seems to work with one big exception.

  NAT statements I had previously remained in force and even seem to reproduce in some cases.

  Now, my question is I've set up a DMZ (security 50) interface and requiring a few servers to connect to the inside interface (Security 100).  I created the necessary NAT statements within the ASDM to allow the DMZ servers to connect to a single inside the server.  However, all the servers in the DMZ can still ping and connect to ALL inside servers.

  An easy way to limit it?  I try to limit the number of servers on the internal network that can access the demilitarized zone, but it seems that the DMZ has free rein at the present time.

  Am happy to post my configs. I opened a case of TAC, but this firewall is still so new, the assistance contract has not yet been addressed by Cisco.

  Thanks in advance.

  I'll look when get home, but it is a quick answer.

  If the RIP is not absolutely necessary for you, try adding the default route to R2:

  IP route 0.0.0.0 0.0.0.0 172.16.2.1

  If you want to use RIP much, add permissions ACL 102:

• Static NAT with asa 5520

  Hi all

  I have the following situation

  The following rules of the static nat

  static (inside, outside) tcp 200.200.200.200 80 10.0.0.200 80 netmask 255.255.255.255

  static (inside, outside) 200.200.200.200 tcp 8080 10.0.0.200 80 netmask 255.255.255.255

  I would redirect all packets destined for port 8080 and 80 IP address 200.200.200.200,

  to the private IP address on port 80 10.0.0.200.

  I tried to do that the ASA said there is already a rule, there is a way it be done?

  Kind regards.

  I don't think you can use port forwarding using the same local destination IP on port 80 in this way, fw will give you duplicate static entries.

  You can however get around and give 10.0.0.200 NIC a secondary IP address i.e. 10.0.0.201 and make electricity as follows.

  static (inside, outside) tcp 200.200.200.200 www 8080 10.0.0.201 netmask 255.255.255.255

  static (inside, outside) tcp 200.200.200.200 80 10.0.0.200 80 netmask 255.255.255.255

  See examples of port forwarding

• Can the NAT of ASA configuration for vpn local pool

  We have a group of tunnel remote ipsec, clients address pool use 172.18.33.0/24 which setup from command "ip local pool. The remote cliens must use full ipsec tunnel.

  Because of IP overlap or route number, we would like to NAT this local basin of 172.18.33.0 to 192.168.3.0 subnet when vpn users access certain servers or subnet via external interface of the ASA.  I have nat mapping address command from an interface to another interface of Armi. The pool local vpn is not behind any physical interface of the ASA. My question is can ASA policy NAT configuration for vpn local pool.  If so, how to set up this NAT.

  Thank you

  Haiying

  Elijah,

  NAT_VPNClients ip 172.18.33.0 access list allow 255.255.255.0 10.1.1.0 255.255.255.0

  public static 192.168.33.0 (external, outside) - NAT_VPNClients access list

  The above configuration will be NAT 172.18.33.0/24 to 192.168.33.0/24 when you go to 10.1.1.0/24 (assuming that 10.1.1.0/24 is your subnet of servers).

  To allow the ASA to redirect rewritten traffic the same interface in which he receive, you must also order:

  permit same-security-traffic intra-interface

• The Global NAT FVRF questions - for Expert

  Hi Expert,

  I have a client with a DMVPN network. Here is a simple drawing of installation:

  

  First I set the router og BRANCH1 config: BRANCH1 - Config.txt

  What the client wants is simple:

  Host 200.200.200.200 reach the host 192.168.100.2 on port 3389.

  So I thought to do the static NAT like this:

  IP nat inside source static tcp 192.168.100.2 3389 100.10.10.2 3389

  but it does not work because the BRANCH1 router is configured with FVRF who wants to say outside interface is in a VRF and local area network inside interface is globally. I couldn't see any traffic coming to the server (192.168.100.2) but I could see the translation in the nat process.

  So I tried to configure the virtual interface of NAT (NVI) I read that NVI works best in the VRF environment. This time with these lines:

  interface FastEthernet0/0
  Description * WAN connection *.
  bandwidth 20000
  IP vrf forwarding DMVPN-VRF
  IP 100.10.10.2 255.255.255.0
  IP access-group OUTSIDEACL in
  activate nat IP
  IP virtual-reassembly
  automatic duplex
  automatic speed
  !
  interface FastEthernet0/1
  Description * to connect to the computer 3 *.
  IP 192.168.100.1 address 255.255.255.0
  NBAR IP protocol discovery
  activate nat IP
  IP virtual-reassembly
  load-interval 30
  automatic duplex
  automatic speed
  No cdp enable

  IP nat source static tcp 192.168.100.2 3389 100.10.10.2 3389 extensible

  Then I finally got some entries of traffic in the server 192.168.100.2. See the Wireshark log:

  200.200.200.200 192.168.100.2 TCP stgxfws > ms-wbt-Server [SYN] Seq = 0 Win = 64240 Len = 0 MSS = 1260

  
  

  192.168.100.2 200.200.200.200 ms-wbt-Server TCP > stgxfws [SYN, ACK] Seq = 0 Ack = 1 win = 64240 Len = 0 MSS = 1460

  So far so good but but... the router sends an ICMP destination 13 unreachable code to the server:

  10.1.0.1 192.168.100.2 ICMP Destination unreachable (Communication administratively filtered)

  I guess that is because the router performs a search in the global routing table instead of the destination FVRF.

  Anyone know how I can fix this problem?

  Maybe a solution to HUB1 for this so everything is managed central, what do you thing?

  Best regards

  Laurent Rlap

  I can't spoke1 config. But first the routing needs to work and I would like to try a leak of the VRF the way in Global.

  IP route 200.200.200.200 255.255.255.255 FastEthernet0/0

  When this is fixed we can watch NAT.

• motor control not to no - heat - how to put in a mode to limit the dissipation of heat from the drive?

  Hello

  I use a system using a SMU with 2 Motors step by step NEMA34-6, driven by the readers of SMD-7621.

  The system needs to be powered 24/24 7/7.

  Most of the time, the engine didn't need to spend...

  It seems that the engine still somehow braking mode 'active', and the player constantly dissipate heat, even if no movement is required.

  I measured the temperature of the steady state of the reader, who is around 50 ° C, measured on the heat sink aluminum.

  It is safe to have the drive constantly at this temperature, 24/24, 7/7?

  Is it possible to move the reader into a kind of mode 'sleep', when no movement is required by the control? Would this mode, if it exists, decrease the temperature of the drive?

  I control the system using Labview on an SMU using a surfboard OR 73xx, so this mode should be controlled via the code of Labivew, in which I could detect situations when I will not have to move the engine more...

  Any help on this will be greatly appreciated.

  J.F.

  Yes, this is the setting you should change.  This player is actually a player movement applied Productss.  I do not know how critical it is to keep your position.  It is possible to lose the position a little bit if you go all the way up to 0%.  For example, if you use microstepping, and you reduce the current to 0, the engine could jump to the next full step.
