• PIX IPSec tunnel - IOS, routing Options

  Hello

  I have an IPSec Tunnel between a PIX firewall and a router Cisco 1721.

  Have I not all options about any routing protocol can I use?

  Are there plans to add GRE support to PIX, so that EIGRP, OSPF can be used?

  ------Naman

  Here's a URL that tells how to configure GRE over IPSEC with OSPF. http://www.Cisco.com/warp/public/707/gre_ipsec_ospf.html

• IOS router VPN Client (easy VPN) IPsec with Anyconnect

  Hello

  I would like to set up my router IOS IPsec VPN Client and connect with any connect.
  Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

  It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

  I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

  Please let me know how if this is possible.

  Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

  http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

  But I am in any way interested in using IPSec and SSL VPN on a router IOS...

  It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

  The configuration guide (here) offers detailed advice and includes examples of configuration.

• Create safer self-signed certificates on IOS router?

  I use a router in 1921 and use partially as an AnyConnect (WebVPN) server for remote access in the location.  The certificate I used was a self-signed certificate & trustpoint generated on the router.  I am running as the last IOS available track to ensure that it has all the latest features.

  Do a quick check of SSL against her of Qualys, he seems to have a lot of weaknesses and known vulnerabilities.

  * Poodle TLS

  * TLS 1.0 only

  * SHA1

  * Diffie-Hellman 1024 bits

  * Some algorithms of older encryption which seem to be available (but I've never specified), as TLS RC4_128_MD5

  The encryption mechanism and controls to create the cert don't give me much choice in the matter.

  Is there a new or better way to create a more secure certificate chain on an IOS router?  I couldn't find the instructions anywhere.

  Robert

  Take a look at my guide to private networks virtual Suite-B.  It creates more secure certificates.  Note my comment about the minimum software version to use.

• Cisco IOS router 837 - configure DDNS / dynamic DNS

  I have an Internet, connected to my Cisco router link. The package that I subscribed comes with a dynamic IP address. I said me, if I need remote access in the Cisco router, I need to enable the DDNS function. Is this possible on a Cisco router? I have been informed that this feature is not supported. Please help me

  Hi Bro

  Yes, Cisco ASA and Cisco IOS router supported DDNS. Just make sure you have the right version of IOS, which you could refer to this URL of Cisco http://www.cisco.com/en/US/docs/ios/12_3/12_3y/12_3ya8/gt_ddns.html#wp1202953.

  Please refer to the config below made with dyndns.org.

  !

  IP domain name dyndns.org
  8.8.8.8 IP name-server
  !

• 15.1 TMS does not respect the preferred routing protocol

  TMS 15.1

  C series: TC7.2.1, TC7.3.4

  SX20 and 80: TC7.3.4 and EC8.01

  All the saved settings to VCS with addresses both H.323 and SIP.

  Conference TMS-settings of parameters / advanced: shares of routing protocol: H.323

  By default the Protocol of appeal located on all the evaluation criteria: H.323

  When creating new conferences, connection parameter is defined as "SIP" despite the preference above, this to H.323 does not change the connection string to [email protected] / * / the alias preferred without any suffix.

  I do not see anything either in the TMS open and resolved the issues list, then, until I opened a case with TAC, has anyone already opened a file, or found a way to solve this problem? (Couldn't see this issue in TMS 14.4.x)

  Thank you/Bravo

  /Jens

  Hi Jens,

  I can't reproduce your problem here.  I have two end points recorded on my VCSes, and when their scheduling in TMS 15.1.0 it is showing that H.323 in connection settings.

  If I click on "Settings" under the Action on the far right of the display of connection settings in MSD, I can change it to "IP - SIP" and used addresses change to SIP, and if I change it back to "IP - H.323", it changes again in the H.323 addresses.

• IPSEC and routing protocols

  Hello world

  I read that IPSEC does not support routing with VPN's Site to the other protocols because both are Layer4.

  This means that if Site A must reach the B Site over a WAN link, we use static IP on the Site A and Site B router?

  In my lab at home I config Site to Site VPN systems and they work correctly using OSPF does that mean that IPSEC supports the routing protocol?

  IF someone can explain this please?

  Thank you

  Mahesh

  There is no problem with the routing on IPsec protocol, there are limits to some implmentations.

  Our old (strives, but still popular) crypto maps where such implemtation.

  What you need to remember, is that to make routing protocols (more) on IPsec, you must ensure that multicast is allowed through, i.e. your traffic selectors should be postponed. Another thing is that some of these protocols do a check if Hellos were recived leave a subnet connected etc etc. Of course, this isn't a problem with BGP (or most of the problems can be overcome easily).

  New implementations - side Cisco using protections of tunnel - we can run protcols routing on IPsec with very few restrictions.

• IOS router with several groups of VPN

  Similar to a discussion, I read with a PIX firewall, I need to set up multiple VPN groups on IOS-based router to support different levels of security. For example, a VPN "GUESTS" group would only have access to 1 server, while the VPN "ADMIN" group would have access to the entire network.

  With a PIX firewall, you can simply specify additional group names (for example "group1 vpngroup',"vpngroup group2"and so on). However, I have not been able to find how do with IOS-based router (Cisco 831 12.3 (4) T) running.

  For example, I have these dynamic groups of VPN:

  the crypto isakmp client configuration group of GUESTS

  password1 keys

  DNS 10.1.1.1

  swimming POOL1-IP pool

  Configuration group customer crypto isakmp ADMIN

  key password2

  DNS 10.1.1.1

  POOL2-IP pool

  ! - Users get authenticated to a RADIUS server

  list of card crypto CRYPTOMAP customer VPN-USER authentication

  ! - The problem is that line taken out. "I can only specify an allow list (a group name) for this encryption card!)

  card crypto CRYPTOMAP ADMIN isakmp authorization list

  I did research on this site, Google, usenet and ORC and have not found what I'm looking for. Any ideas?

  Thank you.

  Command 'isakmp authorization list' you do it reference does not refer to the VPN group, it refers to a whitelist of AAA name which States that the groups are configured locally. Change to the following:

  AAA authorization groupauthor LAN

  card crypto isakmp authorization list groupauthor CRYPTOMAP

  The "groupauthor" is just a label that matches the encryption to the aaa command. Your clients VPN will be accompanied to a specific group depends on what group name, they set up in their VPN client.

  See http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080095106.shtml for details, it's a HW 3002 client to a router but the router config is exactly the same thing.

• How pix handles more specific routes

  I have a question about the way in which a course of pix handles as shown below:

  Route inside 10.0.0.0 255.0.0.0 10.0.0.1

  Route dmz1 10.21.21.0 255.255.255.0 10.21.21.1

  is the pix able to distinguish the most specific of the road like a router, or is it getting confused. I could not find any documentation on it. Please let know us if someone managed to find all the details on this

  Thank you

  Sam

  Yes, the PIX will use the specfic road more to make routing decisions... just like IOS only.

• IPSEC VPN between Pix 515E and 1841 router

  Hi all

  BACKGROUND

  We have implemented a site to site VPN IPSEC between a Pix 515E 8.0 operation (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and the ASDM the pix to build initial tunnels. Now the site with the router is evolving into a dynamic IP address from the ISP so we have implemented dynamic DNS to update dynamic IP address.

  PROBLEM

  The problem is that ASDM will not allow us to set a domain as the address of peers, it will not accept an IP address. We believe that the solution will be to remove the static Crypto map and replace it with a dynamic Crypto map on the side of Pix. Our questions are simply; is this the best solution? can change us the original static list or is it better to delete and make a new dynamic encryption card? Y at - it a shortcut to change the config command-line? This is a real network, so just check it out before make us any changes on the live kit.

  Any help much appreciated.

  You don't have to change anything when the peer-address changes. The dynamic crypto map aims to take dynamic peer connections. The only thing to remember, is that only the dynamic peer can initiate the connection. And you reduce your security if you use Pre-Shared key that now you can use a generic-PSK character.

  As I remember, the PIX / ASA does not support the dynamic use of FQDNs for peer-resolution. This feature is supported in IOS.

  For a feature, it would be preferable to static IP addresses on both sides.

  If you see the MM_WAIT_MSG2, which means that her counterpart (the other side) does not answer and this side where you can see the status MM_WAIT_MSG2 sent the first message IKE, however, did not hear of the peer.

  You can check if UDP/500 is stuck on the way between the 2 sites.

  Try running traffic on the other side and see if you also get the same status of MM_WAIT_MSG2. If you do, that confirms 100% 500/UDP is blocked on the way between the 2 sites.

• Cannot create the routing protocol ospf

  Hello experts,

  I had a problem to activate OSPF routing IPv6 using Cisco 3845R with IOS ver: (C3845-ENTSERVICES-M), Version 12.4 (24) T. I am able to configure IPv6 on the interfaces and etc but not able to use OSPFv3.

  No idea why? Is this due to the IOS itself?

  Kindly illuminate.

  Kind regards

  Alex

  The version you use supports IPv6 support but not OSPFv3. You can check by looking in the browser functionality.

• RA on IOS router VPN

  Hello Experts,

  Can someone send me the link on how to set up remote access VPN on Cisco IOS routers (authentication of remote users based on user names configured locally on the router itself)?    I found a few links, but they are all authencating by certificate, LDAP users.     I need authentication direct simple remote control-users by using the name of normal user/pass created on the router IOS locally.

  I don't have CA or LDAP server to authenticate remote users.  I just need simple authentication as what Cisco ASA.
