IPS/ACL/ZBF precedence on router IOS

• Site to site VPN with router IOS

  I want to create a VPN site-to site on the Internet. On the remote site, aside from the VPN to the head office, there should be no traffic not allowed in internal from the Internet to the network and that there should be no traffic from the internal network to the Internet allowed. The internal network will run a private 192.168.x.x address range.

  I'm going to use a Cisco 2811 router integrated of services on the remote site and this will last an IPSec VPN that will end a hub at Headquarters. I understand that this router has an IOS and IPS firewall built in.

  Would I be right in thinking that because I don't want to have access to the Internet (except VPN) or should I configure IOS firewall features on the router? And there is no point in the configuration of the features IPS wouldn't?

  My thought is that only an entry in list of unique access to deny pi a whole applied inbound to the interface that connects to the Internet would be the best strategy. I think that the command "sysopt connection permit-ipsec" should allow the VPN to form even with the ip address to deny any any ACL (or is it just a Pix command? If Yes, then I have to allow ESP and UDP 500 (ISAKMP) from the public address of the hub at Headquarters to allow the VPN to form wouldn't I?).

  Think I'll probably expand slightly the access list to allow the icmp Protocol, ssh and https traffic from the IP address of firewall seat outside so that I can monitor the remote site and access it safely if the fail VPN.

  And I wouldn't need one access list on the interface connected to the internal network I would like because the range of addresses would be not routable, so they would not be able to initiate connections to the Internet (all the trffic to the remote site is specified under a valuable traffic to bring up the VPN)

  Use one of the IOS Firewall inspect commands or the IPS would be useless and have no effect in this case wouldn't it?

  I really just need to know if the ip address to deny any any ACL on the external interface on the remote site is the best solution (and the simplest), and whether it will be safe.

  We used to use fiewalls Pix for remote VPN site to site, Amazon refuse incoming connections on the external interface by default but now I have been informed that these series 2800 routers will be used later, so I would get my thoughts straight and be able to build safe to do the same work all existing PIX are doing (they are all installed for just the VPN at Headquarters as in) the first paragraph).

  I would like any advice or thoughts on the subject. I don't know there must be a ton of people who put routers for the same purpose.

  Thank you in advance.

  I did a lot of implementations site VPN to another using IOS routers. They work very well. Based on my experience I offer these comments and I hope that they will help you:

  -you don't want a list of incoming access on the external interface, but you want more in it than simply refuse an ip. There is no permit-ipsec sysopt connection in IOS so you want to certainly allowed ISAKMP and IPSec/ESP. I suggest that you also want to allow SSH. I would like to allow ICMP but only starting from the address space of the network head end. I do not allow HTTPS since I generally do not allow the http server on the router. If you want HTTPS then certainly enable it. To facilitate the ping and traceroute on the remote I frequently allow icmp echo-reply, timeout and unreachable port from any source.

  -I want to put an inside interface access list. There are certain types of traffic that I don't want to send from the Remote LAN. I have usually refuse any trap SNMP or snmp for LAN devices and refuse out of the local network icmp redirects. I also often configure RPF controls inside interface to catch any device which is misconfigured.

  -If you want to allow SSH when the VPN is not active (and I highly recommend that you do) then you will probably need to configure at least 1 (and maybe more) users and password of the router ID. And you want to configure authentication on the vty use local authentication if the head end authentication server is not available.

  -I'm not clear from your description if you plan to run a dynamic routing via the VPN Protocol. I wish I had a dynamic routing protocol because I want to announce a default route to the remote control via the VPN. I do not locally configure a default route on the remote router. This way if the VPN tunnel is up there is a default route pointing to the tunnel and if the VPN tunnel is not up then there is no local route by default and users on the remote database can not access the Internet. It is a simple and very effective method to ensure that all user traffic must pass through the central site.

  -regarding the routes defined on the remote router, my approach is that I define a static route for the endpoint of the tunnel to allow the tunnel to implement and I set up static routes for the subnet to the head of line I can SSH. And I do not configure other static routes the on the remote router.

  -You probably want to disable cdp on the external interface and also to disable the proxy-arp (and I don't make any ip unreachable).

  -There is frequently a problem when using VPN site-to-site with fragmentation. If a device on the local network sends a frame of maximum size, and then the router needs to add additional headers for IPSec, then the frame is too large and requires fragmentation. I like to use tcp adjust-mss ip to control the chunk size for TCP traffic and avoid any problems with fragmentation.

  -I don't think you want to set up the firewall or IPS from the features of IOS on the 2811.

  I hope that your application is fine and that my suggestions could be useful.

  [edit] after posting my response, I read through your post again and realize that you make to a VPN concentrator. The approach I have proposed on the execution of a routing protocol works for me because I usually have a router IOS in mind. It would not work to connect to a hub.

• Automatic demotion of the Anyconnect Client (router IOS)

  Hello

  We run a Cisco Anyconnect client with a router IOS environment (2921) as the lead aircraft.

  We have upgraded the client package on the router to the latest version 3.1.13015. After installing this package on the customers, we discovered a bug. Windows-based computers are not able to establish a VPN connection more (authentication and auto-package-level still works, but then an error message is displayed ("unable to cannot" or similar).)

  I returned the package on the router back to an older version (3.1.11004), but is not beeing auto-installe when a client with the new version (buggy) connects.

  Is it possible to configure the router to force a downgrade to the customers, or is the only way to workaround to manually uninstall the package on clients?

  Thank you

  Heinz

  No you can't auto-downgrade the station clients.

  Unfortunately, you will need to uninstall it from the client end, then get the right package (older) of the router.

• Termination of VPN on Pix behind router IOS with private subnet

  OK, basically, I wonder if it is possible to terminate a VPN connection on a Pix 506 Firewall which is behind a router IOS. The public interface of the Pix 506 have a private on a 29 ip address will IOS within the interface. Network is configured as follows:

  Internet as 10Base T

  | (5 public - X.X.X.34. 38)

  | (In WIC-1ENET)

  | (.34 assigned to interface)

  Cisco 1760

  | (Pomp) | (WIC-4PORTSWITCH)

  | | (10.0.0.1 29 on 1760)

  Net private Pix 506

  (192.168.1.0) (10.0.0.2 29 on Pix)

  Now, two internal interfaces of the 1760 are configured to PAT on the IP of the interface of the 1760 and all internet traffic goes perfectly. None of the access lists are currently applied anywhere on the 1760 and a static translation on the 1760 is configured pour.35 to 10.0.0.2 ('public' ip pix). RDP and other services authorized in the pix access list work perfectly well from the outside world when you enter a.35, but if I try to terminate a VPN from a pix 501 for the pix 506 offsite using the Intellectuelle.35 property, it does not work.

  Is it possible to do this type of work setting.

  I realize I could put an external switch to 1760 and run the public subnet directly and individually in the 1760 and Pix 506, however, I really would prefer not no need to do so if it is possible to avoid it.

  Remove the crypto map to the interface on the PIX and reapply.

• tunnel from site to site between router IOS and ASA

  I've combed through the configs on both sides of this tunnel 4 x now and the look of policies as they match. I applied the http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094498.shtml note

  My crypto lsits access are good and my nat on the side of IOS are provided with a map of the route and look good. On the SAA traffic side on the side of the remote tunnel ASA is exempt from NAT. Each side already has a site to another tunnel configuration, so I added the appropriate lines to the existing cryptographic cards which include peers, transform set and match address 'access-list. The polcies crypto isakmp on both ends are compatible. I have attached some configs and debugs (from router IOS), but essentially the newspaper on the SAA starts with the phase 1 is complete and then routing not received notification message, no proposal chosen readings and then it goes to IKE lost the connection to a remote peer, connection, drop table correlator counterpart has failed, no match, the deletion and finally disconnected session reason lost service.

  Their other tunnel stay standing as well as the configuration of remote access vpn connection is good.

• Traffic generated by router IOS inspect IPv6

  I try to configure the IPv6 packets on a router 2911 deep inspection (IOS 15.1 (2) T5) but I'm not able to inspect the traffic generated by router. It is not an option "ipv6 inspect name xxxx udp router-traffic' as in IPv4. So I am unable to ping to the router to a remote host.

  I could solve the problem of ping by simply adding a "permit any any icmp echo response" on my ACL, but I still can't access TCP or UDP based services (DNS, HTTP,...).

  Anyone knows if it is possible to activate the traffic generated by IPv6 router, or is there another solution for this problem? If so, how can I do that?

  Partial configuration:

  ipv6 unicast-routing
  
  ipv6 inspect name SPI_DIALER1_OUT tcpipv6 inspect name SPI_DIALER1_OUT udpipv6 inspect name SPI_DIALER1_OUT icmpipv6 inspect name SPI_DIALER1_OUT ftp

  Former Cisco's IOS 'inspect' system has indeed been deprecated.  You should use zone based firewall now.

  Here is the guide for the care of the IPv6 zone based firewall.

• Traffic to the VPN router IOS NAT tunnel

  I need to configure a VPN tunnel that NATs traffic above him.  I have already established VPN tunnels and NAT traffic.  I did this on a concentrator VPN and ASA, but have seen some places where people say is not possible on a router or I saw real hard evidence that it is.  For example, I use a Cisco 2801 router with 12.4(8a) and advanced security.  This can be quite difficult as the subnet / vlan that we need NAT needs to pass normal traffic on other VPN tunnels and using a NAT on the Internet directly.  Y does it have, any restrictions on it as the IOS version, being a router itself, NAT configuration.  Any help is greatly appreciated.

  Hi James,

  NAT VPN traffic, you can like you do with ASAs on IOS routers.

  If you do, it is that you create an ACL to set traffic to be coordinated, apply the ACL to a NAT rule and a condition that NAT statement with a roadmap to occur only when the traffic will be sent through the tunnel.

• Firewall router ios commands

  In order to solve problems that result from a problem with a vpn connection, where the router contains an ios firewall, knowing the correct controls are essential. What are the proper commands that should be used for the display of information related to vpn problems? For example, on a pix commands show conn, isa to show her, see the ipsec sa, sh help etc exlate in the determination of the issues. What are some commands which correspond to these and others can be used on a router with a firewall ios?

• VPN Client TCP connection to router IOS

  Hello

  I try to get a VPN client to connect via TCP to a router. I currently have the router put in place (and work) in using a VPN - UDP. Unfortunately one of the sites I visit will not allow VPN traffic outside of their firewall. I have searched all over the site of Cisco and can't find any information on the IOS configuration to accept TCP - VPN connections. I would like to change the TCP port 80, so my VPN traffic looks like just standard internet browsing my client firewall. Any links/pointer would be greatly appreciated.

• How is the ACL name of the router for fleeing?

  I want to test running and have a question, the name of the ACL.

  I configured the device blocking on the IDM,

  -blocking interface Fastethernet0/0 =

  -direction = in

  -Pre IDS_PRE = ACL name

  -Ask the IDS_POST = ACL name

  Change a signature "ICMP-echo" to shunhost and update on the router but added new ACL under Fastethernet0/0 as the name IDS_Fastethernet0/0_in_0 and rocking it with IDS_Fastethernet0/0_in_1.

  Q. why the ACL name not follow my name on the IDM?

  Thanks in advance.

  I think that there is some confusion about what are PreACl and PostACL.

  The PreACL and PostACl entries in IDM do not affect what's name created sensor ACL on the router.

  The sensor will always create an ACL that is named with the following format:

  IDS___<0or1>

  So for you the configuration it would create the following names of ACL:

  IDS_Fastethernet0/0_in_0 and IDS_Fastethernet0/0_in_1

  E he uses 2 ACL because it cannot modify an ACL that is currently applied on the interface. So if ACL 0 is currently applied then it will create 1 ACL and then apply ACLs one (which Désimpute ACL 0).

  The sensor can then remove 0 and create a new ACL 0 when a change has to happen.

  So, what are the pre and Post ACL names used for?

  One of the biggest complaints we had with older versions of the probe was that the user could add no lines to the ACL that created the sensor.

  So we came to the top with the pre and Post ACL so that users can add entries to the ACL that creates the sensor.

  The user must connect on the router itself and create an ACL with little matter the name they want. Inside of the ACL, they put the entries they finally want to see at the top of the ACL that will create the sensor.

  When they set up the sensor, they take the name of the ACL, they created and enter it in the field for the name of PreACL.

  The user can do the same for the entries they want at the bottom of the ACL generated by the sensor by creating another ACL on the router. Put it in the Scriptures they want to see at the bottom of the created sensor ACL and then type the name in the name of PostACL field.

  If the names of pre and Post ACL aren't going to use to name the ACL created sensor.

  But on the contrary these ACL is read out of the router by the sensor, and these ACL entries will be placed inside the ACL, created by the sensor.

• Router IOS Cisco Anyconnect ASA configuration

  Hello

  Could someone give me some advice if I can use a Cisco 1812 to connect to a Cisco ASA5512X using Anyconnect. The question we have is that some remote offices may be given fixed IP addresses...

  Thank you.

  AnyConnect cannot be used because there is only one solution-client-software and non-integrated IOS as the EzVPN client.

  You can use dynamic cryptographic cards already offered on the ASA with a card standard encryption on the router, or you configure remote EzVPN on the router and on the SAA EzVPN server:
