Understanding AH vs ESP and ISKAKMP vs IPSec in VPN tunnels
 
18:30
This is a sniplet from the Cisco SIMOS course, where we discuss the logical constructs behind a site-to-site IPSec VPN. I hope that this content helps you understand what's happening behind the scenes of your VPN's.

Pre-setup: Usually this is the perimeter router so allow the firewall. Optional access-list acl permit udp source wildcard destination wildcard eq isakmp access-list acl permit esp source wildcard destination wildcard access-list acl permit ahp source wildcard destination wildcard You need to enable to securityk9 technology-package Router(config)#license boot module c2900 technology-package securityk9 Router(config)#reload Task 1: Configure the ISAKMP policy for IKE Phase 1 There are seven default isakmp policies. The most secure is the default. We will configure our own. You can remember this by HAGLE. Hash, Authentication, Group (DH), Lifetime, Encryption. Router(config)#crypto isakmp policy 1 Router(config-isakmp)#hash sha Router(config-isakmp)#authentication pre-share Router(config-isakmp)#group 5 Router(config-isakmp)#lifetime 3600 Router(config-isakmp)#encryption aes 256 We used a pre-shared key for authentication so we need to specify the password for the first phase. Router(config)#crypto isakmp key derpyisbestpony address 208.77.5.1 show crypto isakmp policy Task 2: Configure the IPsec Policy for IKE Phase 2 Configure the encryption and hashing algorithms that you will use for the data sent thought the IPsec tunnel. Hence the transform. Router(config)#crypto ipsec transform-set transform_name esp-aes esp-sha-hmac Task 3: Configure ACL to define interesting traffic Even though the tunnel is setup it doesn’t exist yet. Interesting traffic must be detected before IKE Phase 1 negotiations can begin. Allow the local lan to the remote lan. Router(config)#access-list 101 permit ip 192.168.0.0 0.0.0.255 10.0.0.0 0.0.0.255 show crypto isakmp sa Task 4: Configure a Crypto Map for the IPsec Policy Now that interesting traffic is defined and an IPsec transform set is configured, you need to bind them together with a crypto map. Rotuer(config)# crypto map map_name seq_num ipsec-isakmp What traffic will be interesting? The access-list we made before. Router(config-crypto-map)#match address 101 The transform-set we created earlier for the IPsec tunnel. Router(config-crypto-map)# set transform-set transform_name The peer router you’re connecting to. Router(config-crypto-map)#set peer 172.30.2.2 You need to set the type of DH you want to use. Router(config-crypto-map)#set pfs group5 How long these setting will last before it’s renegotiated Router(config-crypto-map)#set security-association lifetime seconds 900 Task 5: Apply the IPsec Policy Apply the crypto map to the interface.

The demo is based on software version 12.4(15)T6 and uses IPSec, ISAKMP, tunnel-groups, Diffie-Hellman groups, and an access-list. The demo is based on the popular book "The Accidental Administrator: Cisco Router Step-by-Step Configuration Guide (http://amzn.com/0983660727) and includes a link where you can download a free copy of the configs and the network diagram.

Show crypto isakmp sa The following four modes are found in IKE main mode MM_NO_STATE* – ISAKMP SA process has started but has not continued to form (typically due to a connectivity issue with the peer) MM_SA_SETUP* – Both peers agree on ISAKMP SA parameters and will move along the process MM_KEY_EXCH* – Both peers exchange their DH keys and are generating their secret keys. (This state could also mean there is a mis-matched authentication type or PSK, if it does not proceed to the next step) MM_KEY_AUTH* – ISAKMP SA’s have been authenticated in main mode and will proceed to QM_IDLE immediately. The following three modes are found in IKE aggressive mode AG_NO_STATE** – ISAKMP SA process has started but has not continued to form (typically do to a connectivity issue with the peer) AG_INIT_EXCH** – Peers have exchanged their first set of packets in aggressive mode, but have not authenticated yet. AG_AUTH** – ISAKMP SA’s have been authenticated in aggressive mode and will proceed to QM_IDLE immediately. The following mode is found in IKE Quick Mode, phase 2 QM_IDLE*** – The ISAKMP SA is idle and authenticated Here are a few more commands we can issue to get a quick glimpse of the status of any IPSec VPN’s. sh crypto ipsec sa – Now this output can really daunting at first just due to the amount of information that is displayed here but there are a few key things to watch out for. Such as the #pkts encaps/encrypt/decap/decrypt, these numbers tell us how many packets have actually traversed the IPSec tunnel and also verifies we are receiving traffic back from the remote end of the VPN tunnel. This will also tell us the local and remote SPI, transform-set, DH group, & the tunnel mode for IPSec SA. sh crypto session Up-Active – IPSec SA is up/active and transferring data. Up-IDLE – IPSsc SA is up, but there is not data going over the tunnel Up-No-IKE – This occurs when one end of the VPN tunnel terminates the IPSec VPN and the remote end attempts to keep using the original SPI, this can be avoided by issuing crypto isakmp invalid-spi-recovery Down-Negotiating – The tunnel is down but still negotiating parameters to complete the tunnel. Down – The VPN tunnel is down. So using the commands mentioned above you can easily verify whether or not an IPSec tunnel is active, down, or still negotiating. Next up we will look at debugging and troubleshooting IPSec VPNs * – Found in IKE phase I main mode ** – Found in IKE phase I aggressive mode *** – Found in IKE phase II quick mode DE NADA SIRVE MONTAR UNA SONDA SINO SE APLICA EL CORRECTIVO, QUEDARIA CON UP-NO-IKE Otro punto es que es multipoint pero al final son IP´s fijas en ambos extremos remoto y central.

Want to learn more? Watch our other Cookbook videos here: https://www.youtube.com/playlist?list=PLLbbcH8MnXJ5UV22hUQRIv0AHSqp81Ifg In this video, you will learn how to troubleshoot a site-to-site IPsec VPN that provides transparent communication between a Headquarters FortiGate and Branch office FortiGate. This video will show you how to diagnose common problems when your tunnel connection fails, and how to adjust your settings when the tunnel drops on and off. This video includes common Preshared Secret Key issues, Security Association or “SA” proposal errors, quick mode selector issues, and more. By the end of this tutorial you should have a better understanding of how to use these debug commands for basic troubleshooting.This video is recorded on FortiOS 5.2.6, and although the GUI options may vary, the troubleshooting tips and CLI commands are relevant for most recent builds.
