ikev2 - ASA & IOS - part two

In this post I would like to analyze most common mistakes and check how we can troubleshoot them. Please check my previous post to learn more about scenario and the configuration.

1. problem #1

The configuration has been changed and now I try to establish the secure connection. 
 
R18#ping 9.9.9.9
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 9.9.9.9, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
R18#

on the ASA and the router I enabled debug command:

as we can see in the above messages, there are not the same ipsec policies on these devices.
 
R17#sh run | i crypto ipsec transform-set
crypto ipsec transform-set TS esp-aes esp-sha256-hmac
R17#

and on the ASA we have:
 
asa2# sh run crypto
crypto ipsec ikev2 ipsec-proposal IPSEC-PROPOSAL
 protocol esp encryption aes-256
 protocol esp integrity sha-1

Let’s fix it on the router:
 
R17(config)#crypto ipsec transform-set TS esp-sha-hmac esp-aes 256

and test it once again:
 
R18#ping 9.9.9.9
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 9.9.9.9, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 68/86/112 ms
R18#

2.problem #2

In the second case there is another problem which I tried to identify from debug outputs.

R18#ping 9.9.9.9
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 9.9.9.9, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
R18#

As you see above the ping is unsuccessful. Let’s look on these outputs.

I ommited the output from the phase 1 as there wasn't any useful information. I start here from ipsec (phase 2):

As you see above there is a problem with an access list: “proxy identities not supported”. Let’s check access lists on both peers:
 
asa2# sh run | i access-list
access-list VPN extended permit ip host 7.7.7.1 host 9.9.9.9

R17#sh run | i access
access-list 101 permit ip host 9.9.9.9 host 7.7.7.7
R17#

As you see there is a problem with the access list on R17. It should be:

access-list 101 permit ip host 9.9.9.9 host 7.7.7.7

Let’s fix it and test it once again:
 
R18#ping 9.9.9.9
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 9.9.9.9, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 68/75/84 ms
R18#

As you see to investigate the problem you need to check debug outputs from two peers becuase in most cases one side can’t help you in your troubleshooting.

What should you know about HA 'override enabled' setting on Fortigate?

High availability is mandatory in most of today's network designs. Only very small companies or branches can run their business without redundancy. When you have Fortigate firewall in your network you have many options to increase network availability. You can use Fortigate Clustering Protocol ( FGCP ) or Virtual Router Redundancy Protocol ( VRRP ). FGCP has two modes: 'override' disabled (default) and 'override' enabled . I'm not going to explain how to set up HA as you can find many resources on Fortinet websites: https://cookbook.fortinet.com/high-availability-two-fortigates-56/ https://cookbook.fortinet.com/high-availability-with-fgcp-56/ Let's recap what is the main difference between them. The default HA setting is 'override' disabled and this is an order of selection an active unit: 1) number of monitored interfaces - when both units have the same number of working (up) interfaces check next parameter 2) HA uptime - an

MAC Authentication Bypass

One of the method to control your network is using MAB feature. It is helpful in case you have devices without dot1x functionality. Today I will try to implement basic configuration and analyze log messages. There is only one switch SW1 and one device attached to port Fa1/0/2.   ! aaa new - model aaa authentication dot1x default group radius ! ! int Fas1 / 0 / 2 authentication host - mode single - host authentication port - control auto mab ! I haven’t configured ACS yet but let’s see what error message I receive:   SW1 ( config - if ) # mab - ev ( Fa1 / 0 / 2 ): Received MAB context create from AuthMgr mab - ev ( Fa1 / 0 / 2 ): Created MAB client context 0x1100000F mab : initial state mab_initialize has enter mab - ev ( Fa1 / 0 / 2 ): Sending create new context event to EAP from MAB for 0x1100000F ( 0000.0000 . 0000 ) mab - sm ( Fa1 / 0 / 2 ): Received event 'MAB_START' on handle 0x1100000F mab : during state mab_initia

Inpection of asymmetric sessions on FortiGate

There is one feature available on FortiGate, and I think you should know it, as it modifies a bit what we know about stateful firewalls. In past every packet was treated individually and you had to create policies in both directions. With stateful firewalls we can track connections, and by checking couple of attributes, we can treat them as part of the same session. For example when you initiate connection from a host1 to host2, the returning connection from host2 to host1 will be treated as part of the same connection (session). They have to have the same source/destination and destination/source IPs, port numbers and interfaces.There is an exception from this rule and FortiGate in some specific cases can accept connections on port which was not used in the initial connection. Let me explain how it works on the below example:      The host1 has a default gateway on R1 (10.0.1.2), but you may notice that it is not the optimal path to host2 subnet. When we analyze the packet flo
