Solved: Re: Cisco ASA - RAVPN IPSEC not working

LovejitSingh1313 · ‎08-27-2020

Hello Guys, @balaji.bandi @Marvin Rhoads @Rob Ingram @Scott Fella @Vikas Saxena @nkarthikeyan

I configured the RAVPN ikev1 IPsec using an old client on the firewall but it's not working. I tried the same configuration and it works fine.

I get the following error message.
Secure VPN Connection terminated by Peer.
Reason 433. (Reason not specified by peer)

It happens when it accepts user password and start negotiating security policies.

It looks like some policy is interfering with it but I do not know which commands I should run to find out the conflicting policy/ACLs.

Thanks,

Aug 27 15:57:09 [IKEv1]Group = Test12345, Username = lsingh, IP = 99.250.11.11, Cannot obtain an IP address for remote peer

this error jumps out at me, do you have an IP address pool configured correctly?

here is the common problem and solution :

VPN Client Drops Connection Frequently on First Attempt or "Security VPN Connection terminated by peer. Reason 433." or "Secure VPN Connection terminated by Peer Reason 433:(Reason Not Specified by Peer)"

Problem

Cisco VPN client users might receive this error when they attempt the connection with the head end VPN device.

"VPN client drops connection frequently on first attempt" or "Security VPN Connection terminated by peer. Reason 433." or "Secure VPN Connection terminated by Peer Reason 433:(Reason Not Specified by Peer)" or "Attempted to assign network or broadcast IP address, removing (x.x.x.x) from pool"

Solution 1

The problem might be with the IP pool assignment either through ASA/PIX, Radius server, DHCP server or through Radius server acting as DHCP server. Use the debug crypto command in order to verify that the netmask and IP addresses are correct. Also, verify that the pool does not include the network address and the broadcast address. Radius servers must be able to assign the proper IP addresses to the clients.

Solution 2

This issue also occurs due to the failure of extended authentication. You must check the AAA server to troubleshoot this error. Checking the server authentication password on Server and client and reloading the AAA server might resolve this issue.

Solution 3

Another workaround for this issue is to disable the threat detection feature. At times when there are multiple re-transmissions for different incomplete Security Associations (SAs), the ASA with the threat-detection feature enabled thinks that a scanning attack is occuring and the VPN ports are marked as the main offender. Try to disable the threat-detection feature as this can cause a lot of overhead on the processing of ASA. Use these commands in order to disable the threat detection:

no threat-detection basic-threat
no threat-detection scanning-threat shun
no threat-detection statistics
no threat-detection rate

For more information about this feature, refer to Threat Detection.

Note: This can be used as a workaround to verify if this fixes the actual problem. Make sure that disabling the threat detection on the Cisco ASA actually compromises several security features such as mitigating the Scanning Attempts, DoS with Invalid SPI, packets that fail Application Inspection and Incomplete Sessions.

Solution 4

This issue also occurs when a transform set is not properly configured. A proper configuration of the transform set resolves the issue.

Hello @balaji.bandi

I already followed this article and tried all the options, I did not see the debugs when my VPN client try to connect it. I need help with commands where I can find the ACL or policy which is not allowing the VPN session ?

Thanks

Solution 1 - was your issue if you closely look the config -

Hi,

I am not clear on your comment - "I configured the RAVPN ikev1 IPsec using an old client on the firewall but it's not working. I tried the same configuration and it works fine."

Is it working randomly or did you try the configuration on another device (ASA or computer) and then it worked?

Are you using the old VPN client? some ciphers are depreciated so may no longer be supported.

Provide your configuration and ASA version.

LovejitSingh1313 · ‎08-27-2020

Hello Rob,

I installed and old Legacy client 5.0.7.04 on windows 10 PC with help of some registry editing and then I added the Group-policy creds and IP in the client but it is failing while negotiating security policies, I tried the same config on another firewall with same OS version and it worked with that firewall.
I want to find out why the firewall is failing it.

I attached the config. Thanks

Thanks,

Rob Ingram · ‎08-27-2020

From which ASA is that configuration from, the working or non working ASA?

From the working ASA, login as a user and then run "show vpn-sessiondb detail anyconnect" and provide the output for review. Also provide the configuration of the other ASA.

The old VPN client does not support the latest ciphers, is there a configuration difference between the 2 ASAs in regard to ikev1 or ssl configuration? The working ASA might be configured to use certain ciphers compared to the other ASA.

Any reason why you cannot use AnyConnect?

Are you using IKEv1 or SSL when connecting?

LovejitSingh1313 · ‎08-27-2020

The configuration I attached is for not working ASA. I setup on outside2 interface.

We are using Ikev1 RAVPN over Ipsec, not having license for AnyConnect?

The other firewall where its working, I configured in a same way through the ASDM and I did not encounter any menu where i can choose/see ciphers.

Rob Ingram · ‎08-27-2020

Ok. Provide the configuration of the other ASA so we can compare ike/ipsec policies and provide the output of "show vpn-sessiondb detail" of a logged in user so we can determine what ciphers have been negotiated.

LovejitSingh1313 · ‎08-27-2020

From the Working Firewall and I am connected with RAVPN client.
