IPsec connection is established between a Sophos Firewall device and a third-party firewall. Tunnel established but traffic stops later
During the phase 2 negotiation, the local and remote subnets specified on the firewalls didn't match. See the following image:Įnter the following command: ip xfrm policy You can see that the SA (Security Association) isn't shown. Sign in to the CLI and click 5 for Device management and then click 3 for Advanced shell.Įnter the following command: ipsec statusall.Phase 1 is up\ Remote peer reports INVALID_ID_INFORMATION If they match, check the remote firewall logs for the cause.Make sure the phase 2 settings for encryption and authentication algorithms and DH group match on both firewalls.The remote firewall shows the following error message: NO_PROPOSAL_CHOSEN Phase 1 is up\ Initiating establishment of Phase 2 SA\ Remote peer reports no match on the acceptable proposals

Update the local and remote ID types and IDs with matching values on both firewalls.Įrror on decryption of the exchange\ Information field of the IKE request is malformed or not readableĬause: The cause is likely to be a preshared key mismatch between the two firewalls.Check the logs on the remote firewall to make sure the mismatch of ID types has resulted in the error.Example: You've configured the local firewall's IPsec connection with Local ID set to IP address, but the remote firewall is configured to expect a DNS name. Remote peer reports we failed to authenticateĬause: The remote firewall couldn't authenticate the local request because the ID types don't match. We have successfully exchanged Encryption and Authentication algorithms, we are now negotiating the Phase 1 SA encryption (hashing) key The strongSwan log shows the following messages: If all the settings match, the remote firewall administrator must check the configuration at their end since the remote firewall has refused the connection.Gateway address: The peer gateway address you've entered on the local firewall matches the listening interface in the remote configuration.Phase 1: Encryption, authentication, and DH group.Make sure the VPN configuration on both firewalls has the same settings for the following:.The strongSwan log shows the following error message: Remote peer is refusing our Phase 1 proposalsĬause: Mismatched phase 1 proposals between the two peers.
