By disabling charon.prefer_configured_proposals in strongswan.conf this may be changed to selecting the first acceptable proposal sent by the peer instead. In order to restrict a responder to only accept specific cipher suites, the strict flag (!, exclamation mark) can be used, e.g: aes256-sha512-modp4096!
Configuration Files¶ General Options¶ strongswan.conf file; strongswan.d directory; Used by swanctl and the preferred vici plugin ¶ swanctl.conf file; swanctl directory; Used by starter and the deprecated stroke plugin ¶ ipsec.conf file; ipsec.secrets file; ipsec.d directory; IKE and ESP Cipher Suites¶ IKEv1 Cipher Suites; IKEv2 Cipher Suites While the ipsec.conf(5) configuration file is well suited to define IPsec related configuration parameters, it is not useful for other strongSwan The file is hard to parse and only ipsec starteris capable of doing so. The format of the strongswan.conf file consists of hierarchical sections and a list of key/value pairs in each section. Each section has a name, followed by C-Style curly brackets defining the section body. strongSwan is an OpenSource IPsec-based VPN solution. This document is just a short introduction of the strongSwan swanctl command which uses the modern vici Versatile IKE Configuration Interface. The deprecated ipsec command using the legacy stroke configuration interface is described here. For swanctl.conf style configurations, it is not an issue, so remote_addrs or local_addrs can be set to 127.0.0.1 to prevent strongSwan from considering the conn in the conn lookup when a peer tries to connect. In this example, only remote_addrs is set to 127.0.0.1. You are free to choose local_addrs, remote_addrs or both.

Jul 08, 2020 · strongSwan has a default configuration file located at /etc/ipsec.conf. It is recommended to rename the default configuration file and create a new file. To rename the default configuration file, run the following command: Once you have the strongSwan VPN server setup, you can now proceed to test the IP assignment and local connection via the VPN server. In this demo, we are using Ubuntu 18.04 and CentOS 8 as our test strongSwan VPN clients. The strongswan.conf option. charon { cache_crls = yes } activates the local caching of CRLs that were dynamically fetched from an HTTP or LDAP server. Cached copies are stored in /etc/swanctl/x509crl using a unique filename formed from the issuer's subjectKeyIdentifier and the suffix .crl.
Configure strongSwan When using IPsec-VPN to create a site-to-site connection, you must configure the local gateway according to the IPsec connection configured for the Alibaba Cloud VPN gateway. This article takes strongswan as an example to show you how to load a VPN configuration in a local site.

The focus of the project is on strong authentication mechanisms using X.509 public key certificates and optional secure storage of private keys and certificates on smartcards through a standardized PKCS#11 interface and on TPM 2.0.
