- Two new strongswan.conf options allow to fine-tune performance on IKEv2 gateways by dropping IKE_SA_INIT requests on high load. - IKEv2 charon daemon supports start PASS and DROP shunt policies

strongSwan plugins. The strongSwan distribution ships with an ever growing list of plugins. This allows us to add extended and specialized features, but keep the core as small as possible. Many components of strongSwan come with a set of plugins. The plugins for libstrongswan provide cryptographic backends, URI fetchers and database layers.

I have 2 sites with an IPSec tunnel in between. The tunnel is up and working fine. However, I'm having some strange performance issues.

Jan 11, 2019 · 1st, once my ipsec connection is up, my performance, as measured through iperf3, drops from 9.4Gb/sec to ~800Mb/sec. 2nd, the NFS mount can't do anything once the tunnel is up and all related interfaces are using mtu 9000.

These optimizations achieve significant throughput gains. Our work demonstrates that comparable performance between plain IP and IPsec connections is possible ...

And change strongswan.conf to change radius server to 127.0.0.1, then the radius request reject in no time and for my previous patch this call still return and the user still can login.

IKEv2 Cipher Suites¶. IKEv2 Cipher Suites. The keywords listed below can be used with the ike and esp directives in ipsec.conf or the proposals settings in swanctl.conf to define cipher suites. IANA provides a complete list of algorithm identifiers registered for IKEv2.
