Hi,
I would like to use the strongswan load-tester plugin for performance testing
of our vpn systems and was able setup the tunnels with the following
configuration:
# enable the plugin
enable = yes
# 200 connections, ten in parallel
initiators = 10
iterations = 20
# use a delay of 100ms,
delay = 100
# address of the gateway
remote = 192.168.0.1
# IKE-proposal to use
proposal = aes128-sha1-modp1024
# use faster rsa authentication
initiator_auth = pubkey
responder_auth = pubkey
pool = 192.168.40.0/25
# do not request a virtual IP using configuration payloads
request_virtual_ip = no
# disable IKE_SA rekeying
ike_rekey = 0
# disable CHILD_SA rekeying
child_rekey = 0
# do not delete the IKE_SA after it has been established
delete_after_established = no
# shut down the daemon if all IKE_SAs established
shutdown_when_complete = yes
}
I am wondering if there is a way to specify a pool of IPs which are used as
source addresses to initiate the VPNs. My problem is that our DUTs is a blade
based system distributing the tunnels based on src-ip of the initiator and due
to the fact that all tunnels initiated by the load-tester plugin are using the
same ip all VPNs will be established on the same blade.
I found the parameter ”charon.plugins.load-tester.pool” in the documentation
however I am not sure if this parameter is the right one as nothing changed
after I configured it in the strongswan.conf.
Can someone point me into the right direction and tell me if the load-tester
plugin can be configured to use different a different source-ip per
initiator-instance?
Thanks for your help.
Joern
