This makes sure IP address is active. After a vRouter is recreated (e.g. reboot via CloudStack UI) and Remote Access VPN enabled, VPN won't work anymore. Here is the abbreviated output of "ipsec auto -status" while we were having the issue: root@r-10-VM:~# ipsec auto --status 000 using kernel interface: netkey 000 interface lo/lo 127.0.0.1 000 interface lo/lo 127.0.0.1 000 interface eth0/eth0 169.254.1.45 000 interface eth0/eth0 169.254.1.45 000 %myid = (none) After this commit, the following occurs and VPNs work: root@r-10-VM:~# ipsec auto --status 000 using kernel interface: netkey 000 interface lo/lo 127.0.0.1 000 interface lo/lo 127.0.0.1 000 interface eth0/eth0 169.254.1.45 000 interface eth0/eth0 169.254.1.45 000 interface eth1/eth1 xxx.xxx.xxx.172 000 interface eth1/eth1 xxx.xxx.xxx.172 000 interface eth2/eth2 192.168.1.1 000 interface eth2/eth2 192.168.1.1 000 %myid = (none) eth1 interface IP is masked, but now ipsec sees all the interfaces and VPN works. Looks like this bug was introduced by Pull Request #1423 It added code to start ipsec (cloudstack/systemvm/patches/debian/config/opt/cloud/bin/configure.py) if vpnconfig['create']: logging.debug("Enabling remote access vpn on "+ public_ip) CsHelper.start_if_stopped("ipsec")
