https://github.com/apache/cloudstack/pull/872
I have not been able to make the `Remote Access VPN` work with Mac. I have
tried both `L2TP over IPSec` and `Cisco IPSec` (bare ipsec I believe), neither
work.
I am getting the same problems that Rohit had above. I have tested in 3
different network environments. From the office, from home and over 3G by
creating a wireless hotspot and I get the same results in all situations.
I have run the following command on the VR to enable more detailed logging
`ipsec stroke loglevel cfg 2`.
Here is a dump of the logs when attempting to connect. It looks like the
connection is established, but there seems to be an issue doing the final
negotiation. I have been trying different configurations to see if I can find
one that works, but I have not been able to find a config that works yet. I
have also flushed my iptables to be sure it is not an issue with the firewall.
Here are the logs:
