EFW OpenVPN + iOS + OpenVPN client

[Guest]

I've been fighting for the last few days and I wanted to get a weigh in if this actually possible.

I am trying to get a tunnel to my GREEN network from an iPhone using the OpenVPN client.

So far I get a connection and IP from the GREEN subnet but I ping anything on the GREEN zone.

Can anyone tell me definitively if it is possible to do this using either SSL or IPSEC and what server configuration I should be making to accomplish this?

I've found various bits of info  but nothing so far that puts it all together specifically for EFW.

I'm getting the following error in the log after connection:

It seems I have to force OpenVPN to use tun mode to support iOS clients.

As far as I can tell you do that with a 'dev tun' statement in the openvpn.conf.  However, if I add that line to the openvpn.conf.tmpl the service won't start.

Am I missing something here?
