I have noticed when connecting to my office via my MacBook Pro that I'm able to access both the office network and my home network, in other words split-tunneling is turned on. We have explicityly disallowed this on the hardware side.

This occurs using either the Cisco VPN client that is built-in, or one I installed after the fact. Has anyone else experienced this?

I'm wondering if this is a known issue or if there's something I'm not configuring correctly.

Thanks!

I have the same 'problem' here. – radius Oct 17 '09 at 14:59
Are you by any chance accessing local resources using ipv6? – Helvick Oct 17 '09 at 17:12
I like your thinking Helvick. I certainly could be, but I'm more of a Windows expert so I'm not sure where to look for that on a Mac. I'll try digging around to find out, but do you know how I could find that information? – Ken Pespisa Oct 18 '09 at 0:00
I've found that i can still access servers on my local lan while connected to a Cisco VPN by using their bonjour name. Such as; server.local I have the Cisco client setup under Snow Leopard and I am not experiencing the same 'problem' as you when trying to access local server by their FQDN. – Jordan Eunson Oct 18 '09 at 22:00

There's a separate setting for "Allow local LAN access", which is what you're describing -- this isn't quite the same thing as split tunneling. Split tunneling will use your non-tunneled default gateway to reach things that aren't explicitly in a list of tunneled networks. A better test would be if you go to, say, http://whatismyipaddress.com/ and it shows your home network's IP, then you're really split-tunnel.

Thanks, good explanation. I did see my corporate IP address when I went to that site, and that makes sense. – Ken Pespisa Oct 25 '09 at 13:01
