I've searched through the archives here and didn't quite see this addressed.
Several of us here at work have Macs, including iPhones. I've been tasked with attempting to get our iPhone 3GS' working with VPN to our Cisco ASA 5540, ASA version 8.0(4).
It continues to tell me my secret/password is incorrect. As I look through the config on the iPhone, there are very few parameters to tune. My first suspicion was the IKE proposals weren't compatible. For example, we don't have 3des/md5, but we do have 3des/sha.
I began logging in tonight while watching the syslog via ASDM. The only logs I see say:
Denied ICMP type=3 from xx.xx.xx.xx on interface Outside
Group = Our_Group, IP = xx.xx.xx.xx, Error: Unable to remove PeerTblEntry
Group = Our_Group, IP = xx.xx.xx.xx, Removing peer from peer table failed, no match!
I Googled around, but still can't make much sense of this. I also noted there is an extensive babble of this issue on discussions.apple.com - many different viewpoints and experiences.
Does anyone here know how to get this working correctly, or what the problems are?
