I'm currently using the Cisco VPN client, version 4.6.03, to try to connect to a Cisco concentrator. The application launches fine and connects fine, but once fully connected, no traffic is sent or received. It seems to lock up my network interface. What's more, it will not disconnect. In order to use the interface again, I must kill the VPN client. If I want to launch the VPN client again, I must restart the machine. Bringing the interface down and up (ifconfig en0 down; ifconfig en0 up) does not help. The prior version did not do this, but I do not have access to that version, as this new version was part of the OS 10.4.7 update (I'm now on 10.4.8.)

Other interesting information: I also use Virtual PC. The Cisco VPN client gives me the same problems, though it will cleanly disconnect. I've tried that exact same client with the same configuration on a true PC and it works fine, leading me to believe it is either the VPN Client on my Mac, or the interface card itself is going bad in some odd way that it can not work with a VPN.

I could really use some assistance, as neither Apple nor Cisco have any useful information on their websites regarding this issue.

    I am sure I have seen a thread or two on Cisco VPN which broke with 10.4.8. You could also google or search MacIntouch and MacFixit on this issues which has been reported on with some news from readers.

    Did you leave or clone your system before upgrading so you can fall back and continue using 10.4.7? Never update before backing up.

    Thank you for the reply. Unfortunately, even after having spent considerable time reading all related threads on the topic, nothing addressed this very odd issue. I have, fortunately, found a fix.

    What did work:
    I was able to locate a version of Cisco VPN Client 4.6.04 (the previous version was 4.6.03) and it is now working on Mac OS X 10.4.8.

    What did not work:
    Following Apple Tech support's advice, I did an Archive Install, rolling back to 10.4. I did each point reference update (10.4.1, then 10.4.2, and so on.) After each install I tested the existing client. It would start but would immediately crash for failure to find a particular library file. I did this all the way through 10.4.6, and up to 10.4.8 with no luck.

    Remaining issue:
    The Virtual PC version of the VPN client (4.0.5(d)) still seems to not work. The next step will be to re-install the PC version of the VPN client. Perhaps that will work.

    Just FYI, your version of the Cisco client seems to be rather old. The current version is 4.9.00.0050. I don't know if there's some reason you need to stay with the 4.6.x series, but if not, you might want to update to the current client version.

    Regards.

    Dave,

    thank you. Unfortunately, the latest version to which I have access is 4.6.04. My organization does not make 4.9 available and Cisco does not offer the software freely from the Cisco site. However, if you happen to know of a public location where the newer software can be had, I would be happy to get it. It appears Cisco does not distribute this directly and that it can only be distributed by organizations with licenses for a Cisco VPN package.

    Thank you,

    Jonathan

    You can download it (as least as of right now) from MacUpdate.

    Whether there's some reason why your client would need to match the version of software running the Cisco VPN server, I don't know. So you'll want to keep the 4.6.x client just in case the 4.9 client doesn't work for some reason.

    You might want to prod your organization to make the more current client available. The older clients wont' work with Intel-based Macs, should your organization have or acquire any.

    Cheers.

    I have exactly the same symptoms and have just tried with both the 4.7 and the 4.9.0.1 version of the Cisco VPN client.

    I can't get it to work. It connects but refuses to disconnect and I can't access the servers.

    Where can I find the 4.6.03 version?

    Thx,

    Bo

    Ok, found the 4.6.03 version but unfortunately it didn't solve the problem...

    Has the latest version fixed the horrible kernel panic issues on the mac pro? That put me off the cisco mac release altogether.

    BTW, stumbled across this the other day:

    Claims Cisco compatibility, may be worth a look. They have a 30-day trial available...
