10.4.8 upgrade breaks Checkpoint Secureclient VPN

tony, i have what may be a similar problem. after i upgraded this laptop to 10.4.8 the VPN (Cisco v4.9) no longer functions properly when connected to secure sites. this happens only on my airport/wireless connection at home (where it counts). basically the VPN will connect but data transfer afterwards is extremely slow. nonsecure sites are fine. seems like a conflict with a specific wireless/network configuration. unfortunately, no-one responded to my post of earlier this week. our local IT guys tried some things but its not yet working. if you have any ideas please let me know.

thanks, tony, but it didn't work. i even did the permissions repair when booted off a cd, and also i cleared-out another ciscovpn folder (under 'frameworks') but i'm experiencing the same problem. looks like i may have to either do a clean system install and go back to 10.4.7, or perhaps wait until .9 comes out, unless you or someone else has other thoughts. but thanks anyway. wayne

Tony (et al?),

Our IT guys figured out the problem or at least a workaround. Try to connect with the VPN and have it fail. Then go to system pref/network/airport/tcp-ip and there's a button for "renew DHCP lease." Click this, and all will be fine. Apparently there are some bad prefs that get wiped when this is renewed.

I don't know if it will recur, but the fix worked the first time at least.

Whew...

Hi Tony,

I can absolutely confirm that 10.4.8 breaks Checkpoint Secureclient VPN. I have the same problem, the airport process loses its mind and goes to ~95% CPU. There are other threads on Airport going to ~100%, like this one:

If you remove Secureclient, the airport process works fine again.
The only workaround I have found, if you want to leave Secureclient installed, is to tell Airport not to remember preferrered networks. You have to go into the Aiport System Preference, click the Options button and uncheck the box to "Automatically add new networks to the preferred network list". You also have to delete all your existing preferred networks because the airport process seems to lose its mind when it tries to connect to a preferred network. My suspicision is that it gets caught in a loop talking to Secureclient.

This may not be a usable workaround for many, it means typing in WEP keys everytime you connect to a WiFi network, or turning off WiFi security, but it is something. It seems like a permanent solution is either an OS X patch of a new version of Secureclient.

Hi Tony,

I am not confident yet this is a permanent fix, but after I uninstalled SecureClient, setup my preferred wireless network, and the reinstalled SecureClient I haven't had any more runaway airport process problems.

I am not sure if this is a result of defining my preferred network first before installing SecureClient or simply the act of reinstalling SecureClient, but it is solved for me for now.

Checkpoint SecureClient VPN is running fine on my Powerbook G4 17" 1 GHz (Mac OS X 10.4.8). However, I have the same problems with airport running at 95% CPU usage and eating up all physical memory on a MacBook Pro 15" 2.0 GHz (also running 10.4.8). I can't tell whether the problem was there before upgrading to 10.4.8, because I didn't try Checkpoint with previous OS versions. I filed a bug report with Checkpoint and talked to Apple Support over the phone, but no resolution from either side.
