Problem with Mac OS Client


I have a PowerPC (PPC) Mac Mini with which I'm trying to contact a VPN3000 private network.

Under Windows XP, the connection works fine, I get an IP address, a virtual adapter appears under "ipconfig" and I can contact the host I need to get to.

Under Mac OS 10.4.8 (PPC) with VPNclient 4.9.0050, it seems to connect, but I can't contact the client. It appears that no routes are setup, nor a virtual adapter. Here's the output from "vpnclient" - note the lack of routes..

Can somebody help!? TIA. Tom

Re: Problem with Mac OS Client


I have the same problem as you.

If I use Window XP under Parallels on a Mac Intel machine, I can connect and browse the network correctly, however under Mac OS X, the route seem inconsistent.

Did you find a solution to this problem?

Anyone has a hint on this issue?

Re: Problem with Mac OS Client

I am trying to using VPN client 4.9 on a G5 (dual processor) OSX 10.4.8. I read and reread the instructions. I go to the command line and copy the INI and profiles into the installer.

When I try to open the VPN client I receive "Error 51: Unable to communicate with the VPN subsystem". The only information I can find on Error 51 is that it is a windows error. Some help. I can't even uninstall the software.

Is any one else having this problem?
