Does anyone have a suggestion for a IPSEC based client with (preferably) KDE based interface?

I have tried kvpnc with racoon and openswan, and it's way to buggy/doesn't work (racoon can't parse the generated configuration and it doesn't save all changes and so on).

I have tried ShrewSoft VPN client (Shrew Soft Inc : Home), but the virtual (tap0) interface messes up the broadcast and IP addresses.

So.. Anyone have any other suggestions?
