Microsoft ISA L2TP IPSec with certs

[haktan]

Hi,

We have quite big troubles with getting Mac-clients (Leopard)to connect to a Microsoft ISA Server for VPN. It seems that Leopard/OSX supports L2TP with certificates, but we have not been able to import certificates to the Mac and make it show up in the machine certificates.

Anyone succedded to use L2TP IP Sec with Microsoft ISA as server and Leopard/Mac as client? If yes, please tell how in details - especially how to generate/import/export certifcates ind the respective systems.

Thanks in advance & Best regards
