SafeNet 10 VPN client

Hi,

I have a MS Win 2003 server setup as a VPN server (RRAS) allowing only
L2TP/IPsec connections. Certificates provided by a Win 2003 srv CA on my
LAN.

A couple of my users need to access another site's VPN too, but they use
another VPN gateway make/model. I know that I can use the SafeNet
SoftRemoteLT v.10 client to connect to their site (this is what they tell
me) but it will disable the MS Dial-up Networking client when it is
installed. This would mean my users would lost the ability to connect to my
LAN unless..... SafeNet SoftRemoteLT can be used to connect to a MS RRAS
server??

I was hoping someone might have tried this because the client is very widely
used. If not, can the MS Dial-up Networking client be used to connect to
other (not MS) gateway servers for L2TP/IPsec connections?

TIA,

Jarryd
