If you dont mind configuring all your users then you can use a SOCKS proxy 
on the secure FreeBSD server.
I use 'nylon' from ports for this purpose quite effectively (although only for a home
network of up to about 5 clients)

Another option is to simply route the MSN/ICQ traffic across to the other server.
Either route everything through the ipsec link to the other server (ie make it your
default route) or if you know the MSN/ICQ server IP range you can just route 
the specific subnets.

Regards,

Tony
