This is indeed strange.
Changes to the VPN ports configuration usually require a restart. Is it
possible that you failed to notice a "need to restart" alert (monitoring
node, alert tab) after you configured VPN client access?

If this is not the case, I would also like to point you to the VPN clients
solution document at
http://www.microsoft.com/technet/prodtechnol/isa/2004/plan/vpnroamingquarantine.mspx.
Reading the guidelines there usually helps.

Thanks,
 Daphne
