W2K is designed to reliably use only one default gateway at a time with a second one
being configured for "dead gateway detection", so what you are experiencing is the
norm. One alternative may be to create static routes for access to a particular
adapter. The link below explains the configuration of default gateways on multihomed
computers. Also keep in mind that when you enable rras that if you select for vpn
also that "packet filtering" will be configured on one adapter which you can verify
in rras/IP routing/general. Look in the properties of the adapters for input and
output filters. --- Steve
