We use BM 3.8. We are looking to move from one ISP to another without
causing downtime. I added another card in the server and got it
configured with the new ISP address, and gateway.
However I can only ping the ipaddress of the new provider when I disable
the card that services the provider we are trying to move off of.
All filters are off and NAT implicite is disabled.

Is it possible to have to ISPs supported on a single box. I am thinking
it is and that I missed something.
The goal would be to makes sure the services we have exposed on the old
address will work at the same time as the new address and then change
DNS and then kill the old connection.
