Re: Two networking cards

Ray,
Ok here is the thing you have a gateway of 155.57.19.254 Is this your
internet router?
do the workstations have this as their default gateway?
What is the gateway on the workstations in your 2 subnets?
This is key to understanding how the traffic is routed and by what.

If you want performance, load balancing or redundancy then you need to use
network teaming.
This gives you 1 virtual IP address over multiple network cards.
