I'm working on a project for a networking class. In VMWare Workstation, I have to set up a 2008 r2 server with DHCP reservations for 2 clients on separate subnets and have them ping each other.

Here is the output of the route print command:

My problem is that although I have set up both dynamic and persistent static routes in my r2 server, neither of the clients can ping even the NIC outside its own subnet. For example Client A can ping the NIC at 10.0.0.2 and vice-versa, but it gets a general transmit failure when it tries to ping the card at 223.6.6.2, let alone trying to ping the other client.

I have completely disabled the firewalls on all machines and anything else I could think of, without success. What am I missing?

Edit: Since posting this, I also noticed that the default gateways on my 2 NICs keep getting zeroed out. Does anyone know a fix for this?

1 Answer 1

you can only set one default gateway per machine. if you want to route out traffic on nic 2 to another network you had to set static routes for this networks. so just set a DG eihter on nic 1 or nic 2 and to the rest with static routes
