 How To Add a Subnet? (I thought it was going to be easy)
We (we'll call ourselves Company A) are currently running Checkpoint Firewall NG.
Another company (call them Company B) has moved into our office and we want to put them on a different subnet. We are using 10.0.1.x and want to put Company B on 10.0.50.x.
The IP address (interface) we are using for our CheckPoint Gateway is 10.0.1.2, and we also have a network defined for 10.0.1.0. To accomodate Company B, we added 10.0.50.1 as an additional interface on the CP Gateway, and have added a new network for 10.0.50.0. I added Company B's network to the Rule Base, verified it, and it checks out OK. In addition, pinging to 10.0.50.1 from our computers works fine.
However, when we changed the IP addresses on Company B's servers using 10.0.50.x addresses, we were unable to ping 10.0.50.1. Likewise, sending a ping from the firewall to any Company B server was unsuccessful. However, pinging to 10.0.50.1 from our computers still works!
Is there something I am missing or forgot to do? I thought that I would have to manually add a route to the routing table, but it looks like 10.0.50.0 is already in there.
Any response would be greatly appreciated.  |
