I have some servers at a colocation. They've given us an IP range, subnet and gateway. Now we have run out of IP addresses and they've given us a new range of IPs but with a different subnet and gateway.
We have a Juniper NetScreen firewall and a load balancer, and I am not sure how to proceed in order to be able to use these new IPS that are on a different subnet.
Do I need to setup a new VLAN? on our firewall?
I tried adding one of the new IPs on one of our servers, with the new subnet and gateway. I could ping the alternate gateway, but could not ping the assigned IP from outside or from inside.
