colocation

I have some servers at a colocation. They've given us an IP range,subnet,and gateway. Now we have run out of IP's and they've given us a new range of IP's 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 IP's 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.
