2 Subnets on 1 Interface w/ NetScreen 25
Posted on 2006-05-31
Hi I'm running a NetScreen 25 w/ 5.3r2 software.
I have an existing subnet from my ISP that we outgrew. The ISP assigned us an additional subnet because no adjacent subnets are available. We have to keep both subnets because we have a ton of production equipment on the origonal subnet.
We have talked to Juniper and they told us this is possible using a Sub-Interface, but we haven't got it to work yet. The problem is I cannot find any documentation to provide me with details as to how it works.
As it stands now I have a sub-if with and IP on the new subnet. When I try to assign an address from the new subnet to a device, the device is unable to ping anything. Not the gateway, not another device on the same subnet, not a device on the origional subnet, and not on the internet. I think the problem must be an issue with the firewall understanding the subnet or maybe even a policy issue.
Thanks in advance,
