We recently moved from a Watchguard Firebox firewall to a Juniper SSG 320. We have 7 total locations/branches and they all can access the Internet via the Juniper. The Juniper has static routing entries for each of the branches. I can ping any system at any branch from the main office and I can ping anything at any branch from any other branch... so it appears routing is set up. Here is the problem:
When users attempt to utilize our Intranet or other services hosted at our main branch (where the Juniper is located and is the default route) they are unable to access anything. I can ping, but I cannot ssh or telnet or anything else. If I enter static routes to each of the branches in the servers everything works as it should.
Is there a setting in the Juniper I am missing? Could there be an ARP issue?
As a side note, I still have the Watchguard online (with a different internal IP address than it used to have) and I can still get to the Internet (via a different ISP which we are cancelling).
