A client specified that we use two XG-450 firewalls in series for a job that I'm working on now. This is the first time that I'm working on a Sophos firewall. I've configured all of the interfaces, set up a temporary Any-Any rule to reduce headaches during setup, and established our VLANs and Zones. I have not done any of the routing configuration yet.
The firewalls are connected together using two aggregate links. For the time being, the links are on the LAN zone. Outer firewall's link has an IP address of 10.10.10.1, the inner firewall has an IP address of 10.10.10.2.
When I plug my laptop into a management port with a 172.x.x.x address, I am able to successfully ping all of the interfaces on the firewall, however I am unable to ping the 10.10.10.2 interface on the other firewall. I have tried connecting other devices, and I am unable to ping any other devices connected to the firewall from my laptop.
I can ping my laptop, the other firewall, as well as all of the other interfaces connected to the other firewall from the diagnostic screen on the inner firewall.
Is it possible that there is a firewall rule that I am unaware of that is interfering with my ability to ping devices connected to the firewall? Do I need to set up bridges in order to communicate with other devices that are connected to the firewall?
Thanks!
