I have three PA220s, let's call them
PA220-A
PA220-B
PA220-C
They are connected in the following manner:
PA220-A ---- PA220-B ----- PA220-C
All three have an Inside and Outside Interface. All the Outside interfaces are connected via a Layer2 network. My IP addressing, let's say it's the following:
PA220-A - Outisde - 172.16.10.1
PA220-A - Inside 192.168.0.0/24 (192.168.0.1/24)
PA220-B - Outside - 172.16.10.2
PA220-B - Inside - 192.168.1.0/24 (192.168.1.1/24)
PA220-C - Outside - 192.168.1.0/24 (192.168.1.2/24)
PA220-C - Inside - 192.168.2.0/24 (192.168.2.1/24)
When I'm pinging from the outside interface of PA220-C, I can traverse the entire network into PA220-A, and vice versa. But when I try to ping from PA220-C inside network, I get a timeout. But I can ping between the Inside and Outside interface of PA220-C. I belive it's a routing issue, but I'm banging my head against the wall trying to figure this one out.
If anyone has any suggestions on areas to look at, that would be helpful.
It's also noted that I have deleted all firewall rules on all three PA220, just to test connectivity first. I have also changed the default rules to allow all traffic regardless.
