I have been working for hours trying to figure out how to configure my firewalls in packet tracer for the pretend hospital network I am building. The cloud pt (internet) is set up with frame relay going to router 1, 2, 3, and 4. from there you have the wireless router connected to the router directly for patient internet access. as you can see there is also a firewall connected which separates the private network of the hospital from the patient network. I am able to ping from any of the private pc's in the network to any other firewall, but unable to ping from private network to private network. Please help!!! There is a picture of the network along with the link to the actual packet tracer network to download, maybe help me troubleshoot the issue. Thank you in advance.
