Below is a synopsis of my network:
Addr: 192.168.1.0/24, GW: 192.168.1.1(Firewall/Router)
via router at 192.168.1.200 (Cisco)
I have a host at NETWORK_2 with the IP 192.168.2.100. Hosts are reachable between NETWORK_1 and NETWORK_2 with the FW/Router(192.168.1.1) doing the routing.
Host at NETWORK_2 attempts to reach INTERNET via 192.168.1.1 (Firewall/Router), packet filter log shows ALLOWED. However response did not return.
An attempt to test from Internet to Host at NETWORK_2 was received by FW/Router(192.168.1.1) successfully and allowed according to packet filter logs. (NAT: Any->PUBLIC_IP/Any, (dst)192.168.2.100). However did not reach the destination.
My current static route is:
Destination: NETWORK_2 (192.168.2.0/24)
Target: Cisco Router (192.168.1.200)
The policy enables both NETWORK_1 and NETWORK_2 to reach each other. The FW/Router (192.168.1.1) can ping NETWORK_2 successfully.
What else needs to be done?
