Hello,
I need help with some routing. I have 3 LANs in Australia (CBR, SYD, and MELB) and 2 international LANs (NY, and LDN). Each network has 3 VLANs, one for Native, one for Admin, and one for Receptionist (data). CBR, NY, and LDN should each have DMZs and any LAN should be able to ping the servers within the DMZs. However, the LANs are not supposed to ping each other. I will configure that with the ASA firewall with access control lists. I need the LANs to at least ping the DMZs. The networks are also connected with nodes in between, which is done for practical purposes. Also, OSPF routing is the main IP routing in this project.
Any help is appreciated.
