I have two internal networks and I cannot Connect/ping 1 from the other. Here's the situation:
Using Verizon Fios w/ActionTec MI424WR router (LAN 192.168.1.1, DHCP 192.168.1.3-10)
Local LAN 1 has SBS 2003 Server with 2 NICS.
NIC1: 192.168.1.2 GWY: 192.168.1.1 -> ActionTec router (connectoin to WAN)
NIC2: 192.168.254.219 GWY: None -> Local LAN 1 (192.168.254.x)
Note: Running ISA 2004 protecting internal network (LAN1) from WAN traffic
Local LAN 2 has Win 2003 Enterprise Server.
NIC: 192.168.0.2 -> Connected to Netgear FVS114 firewall appliance
GWY: 192.168.0.1 (Netgear FVS114)
FVS114 Firewall Appliance
WAN Connection to ActionTec router: 192.168.1.5
LAN Connection to Win2003 Server: 192.168.0.1
I can connect to the Internet from either the 192.168.0.x internal LAN or the 192.168.254.x internal LAN. Everything works except for communication between 2 internal LANs
I cannot figure out how to communicate between the internal LANs. I cannot even ping 192.168.1.5 (Netgear FVS114 WAN port) from the SBS 2003 Server (192.168.1.2 WAN Nic) even though they are on the same subnet.
Question: How can I do this? Add DNS rules on both servers? IP forwarding somehow? Add rules on ISA2004 and/or ActionTec router and/or FVS114 firewall appliance? Other?
Note: I can ping 192.168.1.1 (ActionTec LAN IP) from SBS 2003 (192.168.1.2/192.168.254.219) or Win 2003 (192.168.0.2) Servers. I can ping 192.168.1.5 from the Win2003 Server but not from the SBS 2003 Server. I can ping 192.168.0.1 from the Win2003 Server (192.168.0.2) but not from the SBS 2003 Server (192.168.1.2).
