I am installing an ISA570 to replace a failed Juniper Network device and am having a problem with configuration, our internal Network has three other internal routers located on it. The ISA570 will route between the Internet and Network 0. Router A routes between Networks 0,2,3 & 4 and Router B routes between Networks 0 & 5 and Router C routes between Networks 1 & 2. I know it's kind of convoluted, but to change it at this point would require rewiring part of the building, which is not currently possible.
I thought I had everthing configured but the following is happening:
Devices on Network 0 can get out onto the Internet, so the ISA570 is routing correctly between Network 0 and the Internet
Devices on Networks 1,2,3,4 & 5 can ping the ISA570, but can not access the Internet.
A Tracert from devices on the other networks get to the ISA570 and then fails.
