We had an isolated network (10.1.x.x-10.5.x.x) in a remote location for a period of time. Over the last year we installed a T-1 that provides us (our main office (192.168.x.x)) connectivity to that isolated site. The setup was configured as follows:
main office router which contains multiple interfaces(e0-192.168.68.x & s0-10.7.1.x) connects directly to the isloted office router which contains multiple interfaces (s0-10.7.1.x, e0-10.2.1.x & 10.3.1.x).
This setup was put in place to gain access to specific servers on the 10.3.x.x & 10.2.x.x networks. We may also gain access to a couple other device interfaces on the 10.2 and 10.3 networks. However there are other devices that I would like to gain access to within the isolated network. These devices lye on the 10.1.x.x, 10.4.x.x, 10.5.x.x and 10.6.x.x networks. I have not been able to find a way to hit the 1,4,5 & 6 networks from my 192.168.x.x network.
Do I need to add additional interfaces to my isolated router to achive this? If so what is the best way to go about this? Does it require additional HW or is there a way to create virtual interfaces on the router. How would this work when utilizing VLANS?
All help/suggestions are appreciated.
