I currently have an 837 with two subnets off it, one attached to the eth0 interface and one attached to the eth2 interface, each one has a small switch and a bunch of pcs behind.
The subnet attached to the eth0 is 192.168.10.0/24 and 192.168.64.0/24 on eth2 and there is some static nat setup for servers behind each. This works fine with no problems, both subnets can get out onto the internet and pcs on each can route to the other. I have been asked to do a similar setup for a customer but using an 878 router.
The problem i have with my limited knowledge is that the 878 doesn't have any ethernet interfaces so i would like to know if the same or similar is possible using VLANs, i have made the assumption that VLAN1 interface which currently has an IP address can be configure to be used by only one of the fast ethernet ports and that i can create another VLAN interface and configure another fast ethernet port to only use that one and attached to each one of these have a switch.
I'm hoping that this sort of setup will alow me to have the two subnets with server(s) in each that can have static nat. I appreciate any help in advance.
