Cisco RV082, Dual connection, 2VLANs

Hi everyone,

I'm having a bit hard times to figure out how to do this configuration.

Currently I have;

- RV082 with DSL as main WAN with Bell for downstairs network(DCHP running on SBS2003; 192.168.100.101-169)

- Hitron cgn2 in Bridge Mode with Linksys WRT 160N for wifi and upstairs network (192.168.100.170 - 190)

What I want to do;

- Connect Rogers Cable to RV082 for failsafe connection if downstairs internet drops. (on WAN2)
- Allow single IP address from upstairs network (192.168.100.171) to downstairs network through RV082 (Other Wifi Users cannot access downstairs network (except 1 Laptop)

RV082 (192.168.100.100 - 169)
WAN1 Bell
WAN2 Rogers
LAN1 Downstairs Network
LAN2 WRT160N LAN1

WRT160N (192.168.100.170 - 190)
WAN Hitron Modem WAN
LAN2 Upstairs Network
WiFi around the house

Thanks in advance on your suggestions/guidelines.

Given the lack of configurability in the stock firmware of the RV082 and the Linksys WRT160N, I'd say you cannot
do what you want -- you'd need at least a fully-configurable Cisco IOS device to limit NAT'ing like that.

Otherwise, most of the expertise here is in the aforementioned IOS and enterprise-level side of things, rather
than the Small Business and ex-Linksys by Cisco side of things.

Thanks for the reply.

I also have a Cisco 871W in that location (its not in use at the moment) Do you think I can do what I want with 871W?

Depends on the IOS features available but I'm thinking with a little of thought and some NAT and appropriate ACL's, this would be do-able

As markysharkey See Profile says, if you've the right IOS version, this should be easy enough to do in rough pseudocode

ip nat inside source list [your NAT ACL] interface [wan interface to Rogers] overload
 
[your NAT ACL]
permit 192.168.100.100 255.255.255.224
permit 192.168.100.170 255.255.255.255
deny any any
