1 router brings internet into the house(actiontec brand from verizon). it provides addresses in the range of 192.168.1.2 to 192.168.1.254. the first router also provides wireless access as well as access to the net for some devices (web server, ftp server,mail server)

another router(netgear) is set up with its wan port as 192.168.1.2. the second router provides addresses from 192.168.10.2 to 192.168.10.254. the devices connected to second router can surf the net and access each other.

I would like the devices attached to the first router and the second router to be able to communicate. My first experiment was to try and access the second subnet from the first. A device with the ip 192.168.1.5 could not see or ping anything on the second network behind the second router or even the router itself (192.168.1.2). I tried setting the mask for the first router to 255.255.0.0 but that did not help.


any suggestions?

The first router need a route to 192.168.10.0. Add this route with a next hop of 192.168.1.2. Keep in mind the second router will need to be able to allow this access. There are very few reasons you would want to use the second router in a routing/NAT mode as you have done. Don't use the WAN port of the second router and use the lan port instead and disable DHCP on the second router.

You have to imagine that what ever is on the first Router is like an Internet to the second Router.

Thus you can by easily go from the secure (second zone) to the first Zone.

To go from the first zone to the second zone (against the second NAT) you have to set a program like UltraVNC through the second Router in the same manner that you control a LAN from the Internet.

Look at this page, http://www.ezlan.net/vnc.html

Are you using the second router with NAT disabled? With a decent router, you can route on to the second subnet while keeping the firewall active. You will need to configure the firewall rules by hand though. Double NAT'ing is usually a bad idea that can break some applications.

I think Spidey was talking about a *real* router, cisco and whatever. I'm not sure about the options of ww-drt and tomato this may be an option if you have a compatible router.
