Another message mentioned adding a route to the "upper" network, but you probably need more. I will assume here that the upper and lower subnets are friendly to each other. Also, that you have not disabled the firewall.
You will need to allow forwarding between the interfaces. I haven't done this (in openwrt / luci), but it will be something like: a) turn off masquerading b) zones wan and lan: input = accept, output = accept, forward = accept c) zone wan -> forwarding to lan d) zone lan -> forwarding to lan If you can configure your comcast router, look for something like static route, add network=192.168.2.0/255.255.255.0 gateway=10.0.0.6. This will cause the router to forward packets for 192.168.2.0/24 to 10.0.0.6. You don't have to touch the hosts. On 9/27/14 10:38 PM, Harry Putnam wrote: > Sorry if this is a bit too unrelated..
