Network Issues

Ok i have a 2 router setup

Router A(10.1.1.1) is connected to a windows box (10.1.1.3) and also is connected to router B (10.1.1.2)

Router B's internal IP is 192.168.2.1
Router B is connected to 4 other machines

I have added the static route to my windows box (10.1.1.3)using
"route add 192.168.2.0 mask 255.255.255.0 10.1.1.2 -p"

When I run a ping I cannot ping the router B's external port (10.1.1.2) but can ping its internal port (192.168.2.1)

Router B is being told to forward SSH packets and http packets to my unix server (192.168.2.12)

I cannot ping or ssh to any machine(including my unix server) on router B's subnet.

Anybody know how I could go about getting this to work?

sanity check: do you need more than one router? Chances are you don't.

if you hook them up to the same router, all your problems go away.

Outside of the fact it looks like you are stuck behind a router to begin with. 10.x.x.x are private IP ranges.

If you are going to connect two routers together on the lan side, you don't need two. use one and buy a switch.

I was wondering why you'd mix-n-match 10.x.x.x and 192.168.x.x subnet IP ranges. That'd make masking a pain, and give DHCP a sh1t-fit.

What FlipTW said: can't think of a reason to run two routers.

I have configured my brothers house with two routers(6,000 sqft house)

Orginally it was one router w/dsl)1st flr only), then later he got happy with some additional Computers/XBox. Then at the same time he went from dsl to cable. soo

Basement(fully furnished)
RG6 cable drop - Cable modem

Linksys Router w/4 Port switch (this was added later)
192.168.1.1 - GATEWAY enabled, DHCP Server Enabled (begin at x.x.x.100)

-- XBOX
-- 2 XP Machines

Main Floor/Above

Linksys Wireless Router w/4port switch
192.168.1.2 - ROUTER enabled, DHCP server Disabled

-- 2 Wireless Laptops
-- 3 XP Machines (spaning 2 floors)
-- Wireless Repeater (third floor)

No other configuration is feasable nor cost effective, and a switch.... not happening folks... If you know anything about plant layouts and the description above then you would not even suggest it.. But seriously Xeon WTF are you doing... with all that 10xxxxx stuff

I run three routers! Two are hooked to a switch connected to the cable modem (I have two IPs), and are also hooked to each other LAN-side so I can talk to my desktop from the laptop without having to open ports. Router #3 is a 54g wireless router in the living room to connect my laptop to. This connects to one of the wired routers via a powerline link, because I can't get a signal with it in the computer room (signal seems to suck, and it has to go right through the fireplace).

But I don't mix Class B and Class C subnets, I just have two Class Cs that I use.

I have 2 routers because of the distance between the 7 PC's in the house.
