Ok i been fooling around with this, and suspect I am missing something dumb... I have the following SOHO network configuration -
Internet | Router A 169.254.1.1 | |-----169.254.1.200 Router B 192.168.20.1 --------- 192.168.20.100 Machine A | 169.254.1.100 (eth0) OpenSuSE Gateway Machine with SuSEFirewall 192.168.10.1 (eth1) | | 192.168.10.20 Machine B
So how do I set up the SuSEFirewall and the network routing tables on the OpenSuSE Gateway to allow Machine B to see Machine A? I did set up a route in the Routing Table in YaST2 for the network interfaces as follows -
Destination 192.168.20.0 Genmask 255.255.255.0 Gateway 169.254.1.200 Device eth0
The gateway address for Machine A is set to 192.168.20.1 The gateway address for Machine B is set to 192.168.10.1 The gateway address for the OpenSuSE Gateway Machine is set to 169.254.1.1
So far I have been unable to get Machine B to even ping Machine A. Is the SuSEFirewall interfering and if so what do I have to do to make it behave? I tried a few things with it also, but so far no joy.
Gotta be something dumb I am missing, appreciate and thanks in advance for a bit of help..
Marc... You need to rephrase your question:
You have 2 separate default non-routable networks setup with a suse gateway router between them and you're asking how to have the suse gateway router route the default non-routable traffic between them.
I don't know how to override the default lack of routing of 169.254.x.x and 192.168.x.x addresses in the suse gateway router, but I'd be shocked if you can't be done easily. Hopefully someone else knows how to override the default behavior and route those IPs.
fyi: This is not a "dumb" question. You have setup a more complex network, but companies do similar things all the time. If a company is lucky enough to have their own class A, class B, class C's, Then they can do it all with routable IPs.
The reality today is most companies don't have that luxury, so the do use multiple non-routable networks so they can do things such as have a 10.x.x.x for the main network and a 192.168.x.x for a wireless guest network, etc.
To accommodate that routers have override options to allow those IP ranges to be routed. I just have never been the one responsible for setting that up, so I don't know any details of how to do the override.

Thanks Togan, James, Greg for your replies. Togan, James, you both pointed out the same thing, which I was kinda afraid of, that the 169.254.x.x network is a non-routable IP address range. I have encountered issues with this before and so far have not come up with a good answer. My trouble is that the devices on this network consist of some Motorola Canopy wireless access points and subscriber modules. These sit on towers and are not easily accessible, and the trouble is that if there is a power cycle, then these devices reboot and come up with a default IP address on the 169.254.x.x network. This is how I get my internet access to my SOHO network at home/business, I live way out in the woods! (I have tried to look into upgrading the firmware of these devices but so far no joy in figuring out how to do so, in order to get around this problem.) I set up the router B for the 192.168.20.x network to handle smart cell phones and some associated devices and get them off of the gateway computer and internal network (192.168.10.x) used for my home/business computers and servers. This is an attempt to improve phone call drops and intermittent issues we were having when the cell phones were on the same network as all the rest of our computers. Greg - Yes I think you see/understand what I am trying to do with having a separate network set up outside of my gateway computer. It sounds to me that from what you are saying, even if I could switch the 169.254.xx network address over to something like a 10.x.x.x network I would still have routing problems. Hmmmm, anyone got any ideas on how to go about solving this? Suggestions on wireless routers I can use? Right now I am using Rosewill wireless routers and I don't see any settings that allow me to override routing rules and still provide NAT capabilities.
