linux as router/gateway/firewall to dsl-router
I set up a network like this:
eth0 dsl_router int 10.0.0.138
eth1 linux_router int 10.0.0.161 to switch
eth0 linux_router ext 10.0.0.151 to dsl_router gateway 10.0.0.138
eth0 box 10.0.0.150 gateway 10.0.0.161
I statically assigned ip-addresses to the box and the linux router
both it´s networkcards.
When I ping from box to linux router (10.0.0.151 and 10.0.0.161) both
of them work.
Pinging from linux_router to box is ok.
But only when I use:
´ifconfig eth1 down ifconfig eth0´ up the linux_router is able to ping to dsl_router (or otherwise to linux box).
I can bring up both interfaces, but I am only able to ping through one of them depending on which one I bring up first.
With my linux box I can reach both cards on linux_router, but not my dsl_router.
I run Suse 10.0 on linux_router, within yast configuration I configured routing with default gateway 10.0.0.161 (this is correct I think for it is the gateway for boxes), ip-forwarding on
For now I used the speedtouch for routing, I figured out I can upload a template for the
speedtouch so it acts as bidged ethernet device.
But with both of them routing I can´t connect a box to the speedtouch, it must be possible
I think, does anyone has an idea?
Is two routers not wise to choose, or doesn´t matter? (hard configuration or so)
Should I have a different network e.g. 10.0.1.x (or so) for int network?
My main questions: How to give the box internet through the linux_router and through the speedtouch dsl_router?
Are there important configurations wich I could have forgotten?
I stopped the firewall and tried the ping´s again but still didn´t work. Or does the firewall have to run with some adapted configuration?
change your router subnet or your LAN subnet .in case of using same subnet to your lan and router you may have configure bride-utility
i think so !
