I have tried looking through the archives, but couldn´t find an answer
to my problem:
I want to use m0n0wall as traffic shaper for the network in my
appartment building. We are currently using a Cisco router, and for the
time being I would like to keep this router running NAT and taking care
of DHCP. The Cisco has the WAN IP from our ISP. The LAN currently uses
I would like to set it up as follows:
Cisco Ethernet1/1 WAN 80.x.x.x
Cisco FastEthernet0/0 LAN 10.1.0.1
m0n0wall WAN ?.?.?.?
m0n0wall LAN ?.?.?.?
PC clients ?.?.?.?
Sofar I have been semi-succesful getting this to work. I used 10.1.0.7
as WAN and 10.1.0.6 as LAN on m0n0wall. Turned off NAT and disabled DHCP
in m0n0. I set up a client machine with IP 10.1.0.9 and 10.1.0.6 as gateway
This way I was able to get an ICMP packet through to the internet. I was
however not able to browse any webpages. I took a look at the routing on
the Cisco. It currently has one route:
ip route 10.1.0.0 255.255.0.0 FastEthernet0/0
I am not too much of a network wiz, but I´m guessing the packet with the
actual webpage data, is being sent back to the wrong place instead of
m0n0wall where it was supposed to? That was my idea anyway, so I added:
ip route 10.1.0.9 255.255.255.255 10.1.0.7
which made me able to browse webpages on the client PC.
This leads me to believe that this setup *could* actually work - but I
simply don't know how to make a similiar routing for all the client
machines on the LAN (10.1.0.0 255.255.0.0).
I tried adding these two routes instead of the existing:
ip route 10.1.0.7 255.255.255.255 FastEthernet0/0
ip route 10.1.0.0 255.255.0.0 10.1.0.7
Now my question is: Would this IP setup work at all, and if so can
anyone tell me what kind of routes I need to add, or anything else I
need to do, in order to make it work?
If this is not the way of doing it, could someone tell me how I can set
Any help is greatly appreciated.
