thanks peter , kevin & phil

my first mod

was to correct /etc/dhcpd.conf with

"option routers 10.0.0.1;"


& the error message to the ping command changed

to

"....... 100% packet loss ....."



I don't know where to add the following.

"default via 10.0.0.1 dev eth0;"

Thanks for your help

Roger

Roger,

It depends on how you have everything working.  NATing addresses from an
internal network
will not affect your internet connection if done correctly.  All NAT does
is stuff the packets with
a new source address.
Are you sure you have your firewall logging correctly? If you are using
iptables then I would
advise you log your denys see what you are actually doing incorrectly.

Hi all

Firstly is Masquerding  compatible with DHCPD  ??

I am running a home network that works fine with static IP's .

When I  install dhcpd for  dynamic IP's  it works fine except for
connecting to the NET.

On the linux client if you ping the outside world an error  "Network is
unreachable".

There are no errors in /var/log/messages with the failed internet attempt.

I have disabled the "firewall" on the gateway with no difference.

All client machines are affected............
The client machines  I have tried are : Redhat, win98, win2000, winXP
but I still can't connect to the NET. (static IP's  can OK)

My Gateway  is connected via Bigpond ADSL  via  an old alcatel "speed
touch home modem" and also serves DHCPd,   THe IP is 10.0.0.1  ,

My Gateway  runs  "updated" RedHat 9.   ...  networking:  .... PPPOE,
iptables , snort, acid . ................etc

Theres probably some setting somewhere  .... I wish i knew.

TIA

Roger Salisbury
