Hi

I have a Red Hat Linux pc set up, dual booting with 2003. Now, 2003 connects to internet over dsl no probs. Linux is another matter. I set it up as follows.

My pcs all have an address of
IP: 217.155.x.x.
SUB: 255.255.255.248
DG: 10.0.0.138

Router:
IP: 10.0.0.138
SUB: 255.255.255.248

yeah yeah i know, terrible setup! its the only way i could get this crap router to work with my 8ip block from isp though. because the routers address is assinged to the ppp0a port. it won't let me assign it to eth0 as well, rediculous situation i think you'll agree. let be go though it again.

As far as i can see linux must calculate the subnet for the default gateway as 255.0.0.0. and therefore can't access it, windows i assume uses the subnet for the configured ip address, and therefore doesn't have a problem.

Is there a solution to make linux work in this setup? It was suggestted in my orginal thread that i need to use iptables. Is this correct? if so how do i proceed?

Thanks

Paul

Why don't you just install DHCPd?
And at the DHPDd config file you can add a line like "option-router 10.0.0.138"
OR you have to add the gateway-address by hand

sorry i'm a bit of a linux newbie! how would i go about doing this.

Thanks

Well.. I'm a newbie too (I just already solved this question)
You'll have to get DHCP from http://www.isc.org/products/DHCP/
Just install it and edit the DHCPd.conf file in /etc/dhcpd.conf
AND READ THE MANUALS/HOWTO'S/README'S!!!! ==> www.tldp.org

# Example /etc/dhcpd.conf.... You'll have to edit this yourself
ddns-update-style ad-hoc;
default-lease-time 1200;
max-lease-time 9200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
option domain-name-servers ******;
#option domain-name "mydomain.org";
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.100;
}
