Hi,

I asked about blueyonder a while ago... Just needed to ask a few more things...

My windows computer burnt out, so the technitions said they will put it on Linux (if I basicly do it for them)

Soooo...

1) How do I make eth1 the default route for all internet dns & IPs?

2) How do I set up dhpcd?

I have to learn this for the install tomorrow morning :|

Thanks,

You need to make sure the router FIB table is setup correctly for all packets.

# ISP_routers_name = your router that has internet access
# eth0 is the interface that connect to that router
route add default gw ISP_routers_name eth0

You all need to allow ip packet forwarding so it can act as a router.
echo 1 > /proc/sys/net/ipv4/ip_forward

Install dhcpd and run "man dhcpd"
blueyonder runs there own DHCP service on the cable modem, so your Linux box doesn't need to do this.

ps. the Modem is tied to the MAC address of the network Card, it won't work unless someone from blueyonder changes it, that's if you have a new NIC.

Then point all the PC's to use the Linux boxes internal IP address as the default router.

The Linux box will also need to do NAT if you don't use External ip address in your internal LAN, like 192.168 10 172.16

Ok...

So, forget IP MASQING for a minute...

Just basic installation...

I plug them modem in to eth1...

At the moment if I type: lynx linuxquestions.org it will try to use eth0 to access this site... I want it to use eth1 instead...

And so, I just forget dhcpcd? or do I run dhcpcd -i eth1?

ok..

dhcpcd is going to get the IP address from there DHCP server.

"dhcpcd uses the network interface eth0 unless an explicit name is specified." from man page

So start with.

# requests IP release
dhcpcd -k
# interface should be 0.0.0.0 waiting for new lease.
dhcpcd eth1
# requests new lease on interface eth1.


I don't know if the syntax is correct as I never use DHCP on Linux boxes, due to the lack of security in authentication.
