Hello,

I just installed and configured Devil Linux and has connectivity to the internet. I can ping google.com.

eth0 is the WAN ( connected to plain cable modem )
eth1 is the LAN ( connected to a PC )

DHCP is turned on for eth1 to hand out IP's on the LAN.

The PC coonected to LAN has no internet connection but gets this..
TCP/IP info of PC
IP: 192.168.1.100
Sub: 255.255.255.0
Gateway: 192.168.1.254
I can ping the routers IP ( 23.25.17.211.86)

The Devil Linux router gets something like this dynamically from the ISP..( I made this up because the whole world could see this)
This is very similier though..
IP: 23.25.17.211.86
Sub: 255.255.252.0
GW: 23.25.17.210.1

I saw the documentation for adding routes in the network config files but I have no idea if I'm supposed to add routes in both eth0 or eth1 file or what.

Im tryinf to get this router going but I'm stuck.

Can you try to use zeroshell?

Thanks Keruskerfuerst, I will do that.

The Devil Linux router can ping google.com but the PC connected to the LAN port can't

I enabled the firewall. Now the PC on the LAN port (eth1) has internet connectivity. I learned that the routing is done automatically. No modify the routes because I just have one labn segment.
But hostnames are not being resolved on the internet. The PC can ping IP's but not the names.

Example,
On the PC I can't ping google.com but can ping the IP address of google.com.

I have DNS BIND started on the Devil Linux router.

Now on the Devil Linux router..
Do I have to make entries in a config file somewhere?
Do I have to do anything with dnsmasque?

What does the Win PC have for a "DNS Server"?
(cmd: ipconfig/all)

p.s. I googled:
network debug tutorial windows|linux

to find some tools, esp. like
netstat -rn

The PC has 192.168.1.1 for DNS. Which was dynamically retrieved from DHCP on Devil Linux router.

I forgot to mention: I'm sticking with Devil Linux.Period.

How did you "enable the firewall"? Per http://www.devil-linux.org/documenta...ml#idp12045824 ?
The next section (table 1.4) had me confused by saying:
"NOTE: for a DHCP server you need to assign a static IP address."
but I'm guessing this means the LAN (not WAN/ISP which is dynamic) side.
'worst case', you could post all your config choices here... ;-(

Maybe, VERY 'maybe', it does need something else "enabled", as in:
https://wiki.openwrt.org/doc/howto/dhcp.dnsmasq (& maybe restart some daemon)
The more I google, the more it seems to be dnsmasq.conf (my wild guess tho)
( https://mike632t.wordpress.com/2013/...reless-router/ )
Obscure deep troubleshooting: tcpdump dns req pkts & strace dhcpd process
Here's a ridiculous kluge that might/likely work: configure the *Win PC OS* to use the *real DNS* address (that the Linux uses, instead of the router box 192.168.1.1 ; Linux should blindly forwarded to ISP...)

Forgive my trying to help when I'm not experienced in this particular area.
(Also, I do understand that changing to another distro would be like throwing out a puzzle simply because it's not yet complete;-) It just needs another piece to be put in place!
Please do post the exact/detailed solution, to help others in the future. Thanks & best wishes.

When the firewall box gets an IP from the ISP, it should also get DNS server addresses. It could be that tcp/udp port 53 is blocked, and even though DNS servers are listed in the configuration, the box cannot communicate with them. OR the firewall box might be configured to use local DNS servers. You can try these DNS servers to check things out: 8.8.8.8 and 8.8.4.4. Because of how the DNS system works, you need 2 servers.

Jjanel,
Devil Linux has a easy to use setup program in which you can enable the firewall.
Also, for the WAN side you don't need a static IP but instead you CAN set eth0 for DHCP which will retreive all TCP/IP from your ISP.
Thanks for your help.

AwesomeMachine,
Thanks for leading me in the right direction. I decided to use the same DNS servers listed in /etc/resolv.conf for the DNS entries in the DHCP setup program included in Devil Linux. Those DNS Servers listed in resolv.conf where the ones provided by my ISP. Now all PC's on the LAN can resolv external hostnames. Problem solved!

I'm lovin'it.
