Eth address

Hi - I wanted to use mangoh green with the plain ETH only (for a moment).
My local network is, with router at

I set up the ETH to static address I set it frist
I can ssh to it. I can ping it from outside and I can ping computers on my network from inside.
iptables are empty - all policies set to ACCEPT.

HOWEVER: I can’t ping the router ( from the box!
And without router/gateway I can’t connect to the Internet.

I even did experiment setting ETH from DHCP (which is offered by the router. And the box GOT the address, settings, but still was not able to ping the router or get outside.

I’m a bit puzzled by this. Is there anything else I could possible check?

Best regards,

Hi Miroslav,
Did you add ‘gateway’ IP ( gateway - IP of your router ). You will find sample settings below.

iface eth0 inet static
hwaddress ether 00:00:00:00:00:00



Hi Bartek,

of course I added it. Look at this shell session:

root@swi-mdm9x28-wp:~# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 46:53:F2:C7:41:2E  
              inet addr:  Bcast:  Mask:

              RX packets:185 errors:0 dropped:0 overruns:0 frame:0
              TX packets:200 errors:0 dropped:0 overruns:0 carrier:0

root@swi-mdm9x28-wp:~# iptables -L -n
Chain INPUT (policy ACCEPT)

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination     

And I’m connected (ssh) via eth. ipv6 is disabled.

I can ping - another device on the network. I can obviously ping my laptop (77).
But I can’t ping - the router. Moreover. It has port 80 open (administration) and this happen when I try to connect:

root@swi-mdm9x28-wp:~# telnet 80
telnet: can't connect to remote host ( Protocol error

There is no connection to this particular IP because of some weird reasons. That is why it is so puzzling.

Any ideas?

Best regards,
