Problem with MT

Wannabe · Tue Mar 18, 2008 7:47 am

I have an adsl-modem attached to MT box with simple bridged scheme like that:

(WAN) --- <ADSL> --- <MT> --- (LAN 192.168.1.0/24 hotspot)

It worked fine, but now I need to set up an additional computer in network as follow:

(WAN) --- <ADSL> --- <HUB> --- <MT> --- (LAN 192.168.1.0/24 hotspot) 
       92.168.0.1/24   |      192.168.0.2/24
                     <PC>
                192.168.0.3/24

The gateway parameter for 192.168.0.3 box is 192.168.0.2 (MT box).
Hotspot on MT allowed only on LAN interface.
Firewall on 192.168.0.3 pc is disabled.

When I try ping anything from 192.168.0.3 PC, this happens:

user@pc:~$ ping 192.168.0.2
PING 192.168.0.2 (192.168.0.2) 56(84) bytes of data.

From 192.168.0.2 icmp_seq=4 Dest Unreachable; Bad Code: 9
From 192.168.0.2 icmp_seq=5 Dest Unreachable; Bad Code: 9

From MT box, I cannot ping 192.168.0.3 pc:

[admin@mt1] > ping 192.168.0.3
192.168.0.3 ping timeout

From LAN computer (authorized with hotspot):

user1@laptop:~$ ping 192.168.0.3
PING 192.168.0.3 (192.168.15.3) 56(84) bytes of data.

From 192.168.0.2 icmp_seq=11 Destination Host Unreachable
From 192.168.0.2 icmp_seq=12 Destination Host Unreachable

How can I access to WAN from 192.168.0.3 through 192.160.0.2 (MT box)? Is there any problem with bridged ADSL-MT-connection?

If you remove your PC Box's default gateway, can you then ping the MT box and the ADSL router? If not, the problem is on your PC, but I doubt it.

I would really suggest adding another ethernet interface on your MT and connect your PC to that interface with a DHCP server.

From what you wrote in your forum post, everything seems to be correct. Perhaps more info would help us a bit.
