Ubuntu – LAN visibility and network sharing

10.10configurationlannetworkingsharing

I have two Ubuntu machines with wifi network cards configured as DHCP interfaces.

machine1:

inet addr:192.168.168.105  Bcast:192.168.168.255  
Mask:255.255.255.0 Gateway: 192.168.168.252

machine2:

inet addr:192.168.168.104  Bcast:192.168.168.255  
Mask:255.255.255.0 Gateway: 192.168.168.252

They are connected to the router:

inet addr: 192.168.168.252

Internet connection from the router is accessible on both of the machines.

How to share files between those two?
I have already tried few ways (eg. samba), but it looks like the machines are not visible to each other:

@machine1$: ping 192.168.168.104
From 192.168.168.105 icmp_seq=1 Destination Host Unreachable

What do I need to configure? Apparmor? Firewall?

The only other problem here might be the WIFI controller. Sometimes these are configured to isolate clients. In other words, you can browse the internet, but you are forbidden to see anything in the same subnet as you - this is the default on many Cisco systems and an option on draytek and presumably others.

If you have access to the WIFI gateway, check for node isolation.
