Netmask? Always indicate your ip-address as <IP-address>/<CIDR>. > Also i can ping the two pc from each other, but from ubuntu i cannot ping > the router or any internet address.

Two things to do: * Check your firewall log, if no logging is done, add log rules to see where packets are caught. * Try sniffing on the interfaces on the BSD box with tcpdump or snort. Is the DSL smart enough to figure out to return the icmp? Maybe it doesn't guess that a reply should go out on the same interface as the request was received: The dsl does likely not know about your network between your two machines, so instead of returning the ping on the wireless interface that received the ping it is sent off to the default gateway which goes to the internet. If that is the case you must add routing to your 192.168.0.0/24 network on the DSL.
