ifconfig wi0 on my Dell 8000 (two days old cvsup) shows that the WLAN is up
on the right SSID, adhoc mode, 2Mbit. But the interface didn|t get the
address from dhclient. I stopped dhclient and set the address manually.
Set default route manually.

When I ping the peer point, my gateway machine, I get sendto: host is down.

At the same time I see reachtion via tcpdump on the peer (gateway)
side:
# tcpdump: listening on wi0

The arp requests are the consequence of the ping from my
notbook to the peer, while the icmp: echo request is the
ping from my notebook.

Could it be a firewall issue? I have not changed anything and have
firewall_enable=NO in rc.conf.

Any ideas?
