Hi Teco,
Thanks for your anser.
I'm typing the IP address as http address so it should not be DNS
related. IPv6 isn't enable on rc.conf and not configure in olsrd.conf. I
also tryed with both pf on and off so it's also not firewall related.
Here the output of tcp dump, we can see the request was made at 15:27:49
and I got httpinfo page at 15:29:02. Maybe somebody will understand this
output better than me.

That not a big problem but it strange the answer is so long to get from
httpinfo. I will also try txtinfo to check if the same happen
Thanks
