Default Strange network problem

Hello,
Since a few weeks I have a strange network problem.
Using firefox or any other browser I have like 10 seconds between the time I enter an address in the address tab and the display of the page.
It always ends working. Just 10 seconds between click and the display.

This seems not be a dns problem since I get instant responses from any dns query.

Code:
[root@mururoa2 ~]# dig +search www.sun.com

; <<>> DiG 9.4.2 <<>> +search www.sun.com
;; global options:  printcmd
;; Got answer:

Then I looked with traceroute and oups ! Here what I get :

Code:

What's this ? 64 hops and host not reached ... But I did reach it and using firefox the page displays.

Here is the routing table :

Code:
[root@mururoa2 ~]# netstat -rn

And I have this problem only using freebsd 7. I have multi-boot and when I use windows XP or linux I dont have this.

What may cause the problem ?

I'll post later traceroute with linux / XP.
