I ran a traceroute from the director box to the webserver and the
results are wierd, max 30 hops:
 1  * * *
 2  * * *
 3  * * *
 4  * * *
 5  * * *
 6  * * *
 7  * * *
 8  * * *
 9  * * *
10  * * *
11  * * *
12  * * *
13  * * *
14  * * *
15  * * *
16  * * *
17  * * *
18  * * *
19  * * *
20  * * *
21  * * *
22  * * *
23  * * *
24  * * *
25  * * *
26  * * *
27  * * *
28  * * *
29  * * *
30  * * *

But when I traceroute the default gateway i get:

1  home (192.168.1.254)  1.133 ms  0.793 ms  1.607 ms

might this have to do with the problem?
