Eircom Broadband 
Cayman 3341 DSL Router via Ethernet

Trying to sort out a problem that I have with eircom broadband. My
cayman 3341 does work but the response I am getting is best described as
sluggish..

Initially I thought the problem was DNS related but a bash nslookup took
milli-seconds. When I would go to the browser it would take a page 30
seconds to start loading but a download would come down at 50K/sec. 

I have looked at static routes ... they are fine, all going to default
gateway. when I do an ifconfig I get the following


ifconfig -a

What worried me is this sit0 device ipv6 in ipv4...

Any ideas appreciated...
