Woody and cable modem router

[james martinez]

Ok I just got a cable modem router for Christmas so I can share the broadband 
connection with all the pc's in my house. One thing that I am having a 
problem with is when my Woody box is plugged into the router it can not find 
my ISP's mailserver.  Can anyone make some suggestions of what to look at to 
fix this. I am using Kmail as my e-mail client.
