Hello Michael,

Thanks for your help. I was hoping for something simpler than that. I used 
10.10.10.10 as a hypothetical internet address. Let say its  
216.111.222.333. I am able to telnet and ping to 216.111.222.333. But I 
cannot ftp and http to this address from my internal masqed hosts. Any help 
is appreciated.

Regards,
Vernon
