Hey, I am sure this question is going to seem trivial to everyone here .. but I will ask anyway. I want to get outlook to work on my inside box .... I have it all set up correctly, but it can't find the pop / smtp servers ... I ran ethereal to see what the problem was ... When I try to connect I get 3 requests source 10.0.0.2 dest 10.0.0.255 Protocol NBNS source and dest ports: 137 and I get no reply's ... ( well, I get an arp request after the 3rd try ...) Any ideas how to get this working ? BTW, I am using IPTables Thanks Peter Marshall
