I was looking for a great NAT server prefrably one of each:


1- Linux Based
2- Hardware Based
3- Runs On windows platform (other than wingate)


there is something else i was wondering-

if i have a nat installed as following

40.40.40.40:80 >>fw-to>> 10.10.10.10:81

will all the other ports be closed ?

another thing that worries me is... on the NAT server lets say wingate.. i have 2 network cards ... one that is 40.40.40.40 and the other 10.10.10.9 .. should a hacker be smart enough to connect to 40.40.40.40 and then use the 10.10.10.9 on the pc to gain access to the class A network ?

i hope i am not asking for too much in one single post


thanx for all your replies.

best regards ...
