>I have a LAN conected to the internet vía Proxy. In my server i have to LAN cards, one with public IP address (connected directly to the internet), and the other with a private IP, wich i use to connect to the LAN. I have donwloaded the trial version of Wingate proxy server. I have configured the server to use DHCP, and every pc client to obtain an automatic IP address, also the client pc get an automatic Gateway and DNS. Well i have my LAN working to internet, but only if i use the Internet Client of Wingate. And i have read that you can also conect to the Internet useing NAT, and wingate supports NAT. I have enabled NAT in the wingate server, but the clients continue without connectin unless you put the client. I really need to put NAT to work, 'cause my company whant's to use NETMEETING, but this is a little complicated unsing a normal proxy, 'cause the protocol that NETMEETING uses. Anyway i have read in the Wingate support page, that NETMEETING should work only by configuring
>NAT. Please if you know of any other step that i maybe miss, or any other way to configure this (hardware or software) please let me know, i will be greatly thankfull.
