@ jester
Thanks for your quick reply.
As I understand (pls. correct me if I'm wrong) I need a PC with 2 NIC's , one for local lan and one for outside ( I have a radio modem ). I don't need Web and mail server so I can use Private server and gateway mode. I need basic Internet access (http, https, ftp, POP3, etc ) for all my lan PC's, so I need to config one nic for local and another for Internet. I assume the SME gateway will make all for me to access the internet from lan. It is one thing that I don't know : my ISP give me a static IP , subnetmask , gateway ( ok till now ) and 2 DNS adress that I don't know if and where to put, maybe this are only usefull if I need Web server and Mail server.
Sorry for the silly questions but I'm new on servers , especially Linux.
Best regards
alex
