However, I do desparetely need some help here. My name is Johnny Dang. I have been running RedHat Linux 6.1, 6.2 and 7.0.... I use it as a Router/Firewall/IPMASQUERADING for a small church in Silver Spring... I don't want them to pay for Microsoft since they don't make money out of it. Anyway, I am getting with the anarchy of Linux so overheard of FreeBSD, I decide to subcribce (rather than download for free--I want to keep the FreeBSD alive) the 4.2 CDs. To be honest, I am in love with at the first moment...I DO NOT WANT TO BACK TO REDHAT.... Like I mention above, I try to reset the new FreeBSD as a ROUTER/Firewall/NATD in this case. I did make the NATD work (all PC in the internal now have access to the Internet--eventhough it is a wide opened firewall)...The problem I have now is I cannot redirect the traffic from outside to the inside. For example, I will have another FreeBSD running WWW amd Mail server. I cannot redirect the tcp port 80, 443, nor 22, 23 to another internal PC. I read the NATD manual, and IPFW manual.. Still, I have no luck. I read all the FreeBSD diary, other web sites. Still have no luck. Can you all help me? I need steps by steps, or any good book about NATD and IPFW? Also, should I move to IP-NAT or IP-Filter? Can I use IPFWADM from Linux or IPCHAINS? Please help. I try to IP alias last night until 2:00AM with no luck... Here is my network: Internet ------ Free BSD (two NICS)-------------------------->PC 1 (WWW + Mail Server)---------PC 2- (telnet)-----Local LAN IP1: 123.123.123.123 IP 192.168.1.2 IP 192.168.1.5 192.168.1.10-25 IP2: 192.168.1.1 IPFIREWALL IPDIVERT I can not run the most basic IPFW script (wide open)... I can wait to read and change the script later... But I need to know how to redirect the traffic from outside (ports 80, 443, 22, 23, and 25) to the local LAN... Please help me. A good script, a web site, a white paper, or even a good book... Thanks for your help. ------_=_NextPart_001_01C0A316.F0FA214A Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable IPFW and NATD--Please help me!
