I am at a loss with this setup, any suggestions are welcome: Details: Running Freebsd 4.3-RELEASE, ipfw, natd, dhcpd, and gateway is enabled I'm running this box with two NIC's and an Emerging Technologies card that functions as a router. The Emerging Technologies card (eth0) is the WAN interface, one of the NIC's (fxp1) is the LAN interface. Nothing on the LAN interface can access the internet (via the WAN interface). What I know: 1.) Traffic gets to the FreeBSD box from the WAN interface. 2.) Traffic goes out the WAN interface from the FreeBSD box 3.) Traffic goes out the LAN interface from the FreeBSD box (workstations are assigned ip's via dhcpd therefore telling me that they are seeing the box on the network via the LAN interface), plus I can also ping these boxes when they are assigned an IP 4.) Traffic does NOT go out the WAN interface from the LAN interface (no workstation can reach the net). Problem: Is this a routing issue? Traffic simply isn't being passed from the LAN interface to the WAN interface. My routing tables: % netstat -r -n Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 65.114.176.41 UGSc 6 24630 eth0 65.114.176.41 65.114.176.42 UH 5 2 eth0 127.0.0.1 127.0.0.1 UH 0 4 lo0 192.168.1 link#2 UC 0 0 fxp1 => eth0 is 65.114.176.42 fxp1 is 192.168.1.1 Pertinent details from /etc/rc.conf: gateway_enable="YES" firewall_enable="YES" firewall_type="open" natd_enable="YES" natd_interface="eth0" natd_flags="-f /etc/natd.conf" ipfw details: % ipfw list 00100 allow ip from any to any via lo0 00200 deny ip from any to 127.0.0.0/8 00300 deny ip from 127.0.0.0/8 to any 65000 allow ip from any to any 65535 deny ip from any to any -Eric To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
