Hello, I recently got DSL in my home and want to allow other computers to share the connection. I cheerfully set up natd and an "open" firewall. I can get the FreeBSD/Gateway machine to use the DSL, no problem. The problem comes when I try to access the Internet from the other computers, it appears that the DNS lookup goes through just fine, but the computer is never able to receive any packets. Unless, and this is what is strange, I visit some place (using a web browser, telnet, etc) for a while, and then it seems that the other nodes can eventually go there. Sadly, this is not an optimum solution. As far as I can tell from the man pages and online resources (cheat sheets, BSD Today, archives), everything should be working fine. Am I missing anything? helpful info: dc0 is set up for outside world, fxp0 is the inside card, all the clients point to it for its gateway... /etc/rc.conf: ifconfig_dc0="inet 216.239.11.77 netmask 255.255.255.252" ifconfig_fxp0="inet 192.168.100.100 netmask 255.255.255.0" defaultrouter="216.239.11.76" gateway_enable="YES" natd_enable="YES" natd_interface="dc0" natd_flags="-f /etc/natd.conf" firewall_enable="YES" firewall_type="open" firewall_quiet="NO" /etc/natd.conf: use_sockets yes same_ports yes Kernel file: machine i386 cpu I586_CPU ident ARCHMAGE maxusers 48 makeoptions DEBUG=-g #Build kernel with gdb(1) debugsymbols options INET #InterNETworking options FFS #Berkeley Fast Filesystem options FFS_ROOT #FFS usable as root device [keep this!] options SOFTUPDATES #Enable FFS soft updates support options PROCFS #Process filesystem options COMPAT_43 #Compatible with BSD 4.3 [KEEP THIS!] options UCONSOLE #Allow users to grab the console options VISUAL_USERCONFIG #visual boot -c editor options KTRACE #ktrace(1) support options SYSVSHM #SYSV-style shared memory options SYSVMSG #SYSV-style message queues options SYSVSEM #SYSV-style semaphores options P1003_1B #Posix P1003_1B real-time extensions options _KPOSIX_PRIORITY_SCHEDULING options USER_LDT options IPFIREWALL options IPDIVERT device isa device pci # ATA and ATAPI devices device ata device atadisk # ATA disk drives device atapicd # ATAPI CDROM drives device atapifd # ATAPI floppy drives options ATA_STATIC_ID #Static device numbering # atkbdc0 controls both the keyboard and the PS/2 mouse device atkbdc0 at isa? port IO_KBD device atkbd0 at atkbdc? irq 1 flags 0x1 device psm0 at atkbdc? irq 12 device vga0 at isa? pseudo-device splash device sc0 at isa? flags 0x100 device npx0 at nexus? port IO_NPX irq 13 # Serial (COM) ports device sio0 at isa? port IO_COM1 flags 0x10 irq 4 device sio1 at isa? port IO_COM2 irq 3 device sio2 at isa? disable port IO_COM3 irq 5 device sio3 at isa? disable port IO_COM4 irq 9 # Parallel port device ppc0 at isa? irq 7 device ppbus # Parallel port bus (required) device lpt # Printer # PCI Ethernet NICs. device fxp # Intel EtherExpress PRO/100B (82557, 82558) device miibus device dc # Pseudo devices - the number indicates how many units to allocated. pseudo-device loop # Network loopback pseudo-device ether # Ethernet support pseudo-device tun # Packet tunnel. pseudo-device pty # Pseudo-ttys (telnet etc) pseudo-device bpf Any help is greatly appreciated, Trenton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
