hey! my situation: I have a 1 Meg Modem connection through my ISP in town. My freebsd 4.0 box is setup as a gateway with one network card handling the modem and another network card connecting to a five port hub. All PC's on the network have the freebsd box as gateway: 192.168.0.1 with my ISP's primary and secondary DNS servers listed as they should (all are Win98 boxes). They are also all assigned their own IP (192.168.0.2-4). What should their Subnet Mask be? The problem that I am experiencing is that web browsing/file downloading on the internally networked PC's is not working. For example, I am working on a Win98 PC (connected to the hub) and I type in a website address (www.yahoo.com) and goes as far as saying "Tranferring Data" and then things just hang... no network activity or anything. The same thing happens when I try to download files from FTP... I can ping/ICQ/telnet out to the outside network on any internal PC but I just can't get the web or ftp to work (when I need lots of data transferred)... I can reach my gateway PC (freebsd box) through ping and I can do a traceroute to any IP... internal or external The browser seems able to resolve to the IP of the website address. and even when I type in an IP of a website, the same thing happens. Any help or insight into this matter would be GREATLY appreciated. Here are the specs for the BSD box and the network: - FreeBSD 4.0-RELEASE - custom kernel - AMD Duron 600 w/ 64 megs of RAM - 2 NIC's Intel EtherExpress 10/100 AOpen AON-325 10/100Mbps - Alcatel 1 Meg Modem - LinkSys 5 Port 10Mbps hub w/ cat 5 cabling - all PC's on the internal subnet are win95/98 with the BSD box as gateway Specific lines from kernel: options NETGRAPH options NETGRAPH_PPPOE options NETGRAPH_SOCKET options IPFIREWALL # Firewall support options IPFIREWALL_DEFAULT_TO_ACCEPT options IPDIVERT # natd support FreeBSD box is acting as gateway, with the Intel NIC connected to the 1Meg Modem and the AOpen NIC on the internal subnet I have natd running with ipfw for the firewall... MY ipfw -a l --- 00100 0 0 divert 8668 ip from any to any via fxp0 65535 3102 717026 allow ip from any to any (I know this isn't a great firewall setup, I changed the rulesets for testing) My /etc/rc.conf: network_interfaces="fxp0 rl0 lo0" ifconfig_fxp0="inet 111.222.333.444 netmask 255.255.255.224" ifconfig_rl0="inet 192.168.0.1 netmask 255.255.0.0" hostname="blah.my.domain" ppp_enable="YES" ppp_mode="background" ppp_profile="pppoe" gateway_enable="YES" firewall_enable="YES" firewall_type="open" natd_enable="YES" natd_interface="fxp0" natd_flags="-f /etc/natd.conf" MY /etc/natd.conf interface fxp0 use_sockets yes same_ports yes Do I need to have a /etc/hosts file setup? And I suppose it should contain the list of all internal PCs with their allocated IPs? THANKS A MILLION!
