Setup: Toshiba 4005CDS FreeBSD-4.3-20010807-STABLE In my own defense concerning posting this here: I've posted this problem on `questions' `stable' and `net'. To date I have received no help whatever. Maybe since it is a laptop, someone here will take time to help. Summary of network setup: Local lan of 5 machines behind a hardware (NETGEAR FR314) Router/firewall. Machine 1 = Linux (Redhat 7.1) Machine 2 = Solaris 8 (intel) Machine 3 = win2k Machine 4 = Freebsd-4.3(snap) Toshiba laptop Machine 5 = win98 All machines on lan can communicate except the laptop. However, the laptop can connect to any lan or internet address with no problems. Seemingly this indicates the FreeBSD-4.3 machine has the ethernet interface and gateway setup well enough for outgoing connections and replies. The trouble comes when trying to connect to the FreeBSD machine from the lan. I can't ping, telnet, ftp, ssh to it. Telnet and ftp are temporarily enabled in /etc/inetd.conf. The Freebsd machine can ssh to other machines on the lan. None can ssh to it. sshd is running on the laptop. Possible pertinent kernel parameters compiled in: ======================================== options IPFIREWALL #firewall options IPFIREWALL_VERBOSE #print information about # dropped packets options IPFIREWALL_DEFAULT_TO_ACCEPT #allow everything by options IPDIVERT #divert sockets options TCPDEBUG Possible pertinent parts of /etc/rc.conf ======================================== firewall_enable="YES" # Set to YES to enable firewall functionality firewall_script="/etc/rc.firewall" # Which script to run to set up the firewall firewall_type="OPEN" # Firewall type (see /etc/rc.firewall) sshd_enable="YES" # Enable sshd sshd_program="/usr/local/sbin/sshd" # path to sshd sendmail_enable="NO" ======================================== cat /etc/rc.firewall 65535 allow ip from any to any ipfw list 65535 allow ip from any to any Renaming /etc/rc.firewall doesn't help either. Should the above lines mean all connections are allowed? If so, what the heck is blocking incoming connectons? I see nothing in dmesg or syslog output, that I recognize as pointing to a problem. One possible line is: IP packet filtering initialized, divert enabled, rule-based forwarding disabled. default to accept, unlimited logging What have I neglected to look at. Maybe netstat -nr, but it looks ok to my untrained eye. Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 192.168.0.1 UGSc 0 0 ed0 127.0.0.1 127.0.0.1 UH 0 0 lo0 192.168 link#3 UC 1 0 ed0 => 192.168.0.1 link#3 UHLW 1 0 ed0 => However ed0 ip address does not appear there.
