FreeBSD 6.0: Problem with network, doesn't use default gateway
Hi, this is my first message to the mailing-list. I hope that I have included enough information about the problem. The problem is that my FreeBSD 6.0 (release) won't use the default route (gateway). So I can't access anything on the internet. Hardware and network equipment: Dell latitude D810 (Pentium M 2.0 GHz, 1.5 GB of primary memory, broadcom gigabit/fast/normal ethernet controller). The broadcom chip uses the bge driver. I have looked in the man page for that and no troubles or something like that is mentioned. IPv4 address: 192.168.0.228 /25 The gateway is a netgear RP614 broadband router. IPv4: 192.168.0.199 /25 Also a windows 2003 server is acting as DNS-server for my network. FreeBSD shares the computer with windows XP pro SP2 using dual boot. In windows it works fine so this convince me that it's a software problem in FreeBSD. As said, it works perfectly fine inside the LAN, but not outside. I include a dmesg output (at the bottom) if that is of any importance and also output from ifconfig, netstat -nr, ping and traceroute. I was logged in as root while testing this. Notice that because I'm using an internal DNS-server I can do lookups. Obviously that wouldn't have been possible with the DNS-server provided by my ISP. alcoy# ifconfig bge0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500 options=1aTXCSUM,VLAN_MTU,VLAN_HWTAGGING inet6 fe80::214:22ff:fee1:41be%bge0 prefixlen 64 scopeid 0x1 inet 192.168.0.228 netmask 0xff80 broadcast 192.168.0.255 ether 00:14:22:e1:41:be media: Ethernet autoselect (100baseTX full-duplex ) status: active lo0: flags=8049UP,LOOPBACK,RUNNING,MULTICAST mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 inet 127.0.0.1 netmask 0xff00 alcoy# netstat -nr Routing tables Internet: DestinationGatewayFlagsRefs Use Netif Expire default192.168.0.199 UGS 0 52 bge0 127.0.0.1 127.0.0.1 UH 0 52lo0 192.168.0.128/25 link#1 UC 00 bge0 192.168.0.199 00:09:5b:10:de:14 UHLW2 190 bge0 1182 192.168.0.210 00:05:5d:0c:f8:23 UHLW1 29 bge0 Internet6: Destination Gateway Flags Netif Expire ::1 ::1 UH lo0 fe80::%bge0/64link#1 UC bge0 fe80::214:22ff:fee1:41be%bge0 00:14:22:e1:41:be UHL lo0 fe80::%lo0/64 fe80::1%lo0 U lo0 fe80::1%lo0 link#2 UHL lo0 ff01::/32 ::1 U lo0 ff02::%bge0/32link#1 UC bge0 ff02::%lo0/32 ::1 UC lo0 alcoy# traceroute ping.sunet.se traceroute to ping.sunet.se (130.242.80.31), 64 hops max, 40 byte packets 1 sentinel (192.168.0.199) 0.524 ms 0.518 ms 0.515 ms 2 * * * ^C alcoy# ping sentinel PING router.aqualize.tk (192.168.0.199): 56 data bytes 64 bytes from 192.168.0.199: icmp_seq=0 ttl=250 time=0.669 ms 64 bytes from 192.168.0.199: icmp_seq=1 ttl=250 time=0.679 ms 64 bytes from 192.168.0.199: icmp_seq=2 ttl=250 time=0.673 ms 64 bytes from 192.168.0.199: icmp_seq=3 ttl=250 time=0.673 ms ^C --- router.aqualize.tk ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.669/0.673/0.679/0.004 ms alcoy# Copyright (c) 1992-2005 The FreeBSD Project.

[snip] I may have snipped some clue to what's actually wrong, but don't let that discourage you from trying to file complete problem reports. I'm a snipper. What I found to be most relevant follows. Internet: DestinationGatewayFlagsRefs Use Netif Expire default192.168.0.199 UGS 0 52 bge0 [snip] This shows generally that the router IP is being properly used by FreeBSD as a gateway (Use = 52). Suggests that your assumption that FreeBSD isn't using the gateway properly is not correct. alcoy# traceroute ping.sunet.se traceroute to ping.sunet.se (130.242.80.31), 64 hops max, 40 byte packets 1 sentinel (192.168.0.199) 0.524 ms 0.518 ms 0.515 ms [snip] This shows the gateway IP is being properly used by FreeBSD as the appropriate route to ping.sunet.se. Indicates that the problem really is not FreeBSD's default route configuration or functionality. The route is clearly being used. alcoy# ping sentinel PING router.aqualize.tk (192.168.0.199): 56 data bytes 64 bytes from 192.168.0.199: icmp_seq=0 ttl=250 time=0.669 ms [snip] This shows you communicating with the gateway directly (confirms the assertion that local LAN operations are doing just fine). Since your packets are being routed and NATed by the gateway correctly when the box is in Windows mode, packets should be getting routed and NATed correctly for FreeBSD as well. That is, if the box in Windows mode is using the same IP number and mask as the FreeBSD settings (you should double check that it is). If the gateway is running fine (seems to be) and FreeBSD is properly using the gateway (seems to be), then the most likely suspect seems to be firewall configuration -- after your connection is properly routed, reply packets from the Internet could be getting dropped on the floor by your gateway or by FreeBSD. Have you configured any kind of packet filter (ipf, ipfw, other) for FreeBSD? Try disabling that and see if your results change. If so, tune your filtering rules accordingly. Use of tcpdump -i bge0 may also be informative (see man tcpdump). -- Greg Barniskis, Computer Systems Integrator South Central Library System (SCLS) Library Interchange Network (LINK) gregb at scls.lib.wi.us, (608) 266-6348 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I don't see anything obviously wrong with the configuration info you sent below. The problem you are having is more likely in the router you are using, but without that configuration info, it's impossible to tell. Are you using dhcp to assign IP addresses? If so, is the router doing that job or something else? Since you mentioned that it works when you boot into windows, are the network settings the same? (IP, netmask, default route ,etc) or is windows configured to use something different? How is NAT configured in the router?
