If not then post rc.conf also. Give interface name of Nic card connected to public internet. Has this network ever functioned correctly or is it something you are just putting together now? -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of Dave Raven Sent: Thursday, June 24, 2004 5:29 PM To: freebsd-questions@freebsd.org Subject: RE: Urgent 4.9 networking problems I have made further progress - thanks for all your steady replies. I know it might look like I haven't looked into it enough but this is just part of my bigger problem - here we go.. By adding my routers ip and my local machines ip to hosts, I've fixed the telnet to the router and the ping -R - but why is telnet timing out ?? I have NO DNS at all - there is nothing in resolv.conf yet it still makes requests to local host. I have to disable dns. I have no idea why it would sit for 2 minutes trying to resolve the ip for my telnet though??? Is this a problem? How do I stop dns altogether... The machine is acting as a firewall with NAT'ing and routing. The real problem that's gotten me down to here is with IPNat though - it says its map'd the address but in actual fact freebsd forwards it. Could this all be a red herring as a dns problem?

Ping ip address does no DNS lookups. Ping freebsd.org will not work either. With out a lot more detail about your network environment, the best I can say is look at how your network resolves DNS lookups. Some times a ISP will change the ip address of their DNS or DHCP servers and if you have their ip address hard coded in your firewall rules your network will just stop talking to the public internet. Start your research there. -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of Dave Raven Sent: Thursday, June 24, 2004 4:54 PM To: freebsd-questions@freebsd.org Subject: Urgent 4.9 networking problems Hi all, I really need some urgent help with this I'm completely confused. I have a FreeBSD 4.9 machine running ipfilter ipnat vrrp and a few other services, today is the first time I tried to access through the specific method but now every interface and every local address I try has the same problem. I can ping anything - but any other kind of traffic waits for about 2 minutes before transmitting - this is true with tcp and udp. I'm trying to access machines on the same network - and if I ping -R you can see the same effect - pasted below. I've also included the interface that I'm trying to do this on although it seems to be happening on all my other interfaces.. I try to telnet to a cisco router that's on a switch I'm plugged in and I see the same behaviour - it just waits then suddenly responds very quickly. My IpFilter rules don't log anything until it responds at which time they pass it - and tethereal + tcpdump also see if perfectly AFTER the long delay. It appears that its sitting on the kernel for 2 minutes??? It just does NOTHING then all of a sudden responds. The only thing I can find that works is icmp - and perfectly. I'm sorry for the urgency but its very high priority Thanks in advance Dave # ifconfig fxp1 fxp1: flags=8843 mtu 1500 inet x.y.186.3 netmask 0xffffff00 broadcast x.y.186.255 inet x.y.186.1 netmask 0xffffffff broadcast x.y.186.1 inet x.y.186.15 netmask 0xffffffff broadcast x.y.186.15 inet x.y.186.14 netmask 0xffffffff broadcast x.y.186.14 inet x.y.186.142 netmask 0xffffffff broadcast x.y.186.142 inet x.y.186.33 netmask 0xffffffff broadcast x.y.186.33 inet x.y.186.124 netmask 0xffffffff broadcast x.y.186.124 inet x.y.186.250 netmask 0xffffffff broadcast x.y.186.250 inet x.y.186.122 netmask 0xffffffff broadcast x.y.186.122 inet x.y.186.25 netmask 0xffffffff broadcast x.y.186.25 inet x.y.186.127 netmask 0xffffffff broadcast x.y.186.127 # date ; ping -R -c1 x.y.186.253 ; date Thu Jun 24 22:43:13 SAST 2004 PING x.y.186.253 (152.110.186.253): 56 data bytes 64 bytes from x.y.186.253: icmp_seq=0 ttl=255 time=0.414 ms RR: x.y.186.253 x.y.186.253 x.y.186.3 --- x.y.186.253 ping statistics --- 1 packets transmitted, 1 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.414/0.414/0.414/0.000 ms Thu Jun 24 22:46:58 SAST 2004 _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
