Hi, Try the following 1) $ ping -c 5 google.com $ ping -c 5 8.8.8.8 see if you get a response 2) now try and initiate a connection manually $ telnet google.com 80 For troubleshooting, * Trying Disabling Iptables and see if that solves the problem $ /etc/rc.d/iptables stop also check if your routing table is configured correctly $ route -n And lastly, see if the network interface has been correctly assigned IP address, netmark and gateway $ ifconfig -a Hope this helps Regards, Gaurish Sharma www.gaurishsharma.com On Mon, May 31, 2010 at 1:29 PM, Vincent Van Houtte <vvh@xxxxxxxxxxxxx> wrote: > Hi group, > > Sorry to bother you (normally I don't intervene in this group and > restrict myself to the forums), but I'm in a pickle at the moment: > > I have a server set up to be everything for my soho: dovecot, nfs, > calendar, ldap, krb5 and also bind9 / iptables. > > Since I upgraded to a new server last friday, The clients on the network > have no connection to the outside world anymore.
