comment nslookup resolves domains to IPs, but I can't get a response to pings to external servers
While all of the Windows workstations seem to be able to access the internet just fine (in spite of the inability to ping and trace route), the development server I started the thread about is a different story. It has all the same symptoms (inability to ping, etc.) but it can't access the outside world via browser, even though it can see, connect to and ping any internal machine and resolve external IPs. We're unable to ping any outside server. At this point I guess it's an issue with our ASA.

I was all set to say, "Psh, of course!" but as it turns out, no. It can access Google (and the rest of the internet) via browser seemingly unhindered, but it cannot ping Google (or any other external server). In fact, none of the machines on the local network can, but they can all access the internet via browser.

Hmm, I was able to confirm that the rules had been removed (running iptables -L -n returns a bunch of empty chains now), but even after restarting the network service and rebooting the machine (I also ran /sbin/chkconfig iptables off), I still can't ping external servers. I'm becoming increasingly aware that I'm in way over my head.

Running that command results in a long list of rules, with the pertinent one (I believe) being: REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited I assume that is the ICMP rule you were referring to. I guess I need to go learn how to modify iptables rules.

Hmm... I guess I'm in over my head. We're a really small web development shop without an IT guy, and our internal network was set up by a third party long ago. All I really know is that we have a router connected to a cable modem, and that connection is split among all of our machines (including the DC) via gigabit switches. # traceroute -n google.com traceroute: Warning: google.com has multiple addresses; using 74.125.67.103 traceroute to google.com (74.125.67.103), 30 hops max, 38 byte packets 1 * * * 2 * * *
