Port 80 requests just seem to hang whether done via a dns lookup or using the ip address. Checking the logs seems to indicate that no requests now arrive, but that we have seen some external requests since the ISP changed. The https/sshd/mysql etc servers are still visible externally and the http server is visible on its local address and if you visit the external address from inside the network. I suspect that either I've still got some misconfiguration on the server, gateway or or dns(although this seems less likely). Alternatively the ISP might have some other block in place. I've looked for the old IP address in /etc and found no usages the gateway appears to be correctly set up. What tests can I do internally/externally to see what happens to my port 80 packets? -- Robin Becker
