Private destination address from Internet packets. Legetimate packet?

Posted on 2007-06-01 16:58:45-07 by tamadite

Once a while I can see I get packets from Internet with legitimate public source addresses but private destination address pointing to some of my LAN devices i.e. 192.168.112.32. Should I consider these sorts of packets as legitimate packets or should I create an entry in my firewall to block them?

Re: Private destination address from Internet packets. Legetimate packet?

These are legitimate packets. By using version 1.1 of HTTP the client is required to send a header field named "Host" which indicates the virtual host the request is aimed at. In the cases below, the client did not indicate it. This is described in RFC2616 section 14.23. These sorts of packets should not compromise the server.
