That's consistent with (outbound request) packets being queued up waiting for "something" to happen. That "something" has happened by the time packet 14 is sent, all the requests get sent once it's happened, and so you see the replies to them with delays like that. I've seen it with things like dial-on-demand PPP and the like. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Shorewall-users mailing list Shorewall-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/shorewall-users
