Everything is the same as when running 1.6.5, upgraded to 1.8.0-rc1 and now can't get the set to initialize.

Steps to reproduce:

Start up 3 replset nodes.
Connect via shell.
Define the config and execute rs.initiate(config)

Keep getting error:

{
"startupStatus" : 4,
"info" : "myReplset",
"errmsg" : "all members and seeds must be reachable to initiate set",
"ok" : 0
}

rs.initiate()
with no params doesn't work either doesnt work either.
