Re: Ping/FTP to active IP address

["Jim Franz" <franz400@xxxxxxxxxxxx>]

What exactly is your gateway? a router?
If so, does it have both an "inside" and "outside" ip address? and your next
hop in the
route table must be the "inside" address.
Also, your router may have filter rules that are not allowing packets
originating from either your specific address, or generically so that all
your local traffic is not routed out.
since your ip's are public ip's, not private, is your whole network public
ip's?
