It's not immediately apparent to me what the problem is; however I would
suggest hooking up Ethereal or tcpdump and taking a look at the traffic
coming back from the unreachable site(s).
Perhaps some TCP options are being set that are not being allowed
through your firewall for some reason. There must be _something_
different about the traffic and it should be fairly easy to find out
what it is.
