My company has hosted it’s websites on ServerLogistics (PI HOST) for years, and mostly we’ve been satisfied with them. But over the past couple years, we’ve had a lot of pain and suffering because every single time our dynamic IP address changes, we no longer have FTPS access, and we must contact ServerLogistics to resolve the problem. Also, if we stop the FTPS connection quickly enough (before it makes multiple access attempts), we are still able to browse our websites and access via FTP without problem. But for whatever reason, if I use Freeway to upload via FTPS and try FTPS multiple times (or use Transmit to connect via FTPS multiple times and fail multiple times), we then will find that we can no longer access our websites, and even the FTP protocol won’t work.
To repeat, if our IP changes and if we try a single FTPS access, our FTPS access is blocked, but we can still access our websites and use the FTP protocol. But if we try a second FTPS access, then everything is blocked (no access to our websites and not FTP access). The only way to resolve the problem is to get our new IP whitelisted.
Having ServerLogistics whitelist our IP fixes the problem until the next time our IP changes, in cases where we access via FTPS. If we never access via FTPS (accessing only via FTP), we are never blocked. So what triggers this strange problem FTPS access. It’s totally bizarre to me.
Note that we are based in Japan and ServerLogistics is based in Southern California, if that matters.
I have repeatedly asked ServerLogistics to resolve this problem. But they have told me the following:
“So far is that as the system currently stands, there’s just no other way to do this that wouldn’t cause a major security flaw.”
I don’t understand why this cannot be fixed without causing a security flaw, hence my post here on FreewayTalk. Perhaps some of you who understand the ins and outs of web hosting, IP addresses, security filtering and the like can help me help ServerLogistics solve this silly problem once and for all.
And once again, please note that we are based in Japan, while our host is based in the US, if the difference in countries (IP addresses) makes a difference in this case.
I look forward to your thoughtful replies.
Thank you!
