One of my clients just switched to a setup where their internet connection is provided through a VPN router. Exactly why, I don't know.
Since then the client has experienced agonizingly sllloooooowww email performance. They are not happy. At all.
According to the sphincter that installed the VPN setup, it must be a problem with Dreamhost -- there couldn't possibly be a configuration or performance problem with anything he touched.
He's adamant about talking to a Dreamhost tech on the phone, and claims that will solve everything. (A phone call is also quite unlikely to ever happen, so I asked Mr. Snotty Tech to send me an email with his concerns, which he refused to do. DH does respond fairly quickly to emailed or written support issues, but I've never known them to actually accept or place a call.)
I'm rather fuzzy on VPNs, but as you can tell I'm getting sick of this tech guy, and it smells to me like he's trying to cover up his router misconfiguration by blaming the lowly discount web host.
Let's see...email was working fine, he changes some stuff, and now it doesn't work for him. Email still works fine for everyone else using the same email server. The client can happily look at web pages using their new connection. Sounds to me like the problem must be the stuff he changed, ya think?
I'd hazard a guess that the shiny new router is partially blocking or delaying internet traffic for ports 25 and 110. Shouldn't the VPN router separate out "internet" traffic from "VPN" traffic?
Anyway, does anyone have any idea what could cause this sort of problem? Is it remotely possible that something really is messed up at DH?
