[FX.php List] Using a web app over a VPN

[Dale Bengston]

Bob, this reminds me of three instances I've encountered years ago where Cisco routers were configured wrong to work with AFP on the Mac. Slowdowns, packet drops, disconnections. Things would work for a while and then go deaf.

Now, I know AFP on old Macs does not describe your scenario, but I'm going back to my original hypothesis that this is a problem with network hardware. I'd start with the firewall or other device where the VPN connects. As you point out, getting any real troubleshooting done is going to be difficult. You can always come back to what you know:

No VPN, same net, no problem. VPN, problem. Your code has not changed, so the problem is in the ether. Sooner or later, someone who owns the network path is going to have to own up to the problem. Until then, I'll be beaming positive thoughts towards Tennessee while you spin your wheels.

Not knowing FX.php of course, his brilliant conclusion was that "these lines of PHP code seem to be where the slowdown is." Four lines of code doing an FMView()... of COURSE that's where the slowdown occurs, because that's when it's trying to talk to FM Server!

I'm not sure what the problem was, but it had something to do with "packets being dropped" between the two machines.  Yeah, that's pretty vague, but it does sound like what could well be going on in your case.  Unfortunately, I have no means of getting additional details.  (I spoke with my client, who spoke to his contact, who spoke with the network guys...)
