Posting Forms via VPN fails

I was having a terrible time posting forms (or establishing IMAP connections) when connected to work via Cisco’s VPN client. I could not send mail via a webmail interface or run queries with phpMyAdmin but I could perform google searches. I’m still not quite sure of the exact cause, but I tracked it down to my wireless card (D-Link AirPlus DWL-520+ Wireless PCI Adapter). When I disabled the wireless adapter and enabled the wired interface, the problem went away.

I’m still at a loss for this and only mention it in case someone else is experiencing the same problem.I couldn’t find any reference to the problem online, so I hope this note helps someone else.

If you know why this is a problem, please drop me a note:

I would like to post the information here.
