Re: RWW vs. VPN

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Once I put the server on the DMZ, it works fine...so I'll check the settings
you mention. I don't particularly want to have the server totally exposed on
the DMZ, so I would like to find the culprit. According to Qwest/Actiontec,
PPTP is setup already to allow up to 8 VPN sessions without making any
adjustments.

Thanks!
