VPN (PPtP) tunnel through D-Link DSA3200?

Hi there..

Long time lurker on this newsgroup, first time posting.

I've run into a problem that's stumping me. I have a D-Link DSA-3200
wifi portal device installed at my workplace. We've opened a second
location and I have a need to setup a VPN over the net. The problem
that I'm having is that I cannot for the life of me get the DSA-3200 to
pass TCP port 1723 to the VPN server. D-Link tech support has been
pretty worthless in helping me out with this, so I'm hoping someone
here has worked with one of these devices and can help me out.

Thanks,
Michael

Problems with TCP Port 1723 or GRE Protocol 47 traffic? Both are needed.
Some routers call the latter "PPTP Pass Through" or "VPN Pass Through".

You can run the test detailed in the "PPTP Ping" and "VPN Traffic" sections
on this page...

If the test fails the GRE Protocol 47 section your options may include...

1. Purchasing a router that is known to pass GRE Protocol 47 traffic
correctly
2. Purchase a VPN end-point type router
3. Use an alternative like OpenVPN

Hi Al..

Thanks for the link. I was unaware those tools existed. I'll play with
the PPtP tests and see what happens.

Thanks,
Michael
