Well if it burns, thats probably a good thing. We just don't want to have anything to explode huh?  ::)

If Logmein works then you have a back door to the router in emergency cases.

Keep us posted.

You have to be using the ports actively before port scanning to get an accurate result i believe. Ports are not open all the time by default.

well i updated the local router

good thing i did... default configuration uses different IP range then I do and all my machines are static assigned

I lost all internet connectivity when i did that here as i am also static here

I am going to move one of my remote machines to DHCP  and MAYBE give it a shot

another dumb question

if i moved the VPN server into the DMZ   that would tell me if the DIR 655 is blocking or not right?

Yes, test the VPN server to the DMZ and test.

Damn, sorry about the explosion. I would recommend setting up one PC with a reserved IP address ON the router and install Teamviewer on this PC so you can get in the back door if something like this happens. I know it's too late now, however, for future needs.

Keep us posted.

trouble is that DLINK defaults to 192.168.X.X

I am mac os x/ Unix we tend to the 10.0.X.X

i allowed one to go with the DHCP bo luck

Might try teamviewer vs Logmein in the future

Ya, you'll need to set up one PC or something to make it so you can get in remotely when in emergencies I think. 10.#.#.#.# is a good working address pool however, ya, the default address for most Mfr routers uses the 192 pool. You might want to maybe set up one PC at the remote site that can be on a static IP address of 192 maybe and always one should something be needed in emergency. Maybe you might change back to 192 addressing. Got some things to figure out. Hope it works out for you.

OK at remote router,, I think the lost of access was a dns issue.... machines involved did not have an outside DNS address I will play with that later

OK loaded up the new firmware and no joy.   Still no LT2P/IPSEC  PPTP is fine
I might give OPENVPN a shot when I am bored

besides that I think i am going to give it a pass... I have always had issues with the DIR 655 and range  so thuis additional issue just adds reason to investigate alternatives

thanks for all the help though...I learned a lot

Something to review for DNS:

Good Luck.

Keep us posted if you get it going or find something else.

DLink has some new routers out. I recommend that you phone contact Sales and give them some details on what your network needs are and maybe they can recommend a good router for you.

Let us know if you find out anything.
