At home I use a Cisco WRT610N router.
I just recently installed a Dlink DIR130 at a client site. I enabled PPTP on the Dlink and configured some usernames etc...
I did a quick test while onsite and it appeared PPT was working internally.
I try from home and I cannot connect. It gets stuck on verifying username and password and eventually gives me an error 619.
I receive the same error from different machines at home.
After some researching I tried doing some testing with PPTPclnt.
I receive this error from my home machines...
WSAECONNRESET: connection reset by peer.
I can get into the DLINK via the web interace so I know the router is reachable on port 80 (I had enabled remote management previously)..
The customer site where the Dlink is has a T1 line from Cbeyond. I did contact them and they indicated there should be nothing blocking PPTP on their end, their router is also setup in bridge mode so all traffic is passed directly through to the Dlink which has the public IP address.
I am not sure if I need to make changes to my Cisco device or maybe the Dlink.
Any help would be greatly appreciated.
