VPN stablility problems

[Larry Smith]

Hi Cédric/Nick,

Thanks for the feedback. My network is actually as simple as they come. The 
problem exists even on two machines running on the same physical LAN (in my 
house). My router is set up to forward port 655 to one machine on that LAN, 
and to another port on a second machine. Even in that environment however 
the connection goes down sometimes. Both those machines are also connected 
to a remote machine which has the same issue but no more frequently than the 
machines in my house. I could try debugging things further as you suggested 
(Nick: I will look into all your suggestions - thanks), but since it's 
already the simplest set up possible, it should work out-of-the-box (and 
does normally except for this occasional instability). Since it's affecting 
three machines all running different versions of Windows (again, two in my 
house and one remotely), on the surface it seems unlikely to be a Windows 
problem (why would three different versions of the OS all have the same 
issue). It's therefore (likely) either a hardware issue or a "tinc" issue. 
My hardware is normally very stable however so I suspect it's a "tinc" issue 
(the most likely culprit at this point anyway). I'll try to debug it further 
to see if I can verify that but I wouldn't think it would (normally) be 
necessary to check or change any default settings for this to work (let 
alone any exotic settings).  Thanks again.

Regards,

Larry

I use Tinc since 4 years now, it links 11 sites at office and, in my context 
(Linux routers over MPLS networks), it works like a charm and is pretty 
stable.
Maybe you should try debugging harder the under layers of your network, or 
try a simplest configuration (LAN <=> LAN) and see if the issue remains.

Cheers
