VPN Issues

[Dangerous]

Does anyone know of any issues why a VPN connection would be live for 60s then drop for another 60s and then return?

It doesnt fully drops the connection just times out to the server?

ISbox 6000 or something like that. Forgot to add this is only when connected via wired link into a router; GRPS connects fine.

Yep to the second.

60s fine
60s full packet loss
60s fine etc

Connecting via ADSL with eclipse (moved from AOL as they didnt support it)

Same issue with AOL though.

Sounds like a router/line issue. And i think you mean GPRS Ground penetrating radar system like all mobile phones use.



nope cos then it would do the same on GPRS too, and it doesn't. It could however be local DHCP. This is also required as VPN is useless without internet, would also tie in with the VPN not completely dropping as your probably getting the nea address within the VPN timeout period which is probably about 90 seconds.

aye 3G GPRS

The firewall is WatchGuard Firebox 700 that is managed by 3rd party but other users connect fine just this one user.

Well its a fixed box so I doubt it has anything MS on there.

PPTP I think

just learnt something.....

PPTP requires a Keep-alive packet to be sent... yea okay....

But at this microsoft site it says - EVERY 60 SECONDS default.

give google a search "pptp keep alive packet" - throws some info up about it all.

edit:
perhaps some are not being recieved or even sent and the server times out the connection before they are sent (and the client then silently reconnects?)

maybe changing this on the client could solve the problem? - or change the time before it drops out.

Thats for NT this is 2000 Pro SP4

But isn't 2000 pro/server/whatever built on NT... i think so.

Surely its worth a shot.

One of the register values isnt in there so guess not.
