Topic: VPN PPTP using SME5.6UR

[Hervé]

Hi everybody,

I have some problems trying to use PPTP with a fresh installed 5.6UR (Unsup. Rel. ).

First of all, it seems very important to indicate that the problem doesn't appear using SME 5.5, with exactly the same hardware, onto the same environment.

Situation :

Station A --- SME 5.5 --- ADSL ......... ADSL --- SME 5.6 --- Station B

If I try to make a PPTP link from Station A to SME 5.6 Network XOR a PPTP link
from station B to SME 5.5 Network, the connection starts, but many packets GRE are lost or bad ordered :

pptpd[26713]: CTRL: Received PPTP Control Message (type: 5)
Jan 12 15:08:09 gw01 pptpd[26713]: CTRL: Made a ECHO RPLY packet

As a result, the link is very unstable.

If somebody have an idea of what's going wrong ... I would greatly appreciate !.

Kind regards,

Hervé ( Ps : Sorry for my english, french speaking ! )

Exactly the same problem.

I know my reply to be not helpful, but this confirms the issue.

Rgds,

I have a similar, perhaps related problem.

Outgoing PPTP connections through the gateway (from both Linux and Win2k) no longer work after installing 5.6UR.

I ranted thus:
 
> Outgoing PPTP connections through the gateway (from both
> Linux and Win2k) no longer work after installing 5.6UR.

Of course, as soon as I posted this I found the problem - I needed to have 1 pptp client specified in the "Remote access" panel.

Sorry for the false alarm
