Hello all,
This is my first post here, I am happy I found it!
I have a VERY strange problem at home:
I am running 10.6.6 on a Macbook Pro
I am running 10.6.6 on an iMac
I am running iOs 4.3 on an iPad
I am running iOs 4.3 on an iPhone 4
My router/modem configuration is as follows:
Modem has LAN IP: 192.168.1.1
DHCP is enabled in the modem and has a range of 192.168.150 to 200
It is a Sitecom DC-227 v2 (for Analogue ADSL)
NAT is switched on and in "Special Applications" I opened port 1723 for TCP
Firewall is on
My Wifi Router is a Sitecom WL-351 v1
Its IP address is 192.168.1.2
NAT is off
Firewall is off
DHCP is off
DHCP works fine.
Internet works fine (websites, ftp, etc.)
Then.....I try to make a VPN connection to the office. It is a PPtP connection to Windows 2008 Server. I enter the server name which is: remote.xxxxxxxx.nl, I enter the user name and the password under Authentication settings. And I click connect.
So far so good, within in seconds I have my VPN connection and everything works fine. Then I disconnect the VPN and try to logon again after 1 minute or so.....and then it fails.
This happens on ALL my devices here, first time works, second time it doesn't.
I entered my modem configuration and reset the modem. After a couple of minutes it sometimes works it sometimes doesn't. Even after not trying it for 15 minutes or so and then giving it a retry it sometimes connects and sometimes doesn't. With my old modem I never had this problem.
At the server side the log file shows the following error:
A connection between the VPN server and the VPN client <my home IP address> has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47).
Does anyone has an idea what the cause of this problem could be?
Thanks!
Marco
