Posted: Mon Mar 31, 2008 12:19 am Post subject: WM6 PPTP VPN
I have an Samsung SGH-i780 with WM6Professional and trying to reach my corporate imap email server (cyrus imap) through a PPTP VPN with unpredictable results.
I've been able to reach the imap server a few times. If i work through my home wireless lan everything is working smoothly.
I've been able to connect even through GPRS some times but only with a "fresh" configuration (hard reset). As soon as I connect through the wireless lan the device seems to learn that the VPN is reachable only through when a wireless lan is available. The device tries to connect to GPRS but immediatly after I have a VPN error message.
The only solution was an hard reset ... but even this solution is not working anymore.
Any advice? A colleague with WM5 has no problem at all ...
The IP address of the imap server is the same in both cases (wifi and gprs) and also the vpn server is the same (it has a public ip).
The imap server is configured with his own FQDN.
Anyway I find out that sometime rebooting the device helps. As I said previously seems that the device "learns" that the vpn server is reachable via wlan and forgot the existence of GPRS if wlan is switched off ... rebooting seems to fix the problem ... but really I'd like not to reboot everytime I walk nearby an open spot at the airport ...
The situation you describe (caching different IPs) is not possible since the hostname of the imap server exists only on the internal-private dns servers and only has one private IP.
Regarding PPTP I setup a Linux based server using a completly different range of IPs but this doesn't seem to be the problem since I can browse internal-private web sites with no problem at all.
Again: I solved the problem rebooting the device that is wired from my point of view. Based on my experience that means WM6 cache the "best NIC" to reach the vpn server and when it cannot find it anymore (wlan is turned off) instead of trying with the other devices (GPRS) it just give up ...

This is my first post on this forum and I want to say hi to everybody.
My issue is somehow similar with the subject discussed in this topic therefore I did not want to open a new thread: I want to connect to my Company's VPN and read my e-mails.
My Company uses a Nortel Contivity switch to which I successfully connected with Bluefire Mobile Security VPN v2.7.5, Build 706 (IKE=DES+MD5+DH1; IPsec=3DES+MD5+LZH+PFS; NAT traversal active), using a cellular HSDPA connection. Now comes the bad part: I cannot configure Outlook to use the Exchange server nor the IMAP or POP servers (I tried with Flexmail 4 but with the same results) - it always say that the servers are not accessible. As far as I could figure it out, it seems that after the tunneling is operational, Outlook or any other software still tries to access the internet through the cellular connection (I tried to traceroot some addresses and it ALWAYS goes through the cellular line (not the tunneled connection).
What would be the correct settings in my connection manager so I could access the my Company's Exchange / POP / IMAP servers after I setup the VPN manually with Bluefire?
