Hello Tom,

I have seen in other post that PPTP allow is the only Protokoll that i need. The problem is, i can establish the Tunnel but i can not send data trought the Tunnel. Is there a way to see wat is wrong in the Tunnel. When i Monitor the connection i see the Tunnel, but no other comunication.

Hi Jazzer,

On the remote VPN server, do you see the VPN connection in RRAS console?

Thanks!
Tom

Hello Tom,

I Think the Problem is not on the remote VPN server. We have many Mobile User and the Policy work's fine. Only with the Client behind isa2004B Server, we have problems. Must i have a spezial IP Range Defined in ISA2004 that give Access to the Remote Ip Range behind the VPN Remote Server?

Hi guys,

Here we go.

All the problem was a new faulty wireless router.

The VPN PPTP,L2TP and IPsec with the original bios does not work well.

I flashed, after a good talking with Linksys Tech Support, and finally is working verrry Gooood. [Big Grin]

Mr jazzer, please use the URL I posted last time, there is a document How to config "Roaming VPN clients" to allow access to your network, this will help you as it did with me.

Tom, short question.. [Confused]

Isa 2000, when you allow VPN inbound, outbound, the packet filters refers to PPTP Call and receive and protocol "47", when PPTP for ISA 2004 refers to 1723 how suppose to be. This a little confuse for newbies [Roll Eyes]

Anyway, thank you guys very much, and Jasser if you need help, I will be more than happy to collaborate with you on your configuration. Just let me know.

RJ

Hi Raul,

The PPTP protocol uses TCP 1723 for the control channel and GRE for routing. The definition uses the PPTP application filter, and the filter manages the GRE connection. Check the details of the protocol and you'll see the application filter is used in the defintion.

HTH,
Tom
