or is this just stop working all the sudden after working condition for a while?

You can also post the 871 router configuration for further info.]]> http://www.dslreports.com/forum/remark,18958063 Mon, 27 Aug 2007 09:48:40 EDT http://www.dslreports.com/forum/remark,18954212 Pra3tor1an : I've configured a VPN server on my 871w using IPSec over UDP. I've done this using the SDM. When I try to open a connection using the latest client (5.0), I get these messages in the log:

Cisco Systems VPN Client Version 5.0.01.0600
Copyright (C) 1998-2007 Cisco Systems, Inc. All Rights Reserved.
Client Type(s): Windows, WinNT
Running on: 6.0.6000

Received malformed message or negotiation no longer active (message id: 0x00000000)

The only answers I can get so far from my research is that:

1) The group name/password are wrong, which I know is not possible.
2) I need to forward (UDP) ports 500 and 4500 on the 871w firewall.

If it's the port forwarding I need, how can I forward these ports for a network range, instead of just one static host IP? Thanks in advance.]]> http://www.dslreports.com/forum/remark,18954212 Sun, 26 Aug 2007 16:55:10 EDT
