I have been using the VPN Client 4.0.1 for several years and never had a problem until late last November 2006. Now, when I try to connect, it says:
1) Initializing the IPSec link...
2) Contacting the security gateway <IP>...
3) Authenticating user...
...and after a long delay...
4) Not connected.
This happens with all of my connections. So it appears to be client side versus server side. BTW, I think the server side is a 3000 Concentrator. I have Windows XP (Build 2600.xpsp.050622-1524 SP2). Windows firewall turned off.
I have attached the log file and the big problem seems to be PEER_DELETE-IKE_DELETE_NO_ERROR.
My ISP says these are the only ports that are blocked:
TCP 135 NetBIOS - MS Blast and Nachi Worms
UDP 137 NetBIOS - MS Blast and Nachi Worms
TCP 139 NetBIOS - MS Blast and Nachi Worms
UDP 445 SMB - MS Blast and Nachi Worms
TCP 445 SMB - MS Blast and Nachi Worms
UDP 1434 MSSQL - Slammer Worm
TCP 4444 Back Door - created by W32.Blaster.Worm
UDP 8998 SoBIG
UDP 2048 Cisco IOS Webcache (Vulnerability)
TCP 2002 Cisco Secure Access Control Server (Vulnerability)
TCP 4156 Back Door - created by Linux Slapper worm
TCP 5554 Sasser Worm
TCP 6777 BAGEL Worm
TCP 9996 Sasser Worm
I took my laptop into work and I was able to access some of my other VPNs with no problem. So, it only seems to be a problem at my home location :( My ISP insists that they are not blocking anything other than the above.
Do you think 4.8.x client will help? To me, it still seems like a problem with my ISP. Also, where can I get the 4.8.x client - you have to be special registered or something to get access to the download.
Had gone to a dual monitor setup at home. The (explicit word deleted) login window was somewhere off the screen and I could never see it. When I took my laptop into work, it was a single display, so I could see the login window there.
