| NIGHTMARE - AT&T Global Network Client + Linksys
I am using Linksys' Wireless Broadband Router (Model No. BEFW11S4 Version 4). Internet connection is fine.
However, when I try to get on to my company's VPN using the AT&T Network Client (v5.05.1), it's not working.
This is a freaking NIGHTMARE. In the last two days, I have spent 4 hours + on the phone with Linksys. They have been very committed and helpful, but they don't have the answers. They are asking me to ask AT&T what the ports are that need to be opened in order for the two products to work together.
Worst part is that I had my VPN working on my prior (wired) Linksys Router (Model No. BEFSR41).
What gives? What do I do? Will this ever work? Is the port idea going to work? |

I have also have had issues with the ATT VPN client. Our company uses 5.04.3. The only routers that I have had sucsess with is the Netgear RP614, DG824m and the Zyxel B-2000. I have been through everything from fowarding almost every port to hosting a DMZ port. The issues I had is that you can log in to the VPN service but you then loose all tcpip services, then when you log out everything comes back. Then I have had where you log in to the VPN, I get the tcpip services but cannot see any netowrk drives or save attachments from outlook email. If you have the ability I would try another router if you have not done so all ready. The 2 netgears I would stay away from and have had issues with while trying to use the ATT client are the FM114P and the DG814. Hope this helps I understand the fustration..

I have been using ATT VPN client for almost 2 yrs now through Linksys routers with no issues, except once when I was using DLink 614+, but I unchecked "NAT traversal" in advanced options and shut of gaming server mode and it worked like a charm.
Download the latest version of ATT VPN Client.

Let me know if you need help configuring the options.

| HELP! i am having issues with linksys wireless and AT&T Network Client. I can connect to AT&T GNC without wireless, but wireless forget about it! What settings do I need to change. It worked fine until I had to replace my card. And I think I just don't have the right setting in place! Please, help! |

I am having the same problem with AT&T Net client. The problem started when I went to a Linksys WPC11 Ver 4 PCMCIA card, the version 3 card works fine so I don't think it is the ports. I connect directly to the network through a Linux server and the pereson that manages the server informed me the port were open. I received the same response from Linksys. But I have not contacted ATT&T yet. Linksys does know they have a problem with the Version 4 card but they do not have a fix. |

| I have a slightly more bizarre situation. I have a WAP11 router and my machine has a linksys wireless PC card. I can connect through AT&T vpn fine using the wireless connection to my router, but if I try and do it when directly connected to the router (no wireless card in machine) AT&T bombs out with a memory access problem.
Internet access is fine either way. |

Success! I had the same VPN wireless connect issues with Linksys WCP11 V4 wiress PC card and BEFW11S4 V4 router. Countless hours and I have it working! The trick is to install the new wireless card driver , contained in wpc11v4_061303.zip , and found at ftp.linksys.com/beta. Extract the zip file, do an "update driver" on the wireless card, pointing it to the new driver and voila! Even works with WEP enabled. Note, in the AT&T MTS client (5.05), in "Login properties" I also had to turn off "Negotiate UDP encapsulation with VPN tunnel server for NAT traversal" . The specific failure I had been getting is Error 118 (No response from IPSEC terminator during authentication). The beta code for the wireless card, and the AT&T client setting change, were both needed to get past the autentication error and get a good connection in wireless mode.

I have a linksys BEFWS11 version 3. I have a desktop (ethernet) and laptop (wireless) running through it fine. My husband brought his laptop home from work and I am having the same problems you describe here with his AT&T program (running ethernet into router). Problem is, I tried to upgrade his software (he is running 5.00.2195) it says connection timed out before it lets me download.
His AOL connection works, but when I try to us IE, it get the "cannot find server" error message. It's almost like he cannot access any secure sites as well as his AT&T software.
Linksys says to fix the secure site problem, adjust the "MTU" but I cannot get into the router setup (under filters) b/c when I try to get into the filter tab, it says since I have AOL, I cannot access that feature.
Help! Explanations in "layman terms" please! |

| Has anyone had any problems running AT&T Net Client over Virgin Broadband?
I've been using the VPN software fine at home - I have a BTOpenworld connection at home and use a BT-supplied (yawn!) Westell Wirespeed DSL MODEM.
However when I take the same labtop, modem and cable to a friends house, who uses Virgin Broadband, I have serious problems. AT&T Net client connects fine, and all appears well. However when I try to do anything on my corporate network nothing happens! No e-mail or browsing of Intranet sites.
I contacted Virgin Broadband but they "do not support business use" - helpful eh?
Is it a port problem? Is it a client software problem?
Help! |

I would say (guess) that either virgin are blocking the vpn protocol (so you can negotiate but not send data)
OR the virgin connection needs you to set a lower MTU... though I can't think why that would be... since it's ADSL I presume it's going over BT equipment anyway?
Try using ping to one of your intranet servers (by IP address).
If that doesn't get a response, i think you probably have the first problem. If short pings DO get a response then see you long you can make them before they stop (ping -l (that's a lower-case L).

| Short version: In WinXP I added key EnablePMTUDiscovery set to TRUE & rebooted based on:
»support.microsoft.com/?scid=kb;en-us;Q314053
which was pointed to by this guy:
»dev.remotenetworktechnology.com/···hole.htm
who has some good info on his other pages too. BTW, many of the other optional TCP registry keys were already set by some program (ATT NetClient suspected).
Detail:
OS: WinXP, with firewall ZoneLabs Integrity Desktop v3.5.175.057.
Private LAN connected to LinkSys WRT54G with FW level v1.30.7 Jul 8 2003, with TCP & UDP port forwarding of 500-500, 5080-5080, and 3389-3389. Also enabled VPN PassThrough IPSec & PPTP.
ATT Global Dialer: AT&T IPSec Application version 5.05.1
Before adding the EnablePMTUDiscovery key, Remote Desktop was giving me the black screen with cryptic message "connection to the remote computer was broken" after ATT VPN connections were complete. I also couldn't FTP files or network folder browse to all systems.
Note I keep hearing that ISP's are reconfiguring router network settings to limit virus activity, which may be adding to end-users network woes.
Hope this helps all you folks. Good luck! |
