Re: NIGHTMARE - AT&T Global Network Client + Linksys
I'm using AT&T IPSec Application version 5.09.2 and a BT 512kb broadband connection to VPN.
I'm not using an adsl router.
Using Win xp pro on both laptops.
When I VPN into the company network with the connected usb modem, all is fine.
Cannot use internet connection sharing on ibm laptop as that option is not available.
Instead it states:
"windows cannot display the properties of this coeection. The windows management instrumentation (WMI) might to corrupted..."
Great!!!
I connect the usb modem to another laptop (hp) and peform the internet share option for the modem, then I hookup the other laptop (ibm), the vpn fails.
The hp laptop is the gateway.
The ibm laptop is the vpn client.
I kept getting
"negotiating encryption keys with VPN server" "authenticating..."
then the VPN server ip adress would change and again.
"negotiating encryption keys with VPN server" "authenticating..."
Internet browsing is ok on both laptops.
Don't have the option to
"Check - Allow VPN to pass through a NAT device" as an option in the preferences tab.
I don't have a Net Firewall Service check box on the hp laptop network card but do on the ibm laptop.
Tried UNCheck - Negotiate UDP encapsulation with VPN tunnel server for NAT .... but no success.
There must be a way.
Thanks for any help. |

said by BaMoo:
I had to open udp ports 500 and 4500. BaMoo - thank you!! I had port 500 open, but opening UDP port 4500 also seemed to do the trick for me.
My config:
Time Warner Cable Modem
Linksys 802.11A+G Version 2 router, bought yesterday
model WRT55AG V2 firmware 1.10
Pre-Shared Key (PSK) security with AES encryption
My problem symptom:
I would see AT&T Net client 5.09.2 forever looping between
Accessing digital certificate --and-- Negotiating encryption keys
What I tried that didn't work:
Login Properties --> Preferences --> Click "Override..."
Unchecked: Negotiate UDP encapsulation with VPN server for Nat traversal
That worked for someone else, but didn't work for me. So I re-checked it.
Final list of all ports that I opened
udp port 500
udp port 4500
tcp port 389
tcp port 709
tcp port 5080
tcp port 50
The other list of ports that I'm supposed to open I got from the AT&T Help Desk. They claimed they weren't supposed to be giving me support, but I pleaded.
Question:
I opened the port by
1) @ the browser »192.168.1.1
2) "Applications & Gaming" ==> port range forwarding
3) Starting on the 6'th line down, started entering all the ports, used the IP of this laptop that I'm on now as the "to IP Address", and checked "Enabled" for each row.
Is this the right way to "open the port" ?
This seemed like the most logical place to do it.
Thanks again Bamoo !!

@198.57.x.x | Thanks!! I started having the same problem myself recently ("no response from IPSEC terminator") from my AT&T client. After opening the specified ports, it worked again. not sure why it started acting up in the first place.... |

This thread has been extremely helpful! I have found that the Net Firewall Service is the key to gettting onto the dialer - however, I have another issue.... once checked, I am now unable to print to my local printer which is connected USB to my host computer - using a Linksys wireless router to connect via a notebook to both the internet and to the printer. Can anyone suggest how I can connect both to the ATT dialer, and be able to print? It seems that the Net Firewall Service checkbox almost is acting like an on off switch to either being able to connect with the dialer, or being able to print locally. I want to be able to do both - or am I asking for too much:) |
