Can't connect to AT&T VPN

Hi,

I'm trying to connect to my office VPN using "AT&T Global Network Client" and I'm getting below error:
The connection timed out waiting for the VPN server to respond. This can occur if your computer is behind a firewall that does not permit UDP or IPSec traffic. Contact your local network administrator for assistance. (229)

I'm connecting my Laptop to the Router which is connected to the comcast cable modem. When I connect my laptop directly to the cable modem I am able to get the VPN connection, so, obviously my Router is blocking some traffic.

I've tried opening up all kinds of ports and protocols but it just won't work.

I would really appreciate if any one can shed some light on this for me.
I am having a similar problem

The VPN connects thru LAN cable but not thru wireless. At the same time all the websites connect thru cable and wireless equally well.

I use AT&T VPN client . My router is comstar Wireless N router .
Please let me know if there is any thing I can do .

Thanks,

Bobby

As you told me that all the ports are open so in that case you can get in touch with your ISP and ask them to enable IPPASSTHROUGH on your office laptop.

What is the best modem to connect to the internet via VPN?

If you want to change settings on the one that you have because of the protocols for assignment of addresses let me know

Need to hard reset my WAG200G to connect to VPN


You will see a reset button at back of your router so all you need is to keep holding it for 10 seconds then unplug the power jack for like 1 min and then your device shall be reset.

I am unable to connect to my VPN, although my wireless connection is excellent


Double check that you are using the proper WEP key and VPN settings. You can also try using a different channel for your wireless. Many of these systems use Channel 6 as the default channel. Change this to channel 10 in the router. If you are forcing 105mbs you will need to change that to automatic to make this change as in forced 105 mode the only broadcast channel to use if 6.

Unable to connect VPN using Arris Modem & Comcast Router


hi, mate check firewall settings of your modem/router. Then contact your IT administrator and he should be able to make changes to configurations for you. In most cases if server classify's your connection as unsafe it rejects it.

Cannot connect to Remote Desktop at Work From Home


there is a ver 5.06 of the client out by now, it is even win7 compatible, perhaps try upgrading to that version.

yes, there have been issues reported with early 5.0x and he was correct to test an older stable version.
The VPN tunnels work the same way with either version, therefore I would rule out your modem to be an issue.

Network cable unpluged error sign


Hi .

With most issues like this it has something to do with the ethernet cable or modem. If you tried replacing it and stillhave the same issue then it could be on your PC.

You can check device manager first by going through the steps below:

Assuming you are using winxp { almost same steps for vista}:

Start > control panel { classic view} > systems > hardware > device manager and on that window pane look for the +network adapters > make sure your devices ion there doesnt have red X on it . If so right click it and choose Enable. If it has a yellow or red exclamation marks { IRQ conflicts} then you need to reinstall the device by right clicking it and unistall > restart PC and make sure you have your system disk for your PC.

You can also check your network connections by going to start > run > type : ncpa.cpl on the run command and it will route you to networlk connections .Check if your network connection is disabled. , ifYES right click and choose Enable.

If that doesnt hel assuming you have replaced ethernet cable/ modem then might as well buy a new NIC {network interface card} for your PC to isolate the issue.

Other works around for this is using a USB connection to your modem or getting a wireless USB for you computer and get a router instead for wireless conenctivity.

In this way you mayu connect multiple computers in the future and wont have messy cables running throughout your house.

Cheers.Hope this helps.

Let us know soon.

Good luck

Hi,
Please see the specicification, also check with you company
IT Admin, to release it to the Max speed or to check the
net work cable, may be too long, also Test the cable with a Data Test meter and conform the data quality. Or change the port from main router.
Otherwise change the whole networking router.
