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.

I have an older Cisco PIX 506 with two VPN connections. One links two offices (PIX-PIX VPN) together, another is for staff to access email & files. The file server on the local LAN the PIX is on are...


It could be a missing route... are the file server and email server on the same subnet? If they are then it is possibly not a routing issue.

Also it would be worth checking the tunneling settings for the VPNs... if you have specifed either only the fileserver subnet or specifically the file server address, then this could be the reason they can get to nothing else.

Hope that this has helped a little :)

How to connect my MSSQL server through VPN by using PPTP


192.168.1.X is a local ip address ,, i trust that thhe vpn is in seperate places and is done with the wan ip over an internet connection?????

OK maybe the problem isnt on your side but the main office building,, when connecting , have someone looked for repeated attemps to connect by observing the fire wall,, if it appears to be blocked byu the firewall simply diasable any and try it out.. If it works then all you need to do is set the firewall correctly..

I was reading the ip address in your original post and those are local address,s are you certin the VPN is correct ???? did you use the correct STATIC IP ADDRESS ASSIGNED BY YOUR ISP??

I am workiong from my home office but do not get throug to my firm ofice. I am connected with sonic wall global client, but when I try to ping the firm server but it doesnt answear.


It sounds like it might be an issue with the VPN client that is attempting to get to your server at the firm. If you are having issues, first contact the firm's IT department. If they still cannot get you connected then you will need to contact you ISP to make sure that they allow VPN connections.

Cannot connect to SonicWall VPN


My guess is that dhcp is using the same private network scheme. Try changing your home network scheme to something different than your office.
For example:
Office = 192.168.1.x
home = 192.168.2.x

If your cisco vpn client is behind the natted device then you need to allow nat traversal in the head office firewall and if you connect the vpn client through data card it will connect,

Can't connect to AT&T VPN


I'll need to know what router you're using, make and model, for more specific help, but sometimes there is an option for IPSec passthrough. For example, on my Linksys Wireless Router WRT54G, there is a set of buttons under Security/VPN that are entitled IPSec Passthrough, PPTP Passthrough, and L2TP Passthrough. Since I don't know what router you're using, I can't tell you wether or not your router supports such functions or not, but if it does, you need to enable them.
