Hello fellow techies. My company recently upgraded to a VPN Client remote network from a token ring network that they used to use, and I can only access the network via my ethernet connection straight into my cable modem.
When I try to access the network via wireless over my Linksys Router I get the following error message.
Initializing the connection...
Initiating TCP to 220.127.116.11, port 10000...
Failed to establish a TCP connection.
This is odd, because if I am in a hotel with a wifi hot spot, I can use my wireless connection all day. Any solutions...
Please let me know if you need additional information to diagnose since I've tried everything a novice could...
Re: Cannot access VPN Client over Wireless Network
The reply from the VPN Concentrator is not getting to the Client, and the Client is retransmitting the connection request. The problem is usually an Access Control List (ACL) or routing issue.
Verify that the Internet Security Association and Key Management Protocol (ISAKMP) port -- User Datagram Protocol (UDP) 500 -- is not blocked by an ACL, and verify that routing to the workstation from the VPN Concentrator is correct.
If you are using IP Security (IPSec) over UDP or IPSEC over Transport Control Protocol (TCP), make sure those settings have been turned on for both the Client and Concentrator.
You can configure the Concentrator to use IPSec over UDP and IPSec over TCP at the same time. The VPN Client can use either one, but only one at a time. It must manually select which one it is going to use.
To configure IPSec over TCP, select Configuration > System > Tunneling Protocols > IPSec > NAT Transparency. Make sure that IPSec over TCP option is checked.
To configure IPSec over UDP, select Configuration > User Management > Groups > Group Name > Client Config. Make sure that IPSec over UDP option is checked.
