no internet connection after vpn connection with at&t client
we've got a strange problem, a customer is using a seperated Port on the watchguard,
to connect to his VPN. If we are using this Port, which should only can use the internet and not the local network, with any other Computer, the Internet is working fine and we can also establish a VPN connection to another Watchguard (Mobile VPN with SSL).
The customer laptop is getting also an ip address of that watchguard, but if the VPN
connection is established via AT&T client to his Network, the connection is working
only for a short time. After that, the internet connection is lost and no other computer
can establish an internet connection, until I deactivate and reactive the Interface.
Are there any known issues?
Thanks for your help.
