When using a VPN, there are two ways it can connect.

1. With a route enabled for just the remote VPN subnet.
2. With a default route set, sending ALL non local traffic down the VPN pipe.

I suspect you have this set up in the latter manner, and cannot get connectivity from the other end of the VPN. There should be an option on the VPN client, for windows, is is a checkbox labled "Use default gateway on remote network". I am unsure how this is phrased fol the SonicWALL Net extender.

Usually this occurs because you have not enabled Split Tunneling in the VPN settings. With Split Tunneling enabled you should be able to use your browser.

I assume you are using IPsec.

Hi JAtkins3,

Both Malmensa and John are correct. The behavior is caused by Tunnel All Mode being enabled in the SSL-VPN settings on the SonicWALL appliance. This cannot be changed from the NetExtender client. If the SonicWALL is running SonicOS 5.9 or 6.2, you can change the setting by taking the following steps:

1. Login to the SonicWALL
2. Expand the SSL-VPN menu
3. Go to the Client Settings page
4. Edit the Default Device Profile
5. In the pop-up that opens, go to the Client Routes tab
6. From the Tunnel All Mode dropdown, choose Disabled

I hope this helps.

Thank you all, I am trying to get access to the firewall now. Will keep you all in the loop. _Tyrant is correct there are no such settings in the netextender client to select a path for the internet on the local.

_Tyrant  does this lower the security on that sonicwall   by disabling Tunnel All Mode?

Hi JAtkins3,

No, this does not decrease the security effectiveness of the SonicWALL appliance. Disabling Tunnel All Mode simply allows your computer to access the Internet directly while the VPN tunnel is active.

Some organizations don't allow this because they treat your computer as though it were physically connected to the local network behind the security appliance when the VPN tunnel is active because the tunnel gives you a similar level of access to trusted and secured resources. Some security administrators want to filter your WAN access when the VPN tunnel is active to minimize the threat vector from the WAN.

If the SonicWALL appliance is configured correctly, every part of every packet will be scanned for threats regardless.
