No Internet via VPN connection to SA520

After updating the firmware a couple weeks ago to 2.1.51, remote users now find that upon connecting to VPN they are unable to contact the Internet. To my knowledge this was never an issue before the firmware upgrade. I have tested and confirmed that DNS resolution does not seem to work after connecting the VPN tunnel, though I can ping through to, etc.

Does anyone have any suggestions for resolving this issue?

Thanks much,

No Internet via VPN connection to SA520

Hello Zac,

Under the VPN settings for IPSec, there should be an option for dynamic IP range. Under this option there is a check box for split tunnel support. Make sure that this option is enabled. One thing to note here is that if you have already configured the VPN tunnel, changing this option will not update the tunnel. You will have to delete the tunnel, select split tunneling and then recreate the VPN tunnel.

I hope this helps.
