No connection to third parties when connecting to F5 VPN edge client

Hi,

I am having VPN on Edge Gateway 8900 with HF 6, version 11x

I have about 5k plus users connecting to the VPN. We are using Full tunneling.

Everything was working fine until last week, where some group of Marketing users started complaining about not connecting to internet (external websites like gmail.com or yahoo.com) when connected to the F5 Big IP edge client adapter (which is installed on their systems).

Its not the problem with the adapter as i tried to uninstall and re-install it.

Most of my Marketing guys are on the fields and they work on MIFI wireless cards from Verizon.

They are able to connect to the internet when they are not connected to VPN using the MIFI wireless card. However, when they connect to VPN using F5 edge client adapter. Then the third party websites does not show up.

Please someone help me with this issue and give me some steps that i should follow or look into.

Truly appreciated!!!
