Cannot go to company web sites after connecting through VPN with the new firmware R7900P — Nighthawk

I updated the firmware to the recent one Firmware Version
V1.4.1.64_1.3.25

After updating firmware, when I logged in my compnay network through VPN, I cannot go to any company intranet web sites and do any rempote login to thje servers. Any idea why I cannot do it. Before firmware update I did not have any issue. I disconnected router and connected my PC directly to cable modem, I did not have any issue going into servers, company intranet web pages. It seems that router is blocking some functions on VPN  or something else? When I enter the company through VPN, I can surf web pages but not intranet sites.

Any help and ideas are appreciated/
