Installing and Using OpenWrt
1

Dear all,

I have the following configuration:

INTERNET --- ROUTER --- OPENWRT AP REPEATER---

When I connect to my router, I can connect to my office VPN with Windows 10 computer and my iPhone.
When I connecet to the OPENWRT AP Repeater I can connect to my Office VPN with my iPhone but not with my Windows Computer.

Here you hace my configuration:
