On IOs (latest Version) I noticed the following:
- On 3G connection I can connect and everything is fine (internet and internal traffic (behind the VPN) through the tunnel)
- On WIFI I can connect and internet traffic is running through the tunnel, but internal traffic (behing the VPN) is not going through the tunnel. Same configuration is used.
On Windows 10 I noticed the following:
- I can connect but I can not access my fritz box router using fritz.box. I can access by using the IP. On a Windows 7 PC with the same configuration access using fritz.box is possible. Both PCs are using a separate internet connection compared to where the VPN NAS is located.
