Works like it’s supposed to

Simple app does its job well

Great Security focused VPN

Been testing ASUS Instant Guard with my ZenWiFi BD4 setup and it’s been a pleasant surprise. Setup was straightforward, and it does exactly what it promises β€” securely tunnels my traffic back through my home ASUS router when I’m away, which gives me peace of mind on public Wi-Fi (or cellular) without paying for a separate VPN subscription. Combined with ASUS AiProtection and the included Trend Micro security features, it feels like strong value for a home network. N.B It’s not a replacement for a commercial VPN if you need privacy from your ISP or overseas exit points, but for everyday security and safe remote access it’s a very practical, cost-effective solution.

Auto connection still conflict

iOS auto connect function still conflict on the latest version

Ca’t connect after current iOS update

iOS auto connect function have problem on ios26. Turn on this settings will fail to connect VPN. Turn OFF auto connect could solve the problem. Please kindly fix it.

Issues with cellular data

When activated my cellular data was severely affected. The cellular connection . The phone kept showing full bars and calls could be made. It even said 5G but there was no internet. I troubleshooted with the phone company and they could not resolve it. I planned on taking the phone to Apple but decided to do a full reset first. After the reset, the issue persisted so I then checked the VPN settings. I found Instaguard’s VPN intermittently trying to connect. I decided to turn it completely off and to remove it and my internet worked again. I think that if I want to remotely manage my network, I’ll stick to port forwarding.
