Apple iOS 12 IP Sec and Cisco RV110W not playing nice

[crbris]

Hello,

I am experiencing an issue get a functional VPN connection (IKEv2 .. ProtonVPN) from my iOS 12.1 device (iPhone 7+) through my RV110W router. IPSec Passthrough is enabled. The connection works fine over cellular, and over a different WiFi connection. My service provider made a site visit today and established that he was able to get a successful connection through the router from his laptop. Their diagnosis is that there is an incompatibility between iOS 12 and the RV110W. They recommended that I ask you all for a possible configuration change to get them to play nice with one another. Anyone have an fix for this? I know Apple wrenched up some vpn things with iOS 12.. 

thanks -cb

Hello,

to start out with, why don't you use the Cisco AnyConnect App for IOS ?

Thank you for replying. I was unaware of the app, but it doesn’t seem to lend itself well toward ProtonVPN. Proton has its own app that allows for selecting any of its many servers based on load and location. I don’t believe it does anything different with the vpn configuration at the iOS level, but likely modifies configuration prior to each connection for the appropriate server. I’m guessing this since there is only one vpn configuration shown when I look in settings/general/vpn.
I’m hoping to be able to change a setting on n my router to allow the vpn connection to work like it does in all the other environments I’ve tried it in, which is basically independent of the router as long as IPSec is supported. Ideas?

Thanks -cb

When you try and connect through your ProtonVPN, how far do you actually get ? You might want to toggle between 'Aggressive' and 'Main' mode on the Cisco (page 104 of the attached user guide).

Can you post a screenshot of the IKE policy on your RV110W ?

According to the ProtonVPN app, I successfully connect (see screenshot). The problem is that I am unable to do anything. It behaves like a routing error or loop. Everything just spins and browser eventually says “server quit responding”. 

 In the router I do not have any IKEv2 policies. See screenshot..
