L2TP/IPsec - Android to FVS336Gv3 - "the length of the isakmp header is too big"
I am using the guide I made to configure L2TP/IPsec on the FVS336Gv3: https://community.netgear.com/t5/VPN-Firewalls/FVS336Gv3-L2TP-IPsec-on-Windows-10/m-p/1063257#M4362 Windows clients are ...
I agree with you my friend there are many VPN which slow the speed of your smartphone so my suggestion is that use fast VPN like express or hma VPN.
thank you

Actually, dumping L2TP and using plain IPsec with the "NCP" VPN client app on my phone gets me ~23-25mbps of throughput, and so far works reasonably well; there are still issues with P1 reauth, as well as issues with handling IP changes on mobile LTE connections (that's something IKEv2 and MOBIKE would solve, but the Netgear doesn't support either). And a 3rd-part VPN provider isn't exactly what I'm looking for. It's actually the reason I got the Netgear.
Hi train_wreck,
Are you able to successfully get L2TP/IPSec to work between FVS336Gv3 and Android (specifically, any of Samsung Galaxy Note or S series) or iPhone?
I also use NCP VPN client on Android with IPSec VPN and the app works good. However, there's an associated cost. Would prefer to use the built-in L2TP/IPSec client that's in Samsung Android phone or iPhone. And thanks for the L2TP/IPSec cookbook instructions for Win10.
Nope, gave up on it. I have to think it's a problem with the Netgear, since the Android L2TP/IPsec works with every other VPN router device I've tired.
I have settled on using the built-in Galaxy S7's Android VPN client using "IPsec Xauth PSK", though have recently finally enabled certificate authentication, so am using "IPsec Xauth RSA". Using plain IPsec is actually better with the FVS336G, since with plain IPsec I have achieved ~25-30mbps of throughput to the phone/connecting device. L2TP is limited to ~5-10mbps, and is often slower than that.
