Model: ER605 (TL-R605)

Hardware Version: V2

Firmware Version: 2.1.2

Hi All !

I'm using two ER605 to setup a S2S (LAN to LAN) VPN between my Home and my Weekend House.

(I have no OC200 or OC300 controller which is used in most of the Youtube videos)

The weekend house is the L2TP Client setup as Ipsec Encrypted and Home is he L2TP server.

It's a simple setup I've just setup the L2TP server and client, chosen Encrypted and it's working nicely.

However I can see that this default encryption method is only SHA-1 AES-128.

What would be the right steps to setup a more strongly encrpypted Ipsec in the tunnel ?

I'd expected to setup an Ipsec Policy and then choose it to be used at the L2TP but either I don't understand the logic or I' doing something wrong, but it's not clear.

Any help is appreciated, thanks in advance.

@MonsterVic

Sorry but as I know you won't be able to choose the encryption method if you choose L2TP over IPsec, if you wanna use some other encryption, just use IPsec then.

Is there no wait to change this in the CLI? IDK why TP link cannot allow us to manully config the IPSec tunnel

https://www.tp-link.com/us/support/faq/3842/

If we want to use the VPN server as a proxy gateway we stuck using ikev1 and sha1? why does this auto config to such a weak algo?

I don't have exact measures availiable for yoo right now, but it's enough to constanlty transfer 2x4k camera video, plus opposite direction to watch 1080p Movies remote...as far as I rememeber when I did the measures it has hit the 100Mbit rate. (Line is 1 Gbit). So it was good enough for my needs, and definitely faster and more secure than the oldschool VPN formats.
