We have an SG210 that we use as a firewall for some of our servers, and we use the L2TP VPN. It meets our needs with a subscription and we've been very happy with the purchase.
Our L2TP VPN no longer works for iOS devices or Mac's with Big Sur.
I've seen the other threads detailing how to go to Remote Access -> IPsec -> L2TP-over-IPsec and remove "SHA2 256 (96 bit)" and add "SHA2 256".
The problem is if I try to go there it isn't allowed because we don't have a relevant subscription.
Is there another way to make that change? Like from the command line?
It doesn't make sense to have the L2TP VPN be usable without a subscription but not the settings that govern it's use.
Maybe a firmware update can move or copy the L2TP VPN settings like IPSec "authentication algorithm" to the Remote Access -> L2TP over IPsec page where they will still be accessible.
Thanks!
