I have a TP Link travel router with a (crappy) VPN client built in. I'm trying to connect to my FGT 80 via IPSec. (all my other VPNs work fine)

It looks like Phase 1 completes, but I cannot find any indication or idea why it doesn't complete Phase 2. I am currently using a guest subnet to connect.

My log is here: PasteBin

Hi,

What did you put as an IP for phase 2 all default 0.0.0.0/0 on both the end and also try to put subnets instead of named address at the FortiGate.

Perhaps I'm mistaken that Phase1 completed. I don't see any errors and the logs in the console say "IPsec SA installed"

I don't see anything in the logs which indicates why it's not completing.

Hi @username12341,

Can you please share phase 1 and phase 2 config?

Make sure that the Phase1 interface had localid-type set to auto instead of key-id’
This will ensure that the phase2 is successfully negotiated.
