I have two WR21 and try to setup a IPSec VPN tunnel.
The log of responder will shows the message as following repeatedly:
13:57:52, 09 Mar 2021,(96) IKE SA Removed. Peer: WR21_TEST,Negotiation Failure

There is no New Phase 2 IKE Session but only Phase 1.
The configuration of two WR21 are match for each other.
I have set up a successful IPSec tunnel before I sent one WR21 to other country.
Maybe the problem is from the ISP of other country...
Any idea will be appreciated!
