ASA VPN IPSEC to TPLINK TL-R600VPN

Hello,

I am trying to connect a ipsec VPN from my ASA to my TPLINK TL-R600VPN

This is what I am getting from the TPLINK log.

Hi Michael,

It seems it’s failing on phase 2. Make sure all settings are the same on both ends…encryption protocol, strength, DH, key. Don’t forget the timers, that can be an issue. Also, adding a debug on the Cisco might give you more information to work with.
