Hello Support,

I am trying to configure a site to site VPN with ASA 5510, One ASA is behind a NAT device. Please find the setup

SITE A

LAN -----> ASA ------> NAT Router -----> Internet

SITE B

LAN -----> ASA ------> Internet.

Configured the site A as Orginate-Only and Site B as answer only. Am not able to estabish the tunnel as phase 2 is failing. Please find the error from both ASA's .I have enabled the NAT-T

Site A ASA Ipsec error log

Hi sreekumarpg, Please add your phase 2 config so i can take a look, if you are not interested on adding the config here, make sure the configuration is matching both side and the interesting traffic is mirrored. -JP-
