Hi there.
I have recently upgraded a 12.3.11T 837 router to 12.4.4. Everything is working - apart from one thing.
It would seem that the ESP support for NAT is not working correctly - or I need to do something else.
in the NAT debug I am seeing:
*Jul 3 14:02:48: NAT: IPSec: cannot find In->Out ESP conn, OG=xx.xxxx.xxxx.169 IG=xx,xx,xx.189 SPI 0x268DEB97
I am guessing that OG = Outside Gateway, and IG = Inside gateway as this corresponds to the IP address's.
Rolling back the IOS - it works fine again.
Does anyone know of anything that I can do / any Ideas? I have tried the SPI matching nat service option but this does not seem to make any differance either.
Any help would be much appriciated.
Kind regards
Jon Paterson
