Re: VPN connection not decrypting packets

on the remote vpn configured pix, verify whether the nat traversal has been enabled.

e.g.

isakmp nat traversal 20

Re: VPN connection not decrypting packets

I have added the line isakmp nat-traversal 20 and still not getting any decrypted packets on my end. I have attached a screen capture of the statistics window.

TIA
