I have looked through the NetPro forums for a couple of days now and have not found my answer.
My question is, how do I setup an IOS based IPSec VPN tunnel using a 2811 with IOS os SP Services 12.4(13)?
Let me know if you need any more information.
I was just looking at the feature navigator and it appears that the SP services IOS does not support Easy VPN. I would recommend using one of these feature sets:
Advanced IP Services
Advanced Enterprise Services
You can order this feature set upgrade through your Cisco partner.
