easy VPN on 1721

[ianwarb]

I am trying to configure easy VPN on a Cisco 1721 with a VPN module installed. When the router boots up i get the message :

*Mar 1 00:00:24.007: %CRYPTO-4-TRANSFORM_NOT_SUPPORTED:

Transform comp-lzs is not supported with the current hardware configuration

When i take the VPN module out it works. Is there any way to configure easy VPN with the harware module installed?

You'll have something like:

crypto ipsec transform-set myset esp-des comp-lzs

Remove the "comp-lzs" cause this is compression which is not supported by the hardware module. Compression can only be done in software which is why it works when you take the module out.

I don't have the command in the config you mentioned. The only config i have is for the easy VPN as follows:

crypto ipsec client ezvpn myvpn

connect auto

group group_name key shared_key

mode network-extension

peer

plus the two interface commands, inside and outside. I have tried to upgrade to an IOS that explicitly supports LZ software comp. with hardware, but am still getting the same error message upon boot up.
