How we can specify the source ip address in IPSec configuration? it means when we have multiple ip address on the interface and we want to use a secondary ip address as source ip address for specified peer in IPSec configuration.



I have this problem too.

You can specify the interface used as the source, but not an IP address. You can do this with the command:

crypto map local-address

Would it be possible to move the secondary address to a loopback interface? If so, you could use the command mentioned above to source the tunnel from the loopback address.

Hope this helps. If so, please rate the post.
