des and 3des on same pix

careyg — Fri, 21 Feb 2020 05:46:59 GMT

I was wondering how I could create two vpn's from one pix to two others, one using des and the second using 3des. I have created multiple vpn's both using des so I know about the access-list for nat, the two isakmp keys and such. the thing I am not sure about is how to configure the isakmp policies...

Thanks

You need to add a few thing to get both working.

1) you will need a two policy statements

onefor des and 3des

isakmp policy 10 encryption des

isakmp policy 20 encryption 3des

2) You will need two ipsec transform-sets on for des and one for 3des

crypto ipsec transform-set 1 esp-des esp-md5-hmac

crypto ipsec transform-set 2 esp-3des esp-md5-hmac

3) Then on your crypto-map idenify which transform-set to use 1 or 2 -

crypto map vpn 10 set transform-set 1 (des site)

crypto map vpn 20 set transform-set 2 (3des site)

That should be all you need
