Asa fixed IP <> Asa Dynamic IP
Tunnel works fine if i configure with the vpn wizard,
I configure this ipsec-site2site on de HQ (fixed ip) as follow :
peer adress "emty" (couse the ip address is unknown)
connection name "vpn_s2s"
local and remote adress
and the psk
I configure this ipsec-site2site on de Branch Office (dynamic ip) as follow :
peer address "ip address hq"
connectionname "vpn_s2s"
local and remote adress
and the psk
by advanced :
ike negotiation mode agressivve
each time i see in de logging from the ASA on the HQ that the BO uses his external ip adress as a tunnel group id, the messages .....unknown tunnel group "external ip " appears,
Who can help me ?

Hi Adriaan,
Maybe you can post your configs here..Since I am not getting the information you put here...
Are you using name for the tunnel-group ?

Hi,
the log says :
4|Nov 14 2011|23:37:36|713255|||||IP = >>WAN_IP_ASA2<<, Received ISAKMP Aggressive Mode message 1 with unknown tunnel group name '>>WAN_IP_ASA2<<'.
it sending the WAN_IP_ASA2 as the name of tunnel-group
usually for dynamic ip address, we are using FQDN as tunnel group if we are using pre-shared key..
try for ASA1, change the tunnel-group to use tunnel-group
example :
if your domain is abc.com
then
tunnel-group ASA2.abc.com type ipsec-l2l
tunnel-group ASA2.abc.com ipsec-att
pre-shared
and in ASA2 try add command cry isa id hostname
HTH,
Vikram

Hi Vikram
i've changed the log, >>WAN_IP_ASA2<< = the external ip x.x.x.x
x.x.x.x. Received ISAKMP Aggressive Mode message 1 with unknown tunnel group name 'x.x.x.x'
11-15-2011 12:28 AM
Hi Adriaan,
I notice that...Okay, I have a question here :
ASA2 is using dynamic IP, that's why in ASA1 tunnel-group we can't use ASA2 ip address,..hence that's why I have advise to use FQDN...
The logg issue here is that ASA1 can not find the proper tunnel-group to land the connection...
other solution is to use rsa sig authentication
HTH,
Vikram
11-15-2011 12:03 PM
You're going about it all wrong. Instead of trying to identify the peer using a FQDN, you need to use the DefaultL2LGroup.
I understand that you are using 8.4 but the concepts are the same.
