i'm just quite wondering how come your dhcp-server attempt is successful. class-map inspection_default match default-inspection-traffic ! ! The responder may use it to match the local tunnel-group and pre-shared key if needed. TY - may I ask, how you got this test output?
The group-policy attributes is setup with the dhcp-network-scope (the same as the scope address on the dhcp server). The following line reaffirms that the obtaining of IP address is indeed! In ASA firewall, the following default commands enable tunnel-group name lookup based on the OU (first) than IKE-ID (if present) and finally the Peer IP address: tunnel-group-map enable ou tunnel-group-map enable If you do not define a network scope, the DHCP server assigns IP addresses in the order of the address pools configured.
Every entry in this map matches either part of issuer or subject DN in the certificate. Join Now For immediate help use Live now!
