Their is one more question from site-to-site IPSEC VPN with Digital certificate ?
ASA1(config-ca-trustpoint)# fqdn ASA1.networklessons.local
And the attributes that identify our device:
ASA1(config-ca-trustpoint)# subject-name O=Networklessons, C=NL, EA=admin@networklessons.local, ST=North-Brabant, CN=ASA1.networklessons.local
The FDQN and Attributes name you chosen are predefined or we can give any attribute for any name ?
