Hi everybody, i'm very new at ASA and firewall and i have trouble configuring an ASA 5506 for the first. I need to add the firewall in an existing network so i have decided to put the firewall in transparent mode. I can not have internet access from the inside network. I can ping 8.8.8.8 from the firewall.
My config : ISP Router(10.10.10.1) ---> ASA(10.10.10.254) ---> Internal Network(10.10.10.0).
: Serial Number: JAD214607JG
: Hardware: ASA5506, 4096 MB RAM, CPU Atom C2000 series 1250 MHz, 1 CPU (4 cores)
:
ASA Version 9.8(1)

I saw that it can be a NAT but not sure (nat (inside,outside) dynamic interface).
Thanks
