o.fulbert

Level 1

                   Hello,

               I use ton setup some ASA55xx but with the new version, i don't arrive to see some sample config on the CCO for help me to configure.

               8.2 or 8.3 config can't be upgraded to 8.6 ???

               I begin to read the CLI 8.6 config but ...... not very clear for me ....

               simple config with Dmz,web server and some static !!!!

               ASA 8.0 be so simple .... than 8.3 or up ....

               I don t see lot of people use 55x. Normal ?

Hi Bro

When you do an incremental upgrade from 8.2 --> 8.3 --> 8.4 --> 8.6, the configuration in the ASA will auto-convert for you. If it doesn't you could paste your 8.2 config, and we can assist you to convert it to 8.6 :-)

Warm regards,

Hi Fulbert,

Your config changes from 8.2 to 8.3 will have some issues in getting that converted especially with the NAT commands.

8.3 to 8.6 will not have any issues in the conversion. Most of the command set will be same

except few like NAT commands. The below sample of NAT will be helpful for you in distinguising between older OS and the newer OS.

Please do rate if the given information helps.

And what about this old command that permit inside to dmz without translation ?

static (inside,dmz) 192.168.0.0 192.168.0.0 netmask 255.255.0.0

?

object network Inside_subnet

network 192.168.0.0 255.255.255.0

nat (inside,dmz) source static Inside_subnet Inside_subnet
