Upgrading from 8.4 to 9.1 issues (Transparent firewall)

xaeniac — Tue, 12 Mar 2019 01:16:52 GMT

Firewall is in transparent mode. At this time permit any any on trust to untrust and untrust to trust. It works great in 8.4; when I update the version to 9.1 it blocks all traffic yet nothing shows up in the monitoring mode. Downgrade to 8.4 and all is fine again. This is the simplest setup at this time and have it running in a lab. ICMP is blocked. All traffic is blocked and only occurs in 9.1

regards,

Sorry; You do not have the correct answer. This firewall is in a closed lab and not on the internet.

I did I write erase and rebooted on 9.1. I ensured the firewall was still in transparent, yet I did not see the bvi interface nor the option to create one.

configure terminal

int bvi1 ( is an unrecognized command in 9.02 and 9.11)

upgrading from 8.4 to 9.02 seems to hold the bvi interface.

I think we may have found a bug.

Any insights or can someone recreate this?

Hello,

That should not happen, is not that I do not trust you it's just that I have configure it and see it working

Log a session terminal on your favorite terminal app ( Putty, Secure CRT) and then show us the configuration , the mode is running,etc,etc

Regards

Ok we had to retype firewall transparent and then it took. It is pinging now on 9.0 2 but not 9.1; we had to wipe the device to get it to work as the upgrade was not good.
