No Netowrk traffic after FMC and FTD upgrade from 7.0.4 to 7.2.5

[richard grant]

Hello,

We upgraded FTDs and FMC from 7.0.4 to 7.2.5 and are now able to route any internal network traffic. That said, we can ping the internet directly from the FTD CLI.

Your help is greatly appreciated.

Thanks

Is all the configuration in place on the FTD and is that configuration correct (NAT, routing, ACP rules, interface configuration, etc.)?

What troubleshooting steps have you already done?  You might want to reboot the FTD devices again just to be sure that there aren't any stuck processes causing the issue.  This will be the fastet way to solve your issue if it is not hardware or configuration related.

If a reboot does not solve your issue

• are the FTD interfaces line and protocol in up status?
• are you seeing any stale connection that might have been established  while the FTD was not completely finished booting?  (show conn)
• issue a packet-tracer to see where in the path through the firewall traffic is being dropped.
