Connectivity Issues after upgrading to R80.30 from R77.30

[ziggurat]

Guys, hope you can help.

We've upgraded from R77.30 to R80.30 this morning but ever since, we've no connectivity. The gateway connects but there is no ocnnectivity to network resources

Can anyone spot anything suspicious in these log files?

I've also attached a pic of the status, which shows no packets being sent even though it's connected.

Thoughts would be very much appreciated.

Thanks

First, have you done a policy installation from the management since upgrading?
Second, If you look at the routing table on the client when connected, do you see routes for the remote networks reflected there?

Thanks PhoneBoy. Looks like this was caused by a MEP setting in R80 version. Thanks for taking the time to reply.

im doing another one tomorrow. I’m slightly more worried as this Checkpoint has 10 IPSec tunnels terminating into it. The devices on the other end are Checkpoiny UTM-130 devices running R77.10

Updgrading the core to R80.30 won’t prevent these tunnels from establishing will it?
