Hello. We had 2 XG330 firewalls in our environment that failed within a week of each other. I was able to back up the configuration from the working firewall before it failed. We installed 2 new XGS3300 firewalls and restored the configuration to those. However, since doing that, we cannot get servers in our DMZ to connect to the other servers associated with them. We have checked all the firewall rules and NAT rules and they are the same as they were on the old firewall (our consulting firm was able to rebuild one of the old firewalls and compare the configurations between the new and old.) Our consultant seems to think that there could be an assemetric routing issue that could be related to the new v. 20 of the firmware? Has anyone else run into this? Can we roll back to the v. 19.5 to see if that will solve the problems? Thanks!
