Management Servet NAT gateway

So , long story short we have a M270 and I backed up the config and implemented it into a newer M290 everything works fine except the SSL over TLS tunnels for our other boxes I checked EVERYTHING!! Nothing is working, if I plug the old box it pops right out , the new one is not connecting to the other boxes , what am I doing wrong here ? Thanks in advance .

  • Try rebooting your ISP device when you swap in the new firewall.
    It may have an ARP cache entry for an IP addr on the old firewall which causing failed incoming connections to secondary IP addrs.

  • The new one has the IP of the old one but yeh u are right maybe the MAC-Adress doesn’t change and it can’t initialize the connection . I will definitely try that tomorrow at work. Thanks
