We using the UTM on a public IP-address block of 4 adresses.
This IP-addresses are assinged to 1 interface (I call it interface1 for now) 1 address isthe default interface address and the others are addtional adresses.
This interfaces also contains the default gateway.
In the definitions the intern IPv4 entry is connected to this interface.
In the nat maskerade rules is the default ip-address of the interface defined as maskerade address.
Our ISP informed use the ipadresses are going to change. The new adresses are assinged to the connection already.
Tha change must be done before april 30, when the "old' addresses will be disabled.
For the change I create a new interface (I call it interface2 for now) with the new Ip-addresses. (1 interface address and the others as additional)
as soon as I defined the default gateway to this interface the UTM notifited my that there may not been multiply default gateways been defined and the config will automaticly enable uplink balancing.
After this everything worked fine.
My tought was maybe to easy.
Disabling interface1 must do the final step.
Unfortunly, it impossible to disable or remove an interface whice is part of the upload balancing.
So I removed the default gateway from interface1, the upload balancing is disabled now and all settings (maskarade address and internet IPv4 definition are set to interface2
However, I'm unable to connect to the internet right now.
When I return the default gateway to interface1 everything sames to work again.
Can somebody tell me what's wrong in my config?
