Hello,
I have a Sophos Firewall XG330 (SFOS 19.0.0 GA-Build317), with many REDs distributed in different buildings. Each building has his own DHCP RED interface, but I've fixed some IPs. The problem is when someone with a static IP goes to another building (so a different LAN, but connected to the same UTM, when tunnel is up).
In this case, the user that has a static IP address on his phone or laptop, can't use the internet in the new DHCP RED interface, because his device keep the static IP of the previous LAN, where he's not anymore.
In the attached files, we have an example: some devices belong to a DHCP interface with LAN from 10.4.0.1 to 10.4.7.254. The IPs until 10.4.6.254 are reserved for the static IPs (image 1 and image 2) and the IP Range from 10.4.7.1 to 10.4.7.254 is destined for the dynamics IPs. Then, when a host of the first or second image (so one with a fixed IP between 10.4.0.1 and 10.4.6.254) has to go to another building (image 3), configured with another RED, and so another LAN (for example 192.168.84.101 - 192.168.84.200), he can't establish a connection, because his IP address remains 10.4.X.Y.
How can I resolve this?
Thanks for the help!
