Changing Flame ip address

Flame Flame Questions
1

Hi, I went and changed my routers ip address to a different subnet because I want to create 2 subnets, 1gig and 10gig, and Flame had a few issues loading. I went back a step and all is working again. In order to get the wiretap stuff to configure again after an ip change on the machine, is it enough to uninstall / reinstall flame or will I have to completely remove my Autodesk folder.

I think that’s because the system booted up with the previous IP. When the system is booting up and loading, the wiretap services are also setting up under the hood checking the network IP so if you change the IP later you must make sure network IP and Wiretap’s IP matches…an easy way to do that is just a reboot after the IP change.

macOS allows users to set the network service order in System Settings, which determines which interface is prioritized for outbound traffic. When two interfaces are assigned to different subnets, the system may route traffic through the higher-priority interface—even if that interface cannot reach the destination IP.

This can cause connectivity issues if the PostgreSQL server is only reachable via one of the interfaces. The problem isn’t with the subnets having “priority,” but rather with how macOS chooses which interface to use based on service order and routing rules.

Example Scenario

Let’s say you have:

  • Interface 1 (10Gb): IP 192.193.194.195/24
  • Interface 2 (1Gb): IP 192.191.190.189/24
  • PostgreSQL server: IP 192.191.190.200

If macOS prioritizes Interface 1, it will try to reach 192.191.190.200 through 192.193.194.195. But since that IP is on a different subnet (192.191.190.0/24), the traffic may not route correctly unless there’s a specific route defined.

John, as i somewhat understand routing tables instead of changing the routers IP keep the one it was and flame worked on and add a new subnet for 2nd NIC and subnet. then use static routes to get the two to talk to each other. Im going through something similar adding a 25gb network ontop of a 10gb one. Im close to solving the subnet routing but i havent lost my flame through the process as i kept the orig IP

Thanks, I solved the problem now by using 192.168.2.x as my 1 gig network and 192.168.1.x as my 10g network. The docs I read told me to not have any router/gateway info for the 10gig Nic and making sure the 1gig was above it in network prefs. II also uninstalled and reinstalled flame which also fixed the wiretap start issue I was also having.
