Before the restart, the Traefik ingress external IP was reachable from the Linux host machine and the LAN (192.168.1.0/24).
Now, after the restart, the IP is 192.168.5.15, which doesn't match any IP route on the host machine.
❯ ip route get 192.168.5.15
192.168.5.15 via 192.168.1.254 dev wlp3s0 src 192.168.1.149 uid 1000
I have Rancher Desktop Version 1.8.0 on Ubuntu Linux 22.04.
I believe the problem was that I rebooted after following the Rancher Desktop instructions for Linux, which do not hint that it's necessary to persist the unprivileged ports exception in sysctl.conf. I've sent a PR to add a hint.
