Hi,
I have a fedora38 server that's been updated to new versions many times over the
years. It seems now I'm having a problem with the static route I created many years
ago no longer being supported. I knew this was coming, but I'm unfamiliar with the new
methods. I'm using the old network-tools method, not NM or even nmcli.
It clearly doesn't understand my current config:

In /etc/sysconfig/network-scripts/ifcfg-enp0s31f6 I have the following (my domain
sanitized):
# cat ifcfg-enp0s31f6|grep -Ev '^$|^#'
HWADDR=4c:ed:fb:bb:47:93
BOOTPROTO=static
DEVICE=enp0s31f6
TYPE=Ethernet
ONBOOT=yes
IPADDR=68.195.11.45
GATEWAY=68.195.11.41
NETMASK=255.255.255.248
PREFIX=29
SEARCH="example.com"
DOMAIN="example.com"
DNS1=127.0.0.1

I'm also still using iptables, not firewalls or ipfw.
Ideas on how to "upgrade" my server would be greatly appreciated.
The first step you should do is to migrate the /etc/sysconfig/network-script to the
NetworkManager standard configuration in /etc/NetworkManager. The /etc/sysconfig-method
got deprecated some times ago and iwas withdrawn with F37 or so (don’t remember the exact
release, it feels like it was soooo long ago). The network guys provided a nice migration
tool which does all the work. Search the Fedora Magazine, there was an informative article
about the migration process. (Just found it:
https://fedoramagazine.org/converting-networkmanager-from-ifcfg-to-keyfiles/). The
migration tool migrates the static routes, too.
In case of difficulties, feel free to ask. Maybe on our Fedora Server mailing list.
