Found another web page that says I should turn off stp: https://bbs.archlinux.org/viewtopic.php?id=207379 The original page mentioned you could do that, but didn't say why you'd want to. Now I know why :-). nmcli con modify br0 bridge.stp no Holy chow! This seems to work, no more delay. I should try this at work :-). Now I need a bridge for "bifrost" with no damn slave nmcli con add ifname bifrost type bridge con-name bifrost nmcli con modify bifrost bridge.stp no nmcli con modify bifrost ipv4.method manual nmcli con modify bifrost ipv4.address 192.168.2.99/24 nmcli con modify bifrost ipv4.gateway 192.168.2.1 nm-connection-editor shows me this definition now (though it sure as hell didn't let me define it via the gui). Looks like it works. I got the firewall cranked back up now that bifrost exists and I can start firewall and midgard and the network functions in midgard as expected. Perhaps I finally have everything working with NetworkManager. Ah-HA! I perhaps need this: nmcli con modify bifrost ipv4.never-default true In fedora 33 upgrade I didn't get my.lan search: Try editing /etc/NetworkManager/NetworkManager.conf and putting dns=none after the [main] section entry. Then create a real resolv.conf file: nameserver 127.0.0.1 search my.lan New thing since f36, need to install NetworkManager-initscripts-ifcfg-rh.x86_64 otherwise it won't read the ifcfg scripts. /fedora37/etc/sysconfig/network-scripts/readme-ifcfg-rh.txt has more info. I should try migrating to keyfiles as I get f37 installed. -- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
