I need to revive a thread from December 2020.
I have a /29 network of public IPs for this site.
In the WUI I can only add alias IPs, no netmask for them.
The alias IPs are then configured with a netmask of /24.
Today this fell on my feet, because it breaks routing to neighbouring networks, which are beyond my /29, but within the /24 netmask.
Yes, I can ssh into IPFire and correct this manually, e. g.
ip addr del dev red0 <ip>/24
ip addr add dev red0 <ip>/29
… but I would need to do / script that after every reboot. I would really love to have a reliable and official way for configuring the netmask for my alias IPs. Handlingwise it would be enough, if we could enter the alias IPs as “<IP>/<netmask>” and both - the IP and the netmask - would be visible in the WUI.
Good advice anybody? Or is this homework for the dev team?
I still love IPFire
All the best
