With v5.10.3 (#494) the previous default behaviour of binding to 0.0.0.0 for the symfony server was removed. In v5.10.4 (#525) the old behaviour got supported again with the command line flags allow-all-ip or listen-ip.

As those feature changes are kind of breaking changes in certain project situations, I would suggest to support the above flags also in the .symfony.local.yaml to minimize the impact of the change to just adapting the general symfony config file of the project.

I am not sure, if that just means changing local/project/config.go line 38 to

ListenIp      string `yaml:"listen_ip"`

As there is is no AllowAllIp config option, maybe that is also not necessary for the yaml file (I could set the listen_ip to 0.0.0.0 or maybe set it to empty string, if I want that behaviour).
