Regex : Everything but not [string] - php

Question

I work under symfony, and I would like to configure my pattern in security so that it applies to everything but a certain path. (/Home)
I made that but it doesn't work and I don't know Regex :
pattern: ^/(?!/accueil).*$
There I am obliged to put all my links, which gives:
pattern: ^/(admin|profile|package|securiteInformatique|logout)
So it would be easier to put "all escept" /accueil
My security.yml:
# app/config/security.yml
security:
encoders:
FOS\UserBundle\Model\UserInterface: bcrypt
role_hierarchy:
ROLE_ADMIN: ROLE_USER
ROLE_SUPER_ADMIN: ROLE_ADMIN
providers:
app:
id: bes_auth.user_provider
firewalls:
dev:
pattern: ^/(_(profiler|wdt)|css|images|js)/
security: false
# anonymous: true
# public:
# pattern: ^accueil
# security: false
# anonymous: true
main:
logout_on_user_change: true
# pattern: ^/(admin|profile|packages|securiteInformatique|logout)
#pattern: ^/(?!accueil)
form_login:
check_path: fos_user_security_login_check
login_path: /login_check
guard:
authenticators:
- app.security.login_form_authenticator
- bes_auth.authenticator
entry_point: Site\PagesBundle\Security\LoginFormAuthenticator
logout:
path: deconnexion #nom de la route de déconnexion
target: /
success_handler: bes_auth.authenticator
anonymous: true
access_control:
- { path: ^/admin, role: ROLE_SUPER_ADMIN }
- { path: ^/accueil, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/, role: ROLE_USER }

You should remove the public firewall altogether, remove pattern from your main firewall, and use access_control to handle the permissions.
The following configuration is read by Symfony from the top down, applying the first rule it finds. So any URL beginning with /accueil will be checked against by your main firewall, but will allow the public to view without logging in (because you have anonymous: true). Every other URL (that doesn't begin with /accueil) will require the ROLE_USER role, therefore will force authentication.
access_control:
- { path: ^/admin, role: ROLE_SUPER_ADMIN }
- { path: ^/accueil, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/, role: ROLE_USER }
