Replied In PacketTunnelProvider NEDNSSettings not working on BigSur

Thanks Matt for your reply. This is ruoghly how we are storing DNS settings: tun_dns_config = [[NEDNSSettings alloc]initWithServers:dns_servers]; tun_dns_config.matchDomains = match_domains; tun_dns_config.searchDomains = search_domains; Where dns_servers, match_domains and search_domains are NSString NSArrays. Things are working fine on Catalina (except for Safari browser), On BigSur DNS doesnt seem to work at all. Thanks.

Replied In PacketTunnelProvider Systemextesion : OSSystemExtensionErrorDomain error 8

Is Notarization a mandatory requirement for system extensions to run? Looks like this is the issue. System extension ran successfully after notarization.
