Re: VPN issues
This is what support sent me. Sent it to my IT to see if Cisco Any connect supports this. My IT is not willing to enable IPv6 due to extra maintaince and security patching. No T-Mobile for me. There are no known issues with VPNs and how they interact with the T-Mobile network to provide internet service. There may be an underlying factor (that can only be addressed by the owner of that VPN client) where there is a need to have ipv4 and ipv6 double stacked into the setup configuration to avoid any service issues. Please have the customer reach out to their VPN client support to check if this is indeed the configuration being used and to also further troubleshoot the VPN issue.Failed outbound VPN connection is caused by a known carrier grade NAT issue relating to T-Mobile's implementation a fully IPv6 network and the implementation of 464XLAT, NAT64, and DNS64 for accessing IPv4 resources. The customer's VPN or VPN server they are connecting to is not properly configured to work with an IPv6 network. This is a third party issue that T-Mobile cannot help with.Thanks for being best part of T-MobileBest Regards!5Visto2likes0Comentarios
