I cannot access my job's VPN from home
I am currently working from home. I use a company provided laptop with an always on VPN client to access my job's servers. No problem with spectrum cable. I have the brand new grey t-mobile gateway ...
Sorry for the delay. Basically it is an IPv4 vs v6 issue and my IT says they are not going to re-provision the network to work with TMobile's IPv6 network. Here is what Tmob sent me in an email:
"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."
