I just bought MikroTik Chateau 5G. Internet provider is Tmobile through a SIM card inserted into the router. No other device is used. Internet works just fine, but I cannot configure VPN to get it to work. I updated to the newest software version - 7.12.1. The router uses default private ip which is 192.168.88.1 and the vpn 192.168.89.1. I have VPN Access enabled in the quick setup and from what I see vpn server setups automatically with all required ports enabled to allow l2tp/ike connection (udp, 500, 1701, 4500). In IP>Firewall>Nat there is configured chain srcnat action=masqueradeI. cannot connect to the VPN no matter which protocol I use LT2P or IKEv2. When I try to connect using VPN address as it is shown in the quick setup and I get an error that says that the server L2TP does not response. I saw somewhere in the Cloud tab a messenge "Router is behind a NAT. Remote connection might not work." and I guess that might be the case. I've got a public IP but it is different from VPN server adress seen in mikrotik web panel. Tried to connect through macos, windows and ios - same problem. Can someone try to help me solve this?
