Three providers sharing a single public IP address.
Three providers sharing a single public IP address.
You have three ISPs in Brazil—VIVO, TIM, and NET—and you want to manage them together. You need a single public IP for all connections, support multiple ISPs on one device, and ensure continuity if the main link fails. A possible solution involves a DDNS service or a proxy that can switch IPs automatically while maintaining the same public address for all workstations.
Not possible. You do not control your public IP and there is literally no way of doing this.
The only solution I understand is keeping a steady VPN link, either with your router or a server, and sending all traffic through it. The VPN should automatically reconnect when the ISP goes down, so external apps only see your public IP after being connected. If you really need extra bandwidth from other ISPs, you’ll likely have to pay for a service or do significant custom adjustments. Both sides must constantly check all three connection options and switch traffic between them.
Hey everyone. I’m thinking about these options: 1) Linking all three ISPs via a TP-Link RT480T+, a Router X, or even a Mikrotik RB750GR3. 2) Setting up a VPN (like ExpressVPN) to route all my internet through it, possibly using OpenVPN or L2TP/IPSec. I want to know if this works and how it would affect performance. Thanks a lot!
You might notice a brief pause of about one minute as the router detects the loss of connection and attempts to reestablish it.
