If a router runs multiple PPP tunnel clients and servers, can their roles be mixed?

• A. Yes, any number any combination
• B. No, roles must be uniform
• C. Only if the router is in bridge mode
• D. Only with separate routing tables

Answer: (A)

Tunnels operate independently, so a MikroTik router can be a PPP client for some tunnels and a PPP server for others at the same time. Because each PPP connection is its own session, the device can initiate outbound connections to some peers while simultaneously accepting inbound connections from others. This means you can mix client and server roles in any combination and in any quantity. Just keep in mind you’ll need appropriate credentials, correct IP addressing for each tunnel, and proper routing and firewall rules so traffic flows where intended. No special mode or separate routing table is required to mix these roles.
