Conclusion
Unsuccessful; a <span>bond</span> can be created, but after binding the <span>zerotier</span> interface, the original interface cannot connect properly to the <span>zerotier</span> network.
Requirements and Objectives
Using <span>iperf</span> for testing with Nanning Mobile, the <span>ipv6</span> can fully utilize the upload bandwidth, while the direct connection to the <span>zerotier</span> network only achieves a bandwidth of <span>10Mbps</span>, likely due to the operator’s <span>QoS</span> restrictions. I want to try using multiple <span>zerotier</span> tunnels to see if it helps.
Process
- 1. Install
<span>luci-proto-bonding</span>; this package will also install other dependencies. - 2. In the device menu of the interface page,
<span>add device configuration</span>, select device type as<span>MAC VLAN</span>, base device as<span>bond</span>, and mode as<span>VEPA (Virtual Ethernet Port Aggregator)</span>, with a device name of your choice. - 3. Then add an interface, name it as you wish, and select the protocol as
<span>Link Aggregation (Channel Bonding)</span>. - 4. Fill in the
<span>ipv4 address</span>with any<span>ip</span>from the interfaces to be aggregated, set the mask according to the actual situation, and in<span>Advanced</span>, check the<span>slave interfaces</span>that need to be aggregated with the<span>zerotier</span>interfaces. - 5. In the firewall’s
<span>nat rules</span>, add a new configuration, select the newly created<span>bond</span>interface for outbound, leave the source address unselected, fill in the target address with the<span>zerotier</span>subnet, select<span>SNAT</span>for the operation, and choose the<span>ip</span>of the newly created<span>bond</span>interface for address rewriting.
Verification
- 1. Check the routing with
<span>ip route</span>; there should be a target route, indicating no issues. Since the router has multiple exits, manual configuration of<span>nat</span>is required, as mentioned in the previous section’s<span>Step 5</span>, because<span>openwrt</span>will only automatically configure<span>nat</span>for the default<span>wan</span>. - 2. Check the aggregation with
<span>cat /proc/net/bonding/bond-bond</span>;<span>bond-bond</span>is the actual interface name, and it should be enabled without issues. - 3. Try to
<span>ping</span>the target address; it was unsuccessful. - 4. Check the network interfaces with
<span>ip addr</span>; the<span>zerotier</span>interface has no<span>ip</span>, indicating that the<span>zerotier</span>interface did not start successfully. - 5. Since I need to use the network, I don’t want to continue for now, so I will revert!
