Starlink and Peplink Balance

I have recently joined Starlink’s beta program. They don’t disclose any of their networking details. They allow you to hook into their wifi router with a network out, but I found it was both unstable and had poor performance.

I have managed to connect the Starlink dish to one of my WAN ports in DHCP/NAT mode, with an automatic DNS. I have a second provider with the same settings.

It works great, however in order to use the management app, I believe need to be able to pass through to WAN1 to allow a LAN client to manage the dish. I have tried just about all of the Peplink balance settings to do so, an outbound policy to all WANs, adding as an additional IP and pushing all traffic to that IP as a NAT rule, adding a firewall rule, and an management admin. I was trying to get this IP setup to pass through to the WAN1 gateway, but didn’t manage to get that working either.

I cannot ping the address, except when the dish initially boots up, they must hide it from ping.

Any suggestions?


Possible the Starlink device is preventing any client not in its subnet from connecting to its admin interface? Kinda what Peplink lets you configuré as well. Nice feature. :stuck_out_tongue_winking_eye:

Can you connect directly to its subnet and see if you can ping and connect via their mobile app?

When using the starlink router it builds a network and I believe has an admin passed through to the dish as

Any idea how to get the peplink to pass through any IP calls for an address not pingable?

Just create an outbound policy rule: Source=Any > Destination=IP Address > Algorithm=Enforced > WAN (Starlink)

That doesn’t seem to have gotten it…

Not saying this is it, but generally that would not be a properly defined /24 destination “IP NETWORK”. Make it

Or within the drop down for destination be sure to choose “IP ADDRESS” with the single IP.

What IP address scheme does the Starlink WAN provide?

Maybe try adding a Static Route for to the gateway IP of the Starlink interface. According to 8.1.1 release notes you may need to be running 8.1.1 for those to work in drop-in mode. Maybe that doesnt apply to this scenario

When the Starlink dish / modem boots up it comes up as as the gateway, it then renegotiates to with as the default gateway. The IP address and gateway changes address with each reboot.

Subnet mask is
When I put the static route in I get an error that the gateway is not on the local network.

I am running the WAN in DHCP/NAT mode not drop in.

If I put firewall logging on to the address I see a pass entry in the log from a source on the lan (cell phone with the app running) to the destination. I just don’t know if it’s hitting the WAN.

As soon as I can order a starlink dish I will test this out.

In the meantime, run a PCAP from the support.cgi page.

We need to see if the packets are leaving the router via the WAN link or not coming back.
and we need to see what MAC addresses they are tagged with.

The starlink forums imply that you should add a route to netmask on your WAN interface (or add the entire This causes the router to broadcast an ARP request for and then communicate directly to that MAC address. Peplink does not allow static routes on the WAN interfaces of Balance devices.

The Outbound Policy produces a similar but subtly different result. The packet will go out the WAN, but it will be tagged with the MAC address of the default router. If the hardware of the OOB interface only responds to its own MAC, then it will not pick up that packet.

Do you have a spare WAN port? (USB dongle?)… You can put in a switch between starlink and the Balance and then also connect to a second always on WAN port configured for and use that for OOB communication.

I installed a B20X yesterday with a DSL bridged modem. To attempt to manage the modem ( I set an Outbound Policy Enforced out the WAN interface. The packets leave the correct interface, but as expected they are tagged with the MAC address of the default router, and the DSL modem’s management interface does not pick them up.

Depending on your network a traceroute may show that an ICMP is returned from the next hop router.

You can also check with the CLI interface. Ping from the WAN interface:

support ping wan 1 (replace 1 with the number of the wan interface)


support arp

If does not show up in the arp table, then there are no way to reach the device without a static route or other solution.

FusionHub allows WAN static routes.

When I had this same configuration, I had to use the second USB/WAN interface to manage the DSL modem, but with this new installation I don’t have a spare WAN Ethernet.

I tried a number of workarounds and was able to connect via an Access LAN, but this bridges the secure and insecure domains, and required adding a static route on the modem (which would not be available on starlink)

I think if we don’t have a good static route solution by the time starlink expands south, I will just use an old juniper SRX to bridge the Starlink WAN and securely connect a mangement VLAN to That will probably also give me IPv6 access to test as well since peplink doesn’t support v6 in any reasonable way (passthrough on wired wan #1 is not support)

for what its worth, I too am running a B20x and was able to set a WAN policy to forward requests to my cable modem @ and i am able to access my cable modem.

Yes, and If you test with the CLI ping test you will get an answer back, probably with a MAC entry as well.

We can call this In Band traffic. the cable modem reads the bridged stream and intercepts any destinations. The zyxel DSL modem and it seems the starlink modems don’t behave the same way and are Out of Band traffic, and want the packets sent to the MAC address of their management module.

This is very interesting, thanks for sharing Paul!

I did take the diagnostics. I cannot ping it losses all packets. does not show up in the arp interface. Did you want me to transfer you the diagnostic files?

No, that just re-enforces what I see with the DSL modem… That Starlink has the same behavior.

Ask peplink to support static routes on the WAN interface, there are about to be a lot of Starlink Customers, viewing the diagnostics via a phone is a core activity and they may want to support them directly.

For now, you will either have to allocate an additional WAN interface (If you have one free) or use an old router to handle the OOB traffic. To use a second router set its WAN to /24 Assign the LAN to /24. On the peplink set an Access VLAN 101 to have an IP address of and then add a static route for via Connect the 2 WAN ports and Starlink to a Switch, and connect the second router’s LAN port to the Access Vlan 101 port.

I have an ethernet USB converter and GigE switch ready for when I can order Starlink.


I give that a big thumbs up - peplink needs to do whatever is needed to fully support starlink on the WAN. I will likely put in several hundred myself. We sell phone service and cellular backup Internet to pizza restaurants, but they need decent WAN.
I have a waiting list of over a hundred locations waiting until they have some kind of high speed Internet to sign up with us.


Here is what I wound up doing. I put an unmanaged switch hub in between the dish and the peplink, then put the original starlink router off of the hub; after adding a Poe box. I have to connect to the starlink WiFi network to use the app. It did a firmware update as soon as I hooked it up, not sure if both the dish and then router or just the router. The starlink router is forced to be at and doesn’t let you into any settings. I tried to hook a peplink ap300m up instead but all lights flash on it, I suspect a hardware error.

The starlink router no longer wrecks havoc with the rest of my network like it was doing when plugged directly off the starlink router network output port, even though I had noting on the 192.168.1 network.

I would only watch that the system is ok with having two router IP’s on the same dish. Both the peplink and starlink routers now have DHCP addresses. There is nothing illegal about this from a network point of view, but traditionally cable and DSL providers limit the DHCP clients on the remote side. Starlink may not be regulating this now, but they may in the future.

Thanks Paul, the starlink app shows “connected devices”. Any device that connects to the Starlink router shows up in the list, plus the Peplink shows up as "one device with the WAN mac address showing up. This leads me to believe it’s acceptable behavior (for now).
