Pepwave MAX with Synology RT2600ac router tips

I did more testing and also saw some old threads.

My issue was how to connect to my Pepwave’s GUI once it had been configured for IP Passthrough. The different ways that worked for me are as follows:

  1. Use my iPhone to connect to the Pepwave’s WiFi. Configure my iPhone to use a static IP address (e.g. 192.168.50.9). Then, access the Pepwave’s GUI using http://192.168.50.1.

  2. Use the gateway that the Pepwave got using its cellular connection (see Web Admin Access with IP Passthrough Active). The challenge with this approach is that you have to get to the Pepwave’s GUI in order to determine what the gateway is, which brings us back to approach #1 above). Another approach: your router (which the BR1 is connected to) may also indicate what this gateway is. For the Synology RT2600ac, go to Network Center->Internet->Secondary Interface (LAN 1)->Connection type. Change Auto to Manual (at least in my case, I normally use Auto), but do NOT click on Apply. Changing Connection Type to Manual will result in the GUI showing the IP address, Subnet mask, and Gateway that it is getting from the BR1. Then, once you know the Gateway, change Connection Type back to Auto. Use the Gateway address in a web browser to access the Pepwave GUI.

  3. Define a route in your router to send traffic with destination 192.168.50.1 to the interface that the BR1 is connected to. For my Synology, I went to Network Center->Internet->Policy Route. Then add an entry with:

Source IP: I use 192.168.1.0/24
Destination IP: 192.168.50.1/24
Interface: LAN 1 (where the BR1 is connected to)

Now, I can just go to http://192.168.50.1 and not have to try to figure out what my cellular modem’s gateway is. I can use any device on my LAN, including the Peplink app on my iOS devices.

Next, onto my 2nd issue (can’t access Internet from iPhone when it connects to Pepwave via Pepwave’s WiFi). I shouldn’t normally have a need to access the Internet this way, but thought it might be useful for debugging, specifically for running Speed Test on my iPhone while it is using my Pepwave.
