I need to find a way to have the RUTX11 keep Mobile data disconnected (so no data is used) until the ASUS router starts sending data to it. The ASUS must control the failover (using its Dual WAN function) since my Internet service is 2GB download and I dont want to have the RUTX11 as a bottleneck between the cable modem and the ASUS (which has 2.5gb ports)
I disable all the services I could find (update checking, NTP, etc) and its still using a lot of data very few seconds, I think they might be keep alive packets (not sure). But it adds up to 1 to 2 mb a day, and I dont want to pay for ‘not needed data’.
Diagram of situation attached… any help is HIGHLY appreciated.
For this, disabling the mob1s1a1 or mob2s1a1 (depending on which SIM slot you’re using as the primary one) would be the solution, this should stop using any data.
This part will most likely require a custom script to be written; our device will have to read some signals (or, as you mention, incoming traffic) from the end-device to re-enable the mobile interface again.
Regarding this part - if you have failover set up on our device (RUTX11), then by default, the router actively tests connectivity with Ping or Wget to determine availability, which generates data usage you’ve mentioned, if not, that’ll most likely be the mob1s1a1 interface being enabled and occassionally sending the keep-alives / updating information with the provider.
I’d need a bit more clarification regarding your failover case. You say that you want the ASUS to control the failover, so would I be correct if I said that the ASUS sources internet from both the RUTX11 and the modem seen in the topology, and basically switches between them? Regarding that part, we have no expertise with the ASUS modem, so it’ll be hard to give you a good answer.
