Setting up a WI-FI router as an access point with a 3G modem for anonymous surfing the net?

Question

network hardware

Friends, welcome.
Switching to the Tails system, I ran into the problem of accessing the Internet via a USB modem. Tried many models and operators. The result is constant crashes or even failures when connecting and forming "bulbous" networks. I came to the decision to use a router that will distribute the Internet from a 3G modem. But the question arose about the anonymity of using such a configuration.
The bundle is as follows:
- a working 3G modem with the left SIM card without blocking access to Tor (inserted into the router)
- WI-FI router Zyxel Keenetic 4G I
plan to create a network to access the Internet from Tails (all outgoing connections via Tor).
What are the key points to look at when setting up a router for maximum anonymity? Will the VPN->Tor chain work if I "plug" the VPN settings into the router?

Answer 1

1. Refuse Wi-Fi (and any radio modules).
2. Disable Tor-relay.
3. (and as Artem said ) do not allow "leakage" of requests for the "pipe" with any connections / disconnections of any interfaces.

Answer 2

WiFi and anonymity are orthogonal things. Simka can be at least left, at least right, at least middle - it gives exactly the same data about its location (well, traffic, of course, is taken into account).
And here, you understand what's the matter - you can hang up at least twenty VPN->Tor cascades - you can't change the fact that the most vulnerable link in this entire system is a person ...
