When an ethernet connection is active, the wifi connection stops working

With Ethernet+WiFi (wlp1s0 addresses in use for proxy):
```
curl -x socks5://127.0.0.1:1080 http://api.ipify.org
(hangs)
```

With WiFi only (wlp1s0 addresses in use for proxy):
```
curl -x socks5://127.0.0.1:1080 http://api.ipify.org
85.XX.XX.XX
```

With Ethernet+Wifi (eno1 addresses in use for proxy):
```
curl -x socks5://127.0.0.1:1080 http://api.ipify.org
84.XXX.XXX.XXX
```

Using socks4 with any configuration results in `curl: (97) Recv failure: Connection reset by peer`.
Running on Arch Linux, have ethernet and wifi. Is this a kernel limitation or something wrong with rust's networking/this program?
