Question- I have a device that’s essentially a Mediatek chipset running Androld with an LTE modem on it, that speaks RNDIS out the USB port and WiFi and I use that as a USB WWAN device to my AR-750S (as prefer the features and Ethernet ports of my Slate over the WiFi interface the dongle has).

If I were to run the TTL change iptables command listed ("iptables -t mangle -I POSTROUTING -o wwan0 -j TTL --ttl-set 64") on the Slate, do you think it would have any effect (the “MiFi” device is also running NAT)?
