Modifying static routes

Hi,

I've just bought myself a cheap android phone (running version 7) to have a play with.. (I've always had iPhones).

I'm curious to know, is it possible to modify the static route table on an android device? I've manged to SSH in, and look at the existing table. I've got the phone connected to a server via OpenVPN, and I'm interested to see if its possible to have a tethered device access the remote network.
