Configure sstp-client to connect to office with EAP

Hi all,

I am trying to connect to a windows vpn server hosted by my company using sstp-client. In short, i am trying to do exactly what is happening in this post (for basically the identical reasons). However, i am not having much success

i have the sstp-client package installed and when i run:
sstpc --cert-warn --user vpnusername --password vpnpassword server:port
I get:
/dev/pts/1: Error loading shared library /usr/lib/pppd/2.4.9/sstp-pppd-plugin.so: no such file or directory
/dev/pts/1: Couldnt load plug sstp-pppd-plugin.so
Which i resolved by ln -s the correct library to the correct directory (is this the right thing to do?)

However, after that, i get the:
**Error: Connection was aborted, Reason was not known, (-1)
and cant seem to move from it.

Ive had an openwrt router for a while, but this is the first time ive tried something like this and am a bit over my head - any advice is greatly appreciated. Ive been reading a number of posts on configuring this from the command line, but i might have missed a few steps

Cheers

Tried luci-proto?
