As i am totally new to openwrt, I struggled to set it up the way i wanted it, all the guides i found seemed to be either obsolete, too technical or just didnt cover what i needed, so I thought I would make one.
This is how to connect an openwrt router to an existing network via a wireless bridge, and create a 2nd network on a seperate subnet for the purpose of connecting to the vpn via both wifi & lan connections.
I made a pdf, it can be downloaded from my google drive here:
or from mega here:
I put this together from memory, an hour or so after i managed to accomplish it.
Hopefully someone will find this useful, i hope i did not forget anything.
