testing, so far no go…
I do not have a howto but recalling that once I took a peek at it some video on YT turned up. If I am not mistaken it requires firewall settings.
I was not able to make it work on Layer2 - bridge. I made it work on L3 with NAT, i.e. the same as the default settings LAN > WAN I did CorpLAN > CorpWAN, where in CorpLAN I have eth2 = LAN4 and in CorpWAN thereis radio0.network1 Corp WIFI Client with respective firewall settings [Masquerading and forwarding]
