Hi,
not sure if this is the right place for documentation errata.
I was reading and testing the Documentation Example at https://docs.opnsense.org/manual/how-tos/sslvpn_instance_s2s.html (https://docs.opnsense.org/manual/how-tos/sslvpn_instance_s2s.html) and found a possible error here:
https://docs.opnsense.org/manual/how-tos/sslvpn_instance_s2s.html#trust
The Client Certificate must not set to be for server use, this will definitely not work:
QuoteSet Type to Server
Hope that helps,
j.
