Thanks for your quick reply! Renaming of interfaces is no problem, I 
already wrote a plugin
for OpenConnect as client. Did a small rc script since OpenConnect 
itself doesn't deliver ones
but it runs as service and there I rename it:
https://github.com/opnsense/plugins/blob/master/security/openconnect/src/etc/rc.d/opnsense-openconnect#L51-L54

Really appreciate your help! :)
