I tried to set the OpenVPN server on RT-AC86U (382.1_2) with custom configuration but this field is limited to 170 characters. Is it possible to make it wider? Thanks.
Not possible. Broadcom limits those variables to 255 chars, and I have to encode it in base64 to retain formatting, hence cutting it down to 170 chars.
This is a stupid HND platform limitation from Broadcom.
