I’ve seen that GXP 1625 firmware version 126.96.36.199 adds more options to OpenVPN Settings (appreciate it), but I can’t still configure tls-auth (recommended option for hardening OpenVPN).
I have tried to use the " Additional Options" field to add tls-auth support and the ta.key certificate without success. The value I have tried to set to P8460 variable is:
remote-cert-tls+server;<tls-auth>;-----BEGIN+OpenVPN+Static+key+V1-----;<My super secret 2048 bit OpenVPN static key goes here>;-----END+OpenVPN+Static+key+V1-----;</tls-auth>
I can’t send this additional configuration because max allowed length on this variable (P8460) is 512 characters, when a 2048 bit key is already 512 characters long (enable tls and you have run out of space).
Is there any possibility of increasing this max allowed length to P8460 variable or to add tls-auth support as OpenVPN recommends?
Thank you in advance.
