VPN configuration option 'fragment' - ddyx - 10-27-2015 01:03 AM


The server which I'm trying to connect to with any of my Yealink phones requires the 'fragment' and 'mssfix' options, but it seems that the OpenVPN build that comes with the phones' firmware is compiled without 'fragment' support.

Oct 26 00:00:09 openvpn[602]: Options error: Unrecognized option or missing parameter(s) in /config/openvpn/vpn.cnf:9: fragment (2.2.1)

Extract of the config file:
fragment 1400

By the way, OpenVPN 2.2.1 does support this option, so, is there a reason for having it disabled?

Best regards.

I will check with our R&D whether the fragment parameter is supported.
May I know the phone model and firmware you use?

Of course. I'll be using the following models (not sure if all them support VPN):

- CP860
- t20p
- t21p
- t23p
- t29g
- t41p
- t42g
- t46g
- t48g
- w52p

(and t19p which I know already that doesn't have VPN support)

Best regards.
