Hi.

I've been using openfortigui for some time now, but after updating my Arch box, all connection attempts fail with: Peer refused to agree to his IP address.

Before update:

Hi,

very likely it's related to the ppp upgrade to the version 2.5.0. You can check this issue on openfortivpn: adrienverge/openfortivpn#1076 on which openfortigui is built on.

Hi, yes, it's because of that option. It would be great if we can configure this in OpenFortiGUI

Just got same problem today.. New openfortivpn have cmd line param for it "--pppd-accept-remote"

Would be nice to add this option to "pppd" section too

  --pppd-accept-remote          Invoke pppd with option 'ipcp-accept-remote'.                                It might help avoid errors with PPP 2.5.0.
