Re: [Openvpn-users] Windows XP firewall blocking OpenVPN?

[Kenneth K. <ken...@gm...>]

Hi Ralf, and the list

I'm seeing the same behaviour between a linux client (2.0.6) and linux
server (2.0.2) where the timeour is consistently 4 minutes. We're
tearing our hair out here and I was hopinh that you might have
discovered the reason for this behaviour.

Best,
