Re: [Openvpn-users] Access from Client on a high latency link very slow
I'm in New Zealand and indeed can confirm VPN (basically any kind) works just fine over high-latency links. The only real issue is *packet loss*. If you are on a raw Internet link with (say) 1% packet loss, and mostly do non-stateful stuff like web surfing, then your Internet experience is "pleasant". However, if you run a VPN (any kind) over that 1% packet loss link, it "feels like" 10% packet loss within the VPN - and at that point from an end-user perspective is effectively *broken*. People complain, cat and dogs live together in harmony, world ending catastrophe. Packet loss is the enemy of VPNs - not distance On Tue, Aug 16, 2016 at 12:33 AM, Eduardo Wirth wrote: > Hello > I live and work in Uruguay. > 300ms RTT Europe is expected as a normal delay. > South America Europe traffic is normally done by Miami > I agree with comments from Selva I have worked with satellite > connections (more than 1000ms) ... always it depends on the type of data > you want to transmit and its features (interactive or not) > But correctmente 300ms can work in most scenarios. > > Eduardo > > Dante F.

[Openvpn-users] [Q] may VPN and LAN coexist in the same /24 net?
greetings, please advise may /24 network be devided in half, so the first /25 to be used for VPN pool and the second /25 to be used for LAN? final aim is to advertise whole /24 net via OSPF to the uplink VPN servers VPN /25 <--- +--> uplink VPN srvA clients \| VPN srv1 <--- OSPF +--> uplink VPN srvB /| LAN /25 <--- +--> uplink VPN srvN -- Zeus V.

Re: [Openvpn-users] Access from Client on a high latency link very slow
Hello I live and work in Uruguay. 300ms RTT Europe is expected as a normal delay. South America Europe traffic is normally done by Miami I agree with comments from Selva I have worked with satellite connections (more than 1000ms) ... always it depends on the type of data you want to transmit and its features (interactive or not) But correctmente 300ms can work in most scenarios.
