        after I disable the gateway monitoring, what would be the best way to determine if i have a problem at all?

          you could run a batch file on one of your clients and let it run for a while.

          something like this:

          
@echo off

:START

ping -n 4 4.2.2.2 >nul

if %errorlevel% == 1 (
  echo Internet offline >> C:\Internet.txt
  Time /t >> C:\Internet.txt
)

Timeout /t 30
@set errorlevel = 0

GOTO START

            awesome thanks Heper.. at least that gives me a start..  I was starting to think it might be an Intel network card that I have, probably isn't..

              hey guys, stopping apinger seems to have helped with the errors and internet dropping, thanks for that.

              I am now having problems with very high pings and slow internet.  sometimes the ping to 8.8.8.8 is 20ms, sometimes it is 800ms.  whenever I ping AirVPN, it is a 2-400ms.    I have been using DNS from UNblock, where is the setting to get the DNS from my ISP automatically?  i couldn't find them under WAN settings.

              Any other hints to figure out what is going on with ping swings and generally high pings?  I cannot even use VPN it is so slow now, never had a problem before.

                Is DNS Forwarder or DNS Resolver enabled (which one)?

                DNS Forwarder uses the DNS Servers specified in the System: General Setup.
                DNS Resolver uses the DNS root servers.

                Client DNS server assignment can be overridden in Services: DHCP server.

                  i have DNS forwarder enabled and just LAN and Localhost selected as this is how my VPN is supposed to be setup when i get it working.

                  I plugged my cable modem directly into my laptop and everything is fast.  I then rebooted and connected PFsense again and it seems better.  I think i am starting to get how DNS is assigned, thanks NOYB.  Does DNS determine my Pings?

                  I can switch between my ISP dns and Unblock's dns and they both seem fairly fast pinging most websites.  When i ping some of the AIRVPN servers though, I am still getting the high hundreds though, not sure what that is about.  If I can't get good pings to them, i won't be able to get the VPN up and working.

                  Any way to figure out where it is going off the rail?

                  I was able to go to pingtest.net and get an A grade on my connection.  The only problem now i guess are the very high pings to the servers at AirVPN.

                    DNS should have nothing to do with ping times (assuming name resolves to same IP address).  Once name is resolved to an IP address DNS is out of the picture.

                    To see where the slowness may be try a trace route (tracert on a Windows client).

                      does this mean anything?  the request timed out on step 2.  it seemed fast until step 7.

                        No the hop #2 time out is not significant.  Just means that router does not respond to pings.
                        Don't see any of the 400 to 800 ms pings you mentioned in the opening post.

                        That doesn't look too bad really.  Here's what it looks like from here for comparison.

                          Oh and by the way that hop #2 is probably the default gateway.  So no wonder apinger was having trouble.

                          So it was probably detecting and marking the WAN interface as down.  That's probably why the VPN was going down.

                            hate to sound like any more of a dumbass but is there a way to fix that?

                            i did another clean install and now am only using WAN and LAN.  I also tried plugging my WAN into the other Intel NIC which gets me a different IP address from my ISP to just test, didn't seem to make a difference.

                              Configure apinger to monitor the next available hop.  Or leave apinger disabled.

                                thanks NOYB, i configured it to the 2nd hop and am not getting any errors, thanks for the tip.  If it gives me any problems, i will disable it but i kind of like having it on. Going to try to setup OpenVPN client tomorrow to see how it works.  Have a good night.

                                  got the VPN up and working, seems to be better.  Having a few VPN errors though.  Not sure if it is totally taking the tunnel down or just reporting.  Going to google this a little.

                                    hey guys, VPN is up and down like crazy..  here are the logs..  frustrating..  the rest of the network stuff seems good now, this seems like it is the only outstanding problem. Switching next weekend from 30mb cable to 100mb ADSL, can't wait.  any ideas?

                                      Try disabling gateway monitoring for both VPN and WAN in System>routing. Openvpn by itself is capable of detecting and reconnecting if the vpn connection is broken.

                                          It happens at 09:14:49, 09:33:35, 10:31:05. Check other logs like gateway, openvpn etc to see what's happening at these times…or probably before these times.
                                          It could easily be that you haven't added custom options from airvpn config into the ovpn client setting's advanced box, like i think once I added mssfix from the vpn's config files, and BAM it was stable.

                                            This is what is in my advance box, I'm pretty sure you are right though, it is probably something in here:

                                            remote-cert-tls server;comp-lzo no;verb 4;explicit-exit-notify 5;key-direction 1;auth SHA1;keysize 256;key-method 2;tls-cipher TLS-DHE-RSA-WITH-AES-256-CBC-SHA;

                                            I just updated to 60 internet today, clearing all my logs and see what I get, pretty sure it will be the exact same.  Nice though, going through the tunnel I get 60, outside the tunnel 70.
