Hello,
Just a follow up on this issue. My problem is almost similar to this, however the problem only arises at a certain time of the day. At the beginning of the day let say at around 9AM everything is normal. I can see all the clients that are connected, and I can ssh, ping vnc, etc. to all of them. I checked the pfsense, router/firewall, and all clients connections has a state status of "ESTABLISHED:ESTABLISHED". However mostly at night, sometimes around at around midnight, or even at around 10 PM, even if the clients are still connected, I can not ping, ssh, vnc, etc. When I checked the pfsense firewall, the state is either "ESTABLISHED:ESTABLISHED" or "TIME_WAIT:TIME_WAIT", and even when the state becomes ""ESTABLISHED:ESTABLISHED", still I can not ping, ssh, vnc, etc. I restarted the pfsense, the nrserver, and still nothing happens. I leave the issue till the next morning, restarted my computer that I use to connect to the nrserver and voila everything is working perfectly. This happens everyday of the week, that the problem arises at night.
Also when this problem is ongoing, even logging in to the server using the Conguration Explorer, I can not login even if the client I am using is in the same local network.
FYI, two clients that I am using are connected on the same local network as the nrserver. NRserver is on Centos7, dual core 2x cpu xeon processors and connected to a fiber 150/150 internet connection.
Any suggestions on what to do next?
This morning at 8:25 Oct. 23, 2017, I have 4 linux clients, out of the 4 linux clients only 1 I can ping, ssh even though all of the 4 are connected to the nrserver. I checked each one of them and all of them have the virtual ip addresses, nrtap, supplied by the nrserver. However all of the windows clients have no issues at all. I restarted the nrserver, the linux clients, and still the same issue.
Anyone can help on this issues. Thank you.
I made an observation and I think this is what is happening during the night but I am not sure if this is the reason. At night I have 20 additional windows clients that logs in with the neorouter, as soon as the 20 windows logs in, that would result to a total of 27 windows clients, and 6 linux clients, I can't vnc, ssh, ping, anymore with any of the clients. Some of the linux clients suddenly goes offline. However even though all the windows clients are online but I can not vcn, ping to any of the clients anymore.
Anyone following this tread who can give me a hand on how to troubleshoot and find what is causing the problem? Thank you in advance.
