PfSense virtualized drops connection
First of all sorry for my bad english, I hope can explain my problem clearly.
I am having trouble with a PfSense (2.3.2-RELEASE) installed on VMware ESXi 6.0 with basic configurations NAT (default configuration), DHCP server, DNS resolver. There are about 20 devices (computer and smartphones) that access to the Internet by pfSense. I am using Intel 82571EB GibEthernet NIC, dual port.
Initially everything worked fine however when there is many user/sessions connected, the Pfsense drops connections about 1 to 3 minutes and then, without making any changes, the pfSense restore its correct operation.
- I have connected the LAN network directly to the ISP´s modem with same numbers of users/devices and everything going fine.
- I have replaced the pfSense with other appliance firewall with same numbers of users/devices and everything going fine.
- When pfSense is being used i am running a ping command to a site (for instance www.google.com) from my pc connected to LAN face of pfSense, and there are lost packets at moment that the problem happens however at the same time i am running other ping command to the modem IP, there is no drops packets. Could i discard a problem of NIC or VMWARE ESXi server with this behavior? Could it be a NAT problem?
- Anyway I have changed NAT/FIREWALL options from Advanced options but the problem remains.
Do you have any ideas that may be happening?
Thank you in advance.
What's in the logs at the timestamp the errors are happening?
I have looked on status/system log/gateway and there are messages like these:
Feb 9 13:24:48 dpinger WANGW 192.168.9.254: sendto error: 64
The 192.168.9.254 is the ISP's modem address.
On the other hand, this logs are real-time? the last message has date Feb 9 13:24:48, however, if this error message is related with my trouble, should there be messages from today's date? the pfSense firewall is currently operating and failing at every moment.
For the rest, I have not found anything relevant in other logs options.
