Pfsense blocking traffic between two machines
-
I have setup two Netgate XG-7100 machines, with IPSEC site to site VPNs. Traffic is traversing the VPN correctly for all the computers except two machines. Initially, the two computer were able to transfer SMB data back and forth through the VPN. After transferring a large amount of data between the two computers, the Netgate XG-7100 devices start blocking the communications between the two computers.
Any help is greatly appreciated..

Do you have an IDS/IPS like Snort or Suricata listening? It may have blocked the host for flooding or some other rationale.

No, I have not implemented any IDS/IPS systems at this time.

Anything in the firewall log regarding those two clients? If it's working once, it should continue to work.
