Ssh broken pipes in public subnet



  • Hello everyone,

    We have an issue with ssh from our internal LANs to any of our public subnets given by our ISPs. We get broken pipes after a few seconds of log in. Here is our current Pfsense structure: PFsense 2.0.1-RELEASE i386

    WAN1            WAN2
                                                         \           /
                                      Public[WAN1]– PFsense --Public[WAN2]
                                                          /          
                                                     LAN1          LAN2

    Failover is configured. We have servers with IPs on our LAN and our Public. I configured basic manual outbound NAT rules. Each WAN and it's respective Public interface are bridged on pfsense. Everything works normally, Public IPs are accessible externally with no issues, ssh between both LANS have no issues. SSH from any of our LANs to the Public interface is encountered with a broken pipe.

    I've tried basic firewall rules to solve the ssh problem but have had no luck. I don't know what could possibly be causing this problem, especially since absolutely everything else with the configuration works.
