any tcp connection not able to survive
I really need your help. Earlier I had
My issue is about any TCP connection from an internal machine connecting to
an outside machine. I am ssh'ing from 172.16.0.9(internal machine) to
192.168.1.105(external machine) without any issues.
Once I remove the lan cable on the master firewall external interface, my
existing ssh connection is dropped. However, pfctl -s state still shows the
self tcp 192.168.1.105:22 <- 172.16.0.9:2291 ESTABLISHED:ESTABLISHED
self tcp 172.16.0.9:2291 -> 192.168.1.100:64001 -> 192.168.1.105:22
These lines can be seen from both firewalls and they're identical.
my latest pf.conf are @
and i have removed tons of lines but still these config didn't help.
I also tried telnet and it had the same behavior.
However, if the lan cable from master external interface is not connected
and I setup a new ssh connection from same machines, and I put back the
cable to master external interface, ssh is still running fine and ifconfig
in master shows that it's the master in CARP interface again.
tcp connection from External->Internal works GREAT though, tcp sessions not
So can anyone please help me what my issue is?
