One way traffic on the client, yet server sends data bask
-
Hello everyone !
I'm faced with a kind-of weird issue where I only have sent packets on my phase2 on the machine that is "client" side.
let me explain my setup :
2 pfsenses, to each one of them its LAN :
192.168.1.0 and 192.168.4.0 both /24 … .4 is on site 1 and .1 on site 2...The 192.168.1.0 side do not have a static IP, and both are behind NAT's...
My Phase1 goes well, but my phase2 only allows for outbout packets on my client, this side doesn't receive anything as show here :
My firewall is fully open, on both side… and I don't know what is happening...
Is that symptom related to anything else than firewall? -
i frequently face this same identical issue, bytes one direction, but zero bytes opposite direction. its reversed on the opposite pfsense. this happens on a pfsense has has 26 or so IPSec tunnels, and just 1 tunnel will do this, the other 19 are functioning normally.
sometimes it self recovers, sometimes this will go on for hours (effectively killing the tunnel and traffic from clients) until i massage it back online.
i have not been able to figure out the root cause.
