Hi there,

Im using ngx R61 a single gateway and this is a new setup.
I have installed the rule as below :

src=10.0.0.1 , dst=171.10.1.1 svc=http/https  allow

when i install the rule above the source can't communicate with
destination and i see drops stating the rule is dropped because the
TCP packet out of state. First packet isnt SYN tcp_flags:SYN-ACK.
so what i did was , i disabled the "Drop TCP out of packet" from
Stateful inspection and installed the rule again.
This time i didn't get the above error, instead the traffic is being
dropped by cleanup rule :

Next I did a returning rule as below :

src=171.10.1.1 , dst=10.0.0.1 svc=any allow

now once i installed this, the communication works.

Has anyone experienced this before ? I know this sounds silly but its
happening right now infront of me.. Unless I have missed something.

Please help as Im running out of time.

regards
Fico.
