When I turn off snort the connection flows perfectly. Looking at snorby I see no event of the connection being dropped. I've included the command we are running from a internal server that is behind the snort. I also included the tcpdump from this same server for the connection. wget https://216.52.211.91/label/health.aspx --2014-05-08 20:37:33-- https://216.52.211.91/label/health.aspx Connecting to 216.52.211.91:443... connected. 20:37:33.443962 IP 10.2.2.1.52661 > 216.52.211.91.443: Flags [F.], seq 3298140140, ack 2463587275, win 8208, options [nop,nop,TS val 2824990869 ecr 3731400338], length 0 20:37:33.444478 IP 216.52.211.91.443 > 10.2.2.1.52661: Flags [R.], seq 1, ack 1, win 8208, length 0 20:37:33.989510 IP 10.2.2.1.59800 > 216.52.211.91.443: Flags [S], seq 3306929108, win 65535, options [mss 1460,nop,wscale 3,sackOK,TS val 2824990923 ecr 0], length 0 20:37:34.071548 IP 216.52.211.91.443 > 10.2.2.1.59800: Flags [S.], seq 361712399, ack 3306929109, win 4140, options [mss 1380,nop,wscale 3,nop,nop,TS val 3731482846 ecr 2824990923,sackOK,eol], length 0 20:37:34.071610 IP 10.2.2.1.59800 > 216.52.211.91.443: Flags [.], ack 1, win 8208, options [nop,nop,TS val 2824990932 ecr 3731482846], length 0 20:37:34.071750 IP 10.2.2.1.59800 > 216.52.211.91.443: Flags [P.], ack 1, win 8208, options [nop,nop,TS val 2824990932 ecr 3731482846], length 139 20:37:34.154367 IP 216.52.211.91.443 > 10.2.2.1.59800: Flags [.], ack 140, win 517, options [nop,nop,TS val 3731482928 ecr 2824990932], length 1368 20:37:34.154462 IP 216.52.211.91.443 > 10.2.2.1.59800: Flags [.], ack 140, win 517, options [nop,nop,TS val 3731482928 ecr 2824990932], length 1368 20:37:34.154490 IP 10.2.2.1.59800 > 216.52.211.91.443: Flags [.], ack 2737, win 7877, options [nop,nop,TS val 2824990940 ecr 3731482928], length 0 20:37:44.153373 IP 216.52.211.91.443 > 10.2.2.1.59800: Flags [R.], seq 4233:4288, ack 140, win 534, length 55 any help or suggestions would be great, I would like to disable the rule that is blocking this connection but like I said I cannot see which rule blocked it.
