Hello

firehol/iptables blocks frequent traffic from our Google IMAP Server and one update server with port 443.

e.g.:
firehol: IN-internet:IN=eth0 OUT= MAC=00:21:5e:69:e6:3d:xx:xx:xx:xx:xx:xx:xx:xx SRC=64.233.xxx.xxx DST=10.xx.xx.xx LEN=40 TOS=0x00 PREC=0x00 TTL=48 ID=63784 PROTO=TCP SPT=993 DPT=58917 WINDOW=0 RES=0x00 RST URGP=0 

snipped from my firehol.conf:
interface eth1 internet
	...
        server imaps accept
        client imaps accept
        client https accept
	...

The opened ports for the https connection are in status (CLOSE_WAIT).

Why is my traffic blocked?

Thanks,
Daniel
