Hallo, I've FreeBSD acting as router in small home internet use ipfilter/ipnat, I've question:
- How long ipnat keeping state valid rule on table, for example: The rule has been expire on X second with sending RST TCP flag or rule already finish with sending FIN TCP flag after Y second etc (On default mode ipnat). I try to find on source code about this but never find it. Because for two week my friend (Work in ISP) have problem, every 4 minutes until 15 second internet link has been disconnecting, so we try to capture packet via bridging ethernet and finally we know the problem is shortly timeout on his NAT box for handshake connection. Thanks you. -- budsz
