follows are FORWARD chain. I think I DROP nothing except in the list.
I HAVE modified the policy of FORWARD chain to ACCEPT. that's why i'm
puzzled.
Chain FORWARD (policy ACCEPT)
target prot opt source destination
DROP all -- 0.0.0.0/0 0.0.0.0/0 ipp2p
v0.8.0_rc3 --ipp2p
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state
RELATED,ESTABLISHED
ACCEPT tcp -- 192.168.20.90 192.168.8.66 tcp dpts:137:445
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:445
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:137:139
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:5554
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:1433:1444
DROP all -- 0.0.0.0/0 202.101.43.60
DROP all -- 0.0.0.0/0 202.101.43.67
DROP all -- 0.0.0.0/0 202.101.43.57
And there is another Interest thing (I'm pained with the "interesting thing")
where I use 'sbin/iptables -t nat -A PREROUTING -d Inet2 -p tcp
--dport 8087 -j DNAT --to 192.168.16.100:8087' rule, I can access
http://Inet2:8087 in the LAN, but I can't access http://Inet2:8087
through Internet(I have a machine direct access to internet)
when turn to use 'sbin/iptables -t nat -A PREROUTING -d Inet2 -p tcp
--dport 80 -j DNAT --to 192.168.16.100:8087' then I can access
http://Inet2:80 in the LAN, and both can access http://Inet2:80 in
Internet... that's the thing i had meet
