Hello all, I have been having problem with traffic to port 153 keeping the PPP0 link up. I am using iptables to try and filter out (DROP0)this traffic in the INPUT, FORWARD and OUTPUT chains, but can't get it to work. The following is an example from tcpdump
18:47:03.187369 194.165.171.142.4461 > 194.165.172.99.135: S [tcp sum ok]1903694970:1903694970(0) win 8760 <mss 1460,nop,nop,sackOK> (DF) (ttl 121, id 49385, len 48) I also have the following iptables -A INPUT -m state --state ESTABLISHED -j ACCEPT I am thinking that the port 135 traffic that is getting pass the firewall is part of an established connection If this is correct, what might running that requires responses to port 135? Any ideas? Regards Gerard Hooton Department of Microelectronic Engineering U.C.C. Butler Building, Enterprise Centre, North Mall, Cork.
