Subject: Iptables problem help required !!!!
To: netfilter at lists.netfilter.org
I am using Red Hat Enterprise Linux AS release 4 (Nahant Update 3) with
Kernel 2.6.9-34.ELsmp #1
I am using Iptables for firewall .
But without firewall I m able to nslookup my own DNS server but whenever I
enabled firewall I am not able to nslookup to my own system.
And log files shows the following entry .
RULE 0 -- ACCEPT IN=lo OUT= MAC=00:00:00:00:00:00:00:00:00:00:00:00:08:00
SRC=127.0.0.1 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=15607 DF
PROTO=TCP SPT=46994 DPT=25 WINDOW=32767 RES=0x00 SYN URGP=0
Jan 22 15:52:01 trench1ams crond(pam_unix): session closed for user
EVEN This rule 0 is also accept rule for SSH not for deny...
I have added rule to accept my own system traffic ...to allow any service
but still tje proble, is same ....
root at trench1 ~]# nslookup trench1
*** Can't find trench1ams: No answer
Please advice me how can I overcome with this problem .......
