The email doesn't work when I do this. Here are the rules as of now. /sbin/iptables -A INPUT -p tcp --syn -s 10.2.2.120/32 --destination-port 22 -j ACCEPT /sbin/iptables -A INPUT -p tcp --syn -s 10.2.2.120/32 --destination-port 1241 -j ACCEPT /sbin/iptables -A INPUT -p tcp --syn -s 10.2.2.6/32 --destination-port 25 -j ACCEPT /sbin/iptables -A INPUT -p tcp --syn -j DROP Mark -----Original Message----- From: aljuhani [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 08, 2003 2:56 PM To: [EMAIL PROTECTED] Subject: Re: Sendmail problem Ok then add this RULE to the top before the DROP rule and restart your firewall. /sbin/iptables -A INPUT -p tcp --syn -s 10.2.2.120/32 --destination-port 25 -j ACCEPT [EMAIL PROTECTED] ----- Original Message ----- From: "Drozd, Mark" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 08, 2003 21:43 Subject: RE: Sendmail problem > These are the only rules as this is a client workstation. > > Mark > > > -----Original Message----- > From: aljuhani [mailto:[EMAIL PROTECTED] > Sent: Tuesday, July 08, 2003 2:38 PM > To: [EMAIL PROTECTED] > Subject: Re: Sendmail problem > > > > Found the problem. > > > > IPTABLES was set for the following; > > /sbin/iptables -A INPUT -p tcp --syn -s 10.2.2.120/32 > > --destination-port > 22 > > -j ACCEPT > > /sbin/iptables -A INPUT -p tcp --syn -s 10.2.2.120/32 > > --destination-port 1241 -j ACCEPT /sbin/iptables -A INPUT -p tcp > > --syn -j DROP > > > > Once I flushed IPTABLES it works fine.
