I am now using port forwarding. The outgoing traffic for mail is being stamped with my Pix address instead of the mail address. Some of the mail is being rejected becasue the pix outside address has no rDNS. Is there a way to make the out going mail use the mail server external address instead if the PIX external address.</P><P></P><P>static (inside,outside) tcp x.x.x.10 www x.x.x.37 www netmask 255.255.255.255</P><P>static (inside,outside) tcp x.x.x.10 https x.x.x.37 https netmask 255.255.255.255</P><P>static (inside,outside) tcp x.x.x.10 pop3 x.x.x.37 pop3 netmask 255.255.255.255</P><P>static (inside,outside) tcp x.x.x.10 smtp x.x.x.43 smtp netmask 255.255.255.255</P><P></P><P></P><P></P> Mon, 11 Mar 2019 11:02:56 GMT https://community.cisco.com/t5/network-security/pix-nat-and-port-forwarding/m-p/746431#M970546 tlienskt 2019-03-11T11:02:56Z Re: PIX NAT and port forwarding https://community.cisco.com/t5/network-security/pix-nat-and-port-forwarding/m-p/746432#M970547 <HTML><HEAD></HEAD><BODY><P>Use this command and this should resolve your issue:</P><P></P><P>nat (inside) 10 x.x.x.43</P><P></P><P>global (outside) 10 x.x.x.10</P><P></P></BODY></HTML> Mon, 27 Aug 2007 19:19:22 GMT https://community.cisco.com/t5/network-security/pix-nat-and-port-forwarding/m-p/746432#M970547 hsajwan 2007-08-27T19:19:22Z
