The source ports range from TCP/10000-10040 and the destination server listens on TCP/12000. I need to NAT these hosts to a single IP address as well. Can I use a Dynamic policy NAT Rule for each port to retain the source port during NAT(PAT)? This is on an PIX/ASA.</P> Mon, 11 Mar 2019 14:36:39 GMT https://community.cisco.com/t5/network-security/nat-issue/m-p/1192972#M877709 rsullivan1 2019-03-11T14:36:39Z Re: NAT issue https://community.cisco.com/t5/network-security/nat-issue/m-p/1192973#M877710 <HTML><HEAD></HEAD><BODY><P>Will Policy NAT retain the original source port?</P></BODY></HTML> Wed, 14 Jan 2009 13:14:08 GMT https://community.cisco.com/t5/network-security/nat-issue/m-p/1192973#M877710 rsullivan1 2009-01-14T13:14:08Z Re: NAT issue https://community.cisco.com/t5/network-security/nat-issue/m-p/1192974#M877711 <HTML><HEAD></HEAD><BODY><P>Hi Robert,</P><P> i think yes its all depend on how you define it.</P><P></P><P>HTH</P><P>DAK</P></BODY></HTML> Wed, 14 Jan 2009 14:33:19 GMT https://community.cisco.com/t5/network-security/nat-issue/m-p/1192974#M877711 Davy Ad 2009-01-14T14:33:19Z Re: NAT issue https://community.cisco.com/t5/network-security/nat-issue/m-p/1192975#M877712 <HTML><HEAD></HEAD><BODY><P>If I define a DynNAT Policy for each source port starting with 10000 will it then use port 10000 when it NATs? This is my best thought process as the clients are DHCP hosts and it would difficult to manage them with static IPs and Static NAT entries. </P></BODY></HTML> Wed, 14 Jan 2009 15:41:03 GMT https://community.cisco.com/t5/network-security/nat-issue/m-p/1192975#M877712 rsullivan1 2009-01-14T15:41:03Z
