Hi all,

Has anybody seen a tool for converting Junos firewall rules into Cisco
ACL's?
I know Juniper have one to go the other way.

I have several hundred to do, and manually will be a pain and liable to
error.

Junos rules look like :-

filter test-out {

        term permit_tcp_established {
            from {
                tcp-established;
            }
            then accept;
        }
        term permit_database_access {
            from {
                source-address {
                    xxx.xxx.xxx.xxx/32;
                    yyy.yyy.yyy.yyy/29;

                }
                destination-port 5432;
            }
            then accept;

         term default_reject {
            then {
                log;
                syslog;
                reject;
            }
        }
    }
