OK. Three things here (possibly) if I am reading your quesiton correctly. First you need a NAT rule to do the translation inbound (if you are natting). Second, and acl that defines the access. Third, assign that acl to an interface.
Ip nat inside source static udp ex.te.rn.ip 123 in.te.rn.ip 123 ext Then in an acl you'd define the access to that translation Access-list 101 permit udp host re.mo.te.ip host ex.te.rn.ip eq 123 THEN On the outside interface... (maybe ser0/0 ?) Ip access-group 101 in More questions?
