how will it be done if my internal network a /24 (being natted too) needs to reach to a outside destination with regular port 22 but traffic coming back from outside to my internal network (the natted address) which now will communicate to one of internal host but on port 5530 for example. All internal hosts have the same public. the only difference is each internal host has different port number?
how will that work? will it be the same scenario like the nat you mention here? just instead of dynamic its static?
nat (inside,outside) source dynamic host_10.10.10.49 host_220.127.116.11 destination static any any service TCP_SMTP_Destination TCP_SMTP_Destination
