[OpenSIPS-Users] static nat and 1 to 1 nat

[Alex G]

I'm curious...

Do static or 1 to 1 natted locations produce a null resort  in the received
column of the location table?

Some natted locations show received as the outside ip and contact with the
inside ip which is usually an internal ip behind a firewall.

Some others show null as the received and a the contact has a public address
followed by a port. These devices are obviously natted because I see many of
the same ip with different ports.

Is the difference b/w these 2 types a static nat port or is it something
else?

Thanks!
