Why does SSH write to the router's IP log?

Question

SSH

Ubuntu 12.04
OpenSSH_6.6.1p1 Ubuntu-2ubuntu2, OpenSSL 1.0.1f 6 Jan 2014
When connecting via SSH, it logs the router IP currently issued (dynamic IP), the domain is attached to the machine via afraid.org, and I connect through it. Even if you enter the IP that is received at a given time in Putty, the picture does not change.
What could be the problem? I experimented with logging levels - it did not help.
Thank you.
UPD: in the webmin logs, the IP of the router also shines, the router: Huawei HG532e.

Answer 1

Thoughtfully read the wiki on the subject of NAT.

Answer 2

and what you wanted that in a broad gull it would be visible ip behind natom? or servos SP which goes through the provider's gateway?
