Topic: port 25 opened

The content of this topic has been archived on 25 Feb 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hi,

I did a port scanning on my Asus WL-500gP and found that port 25 has been opened. However checking with "netstat -an" I did not find any processes listening to port 25. Below the output of netstat. But telnet to 192.168.1.1 (router's IP) on port 25 there is a response. Has someone encountered a similar problem? Thanks for help in advance.

Kind regards,
Tinho

If you try to reinstall the firmware it's the same?
